Nitrile vs Vinyl Gloves - A Detailed Comparison

0 votes
21 views

What are the differences between nitrile vs vinyl gloves? Which is better for what purposes?

While nitrile gloves are generally more expensive than vinyl gloves, they offer a number of advantages over vinyl. When choosing disposable gloves, the main issue to consider is which ones are appropriate for the task at hand.

The purpose of this guide is not to give you a definitive answer on which type of glove is better. Rather, it will provide information about nitrile and vinyl gloves that allow you to make your own decision based on your needs.

What are Nitrile Gloves?

Nitrile is a synthetic rubber that offers flexibility, long-life durability, and chemical resistance. Nitrile is a synthetic elastomer designed to be moisture resistant. Disposable nitrile gloves are flexible and durable making them ideal for industrial tasks, the food industry, and health care applications. They are also great for most medical environments.

What are Nitrile Gloves Made From?

Nitrile Gloves are made from synthetic rubber called acrylonitrile-butadiene rubber. This material provides users with heightened tactile sensitivity, allowing you to pick up small items such as screws and needles more accurately. They are also more puncture resistant.

The disposable glove materials were first developed to solve the common problems of allergic reactions to natural rubber latex gloves and low protection against solvents. They are the most popular glove materials used in many industries and the ideal alternative to disposable latex gloves.

What are Nitrile Gloves Used For?

Nitrile gloves are used for a variety of industrial, domestic, and healthcare purposes. Nitrile gloves are the popular choice for health care workers, dentistry, beauty shop owners, healthcare providers, laboratory work, food handling, chemical handling, and general industrial tasks.

Nitrile protective gloves can also be found in the automotive industry and janitorial industry. Nitrile was found to be more durable than vinyl when performing gripping tasks with power tools and picking up tools like wrenches and screwdrivers.

 

What are Vinyl Gloves?

Vinyl Gloves are also made of a synthetic polymer but are often less thick and, as a result, less durable. Vinyl is great for non-hazardous situations but does not have the flexibility of nitrile.

What are Vinyl Gloves Made From?

Vinyl gloves are made from a blend of synthetic rubber, plasticizers, and additives called PVC. They were also developed as a great option for those suffering from latex allergies.

What are Vinyl Gloves Used For?

Vinyl gloves are frequently used for food handling, food preparation, low-risk health care applications, light clean-up jobs, and repetitive assembly line or manufacturing tasks. These products are commonly used in non-hazardous situations and low-risk infection environments because of the low level of protection offered. They work great for the food and beverage industry.

 

For decades, latex gloves were the king of the disposable glove industry. These days, though, as latex allergies are increasingly common, latex products have a more niche application. Either way, the material remains well-suited to handling certain jobs--and ill-suited to others.

Not sure whether latex gloves are the right fit? Here’s a look at what latex gloves are used for.

What are Latex Gloves?

You might be surprised to learn that the materials behind Latex Rubber Gloves are naturally occurring. In fact, while dip-molded latex might lead you to believe these are purely synthetic gloves, latex is actually a naturally occurring plant material.

Basically, latex is any polymer in a water-based or viscous form. Natural latex, or natural rubber latex, is derived from the rubber plant Hevea brasiliensis and is a complex emulsion of proteins, sugars, oils, starches, tannins, alkaloids, resins, and gums that coagulate when exposed to the air.

We transition from the rubber plant to commercial latex by taking fresh latex and transforming it through a process of blending, coagulation, and drying.

What are Disposable Latex Gloves Used For?

Latex gloves have long been popular power players among disposable gloves, whether they’re powdered latex gloves or powder-free gloves. These days, workplaces are more conscious of latex allergies.

Even so, latex remains a popular glove material for its comfort, stretchiness, and tactile sensitivity. This makes latex a popular compound among a specific population: the medical industry.

In terms of medical gloves--especially surgical gloves--few materials can match the dexterity and tactile sensitivity of a latex glove. This is incredibly important for work requiring extreme precision, such as surgery. That said, even regular physicians remain frequent users of latex gloves. Even a regular physical exam needs tactile sensitivity, and on that front, latex gloves are hard to beat.

Latex is also quite popular among workers who need frequent glove changes, whether that’s the healthcare industry or elsewhere. In many cases, you would need powdered gloves to provide the same comfort level as latex powder-free gloves.

 

POLYETHYLENE GLOVES are our most economical glove. PE Products are most often used for light duty tasks that require frequent glove changes. This glove has a loose fit design for easy on and off applications, and is especially useful in food service lines, deli counters, and other high volume applications. Our clear PE Gloves are available in high density, low density, cast poly, and a new stretch hybrid version that is also available in blue. All PE gloves sold by The Safety Zone are powder free and non-medical as well. All Poly Gloves are 100% Phthalate Free, 100% Latex Free and 100% Silicone Free.

 

Non Woven Shoe Covers are the newest environmentally friendly material, anti-slip and anti-static, and are loved by customers. The most important feature of disposable shoe covers is that they are easy to use and can be used in a wide range of applications, saving you the trouble of taking off your shoes.

What Is SPC?

Stone plastic composite, solid polymer core, or SPC flooring, is a vinyl flooring material that has a rigid core made from powdered limestone, polyvinyl chloride and stabilizers. Sometimes, you might see it referred to as “stone polymer composite flooring.” It is dense, dimensionally stable, quiet and strong. Pure from Beauflor are great options in this category and both include an attached pad.

SPC and WPC – Key Differences to Know

Similar to dryback luxury vinyl flooring (which is the traditional type of luxury vinyl that requires an adhesive to install), SPC and WPC flooring are comprised of multiple layers of backing that are fused together. However, unlike dryback flooring, both flooring options feature a rigid core and are a harder product all around.

Because SPC’s core layer is comprised of limestone, it has a higher density in comparison to WPC, though is thinner overall. This makes it more durable compared to WPC. Its high density offers better resistance from scratches or dents from heavy items or furniture being placed on top of it and makes it less susceptible to expansion in cases of extreme temperature change.

One important thing to note is that although SPC and WPC are often marketed as being waterproof, they are actually water resistant. Though neither product is entirely waterproof if submerged underwater, topical spills or moisture should not be an issue if properly cleaned in a reasonable amount of time.

Applications

Rigid core products including WPC and SPC were originally created for commercial markets because of their durability. However, homeowners have started using rigid core as well because of its ease of installation, design options and durability. It is important to note that some SPC and WPC products vary from commercial to light commercial use, so it is best to always consult your manufacturer to know which warranty applies.

Another highlight for both SPC and WPC, aside from their easy-to-install click locking system, is that they do not require extensive subfloor prep prior to installation. Though installing over a flat surface is always a good practice to be in, floor imperfections like cracks or divots are more easily hidden with SPC or WPC flooring due to their rigid core composition.

And, when it comes to comfort, WPC is generally more comfortable underfoot and less dense than SPC due to the foaming agent it is typically comprised of. Because of this, WPC is especially well suited for environments where employees or patrons are constantly on their feet.

In addition to offering more cushion when walking, the foaming agent in WPC provides more sound absorption than SPC flooring does, although many manufacturers offer an acoustic backing that can be added to SPC. WPC or SPC with acoustic backing are ideal for settings where noise reduction is key such as classrooms or office spaces.

What's the Difference Between Lvt Vs. Lvp?

LVT (Luxury Vinyl Tile) and LVP (Luxury Vinyl Plank) are two different types of luxury vinyl flooring. LVT is vinyl flooring designed in a tile shape, whereas LVP is vinyl flooring designed in planks to resemble traditional hardwood floor planks.

Here are some more details on these two wonderful luxury vinyl flooring choices…

What's Luxury Vinyl?

Luxury vinyl is a specific type of vinyl flooring. Old-school vinyl flooring used to be offered in sheet form only, and therefore wasn't able to mimic the realistic natural materials that luxury vinyl floors now can. Modern LVT and LVP floors are now offered in countless patterns and colors, and designed so that they appear to look almost exactly like natural materials such as wood, stone, and tile. Some LVT and LVP flooring options are even textured to appear like these materials as well. Many LVT and LVP floors even have seams for grout, and the planks can come in narrow or wide styles, as can the tiles.

Are LVT and LVP floors waterproof?

Yes! Both LVT and LVP floors constructed from layers of plastic, so they're waterproof, making them an ideal flooring choice for any room in your house, especially kitchens, bathrooms, and basements. LVT and LVP floors are designed to withstand moisture, heavy foot traffic, and plenty of scratches and spills.

What's VCT flooring then?

VCT stands for Vinyl Composite or Vinyl Composition Tile flooring. Though VCT floors are also made with some vinyl in them, unlike LVT floors, they contain less plastic and more natural materials such as limestone. Because of this, VCT floors are more porous than LVT floors, and thus they are not as waterproof and require more maintenance.

What about Engineered Vinyl flooring?

Engineered Vinyl flooring, or Engineered Vinyl Plank (EVP), is a subset of LVPs. EVPs are simply even more durable than many LVP options, as they're built with the strongest high-density fiberboard core, and have a rigid stone-based core. EVPs are often considered the luxury vinyl planks on the market that most closely resemble real hardwood floors, but personal preference will often determine this for you!

What Is The Most Durable Garage Floor Covering?

Many chairs for gamers look like they belong on a racetrack. But the flashy aesthetics are secondary. The true value is the ergonomic support these models provide. If you suffer from back pain in a standard office chair, a gaming chair is one of several upgrades can help. Here we compare racing-style gaming chairs vs office chairs. Learn which type is a better fit for your needs.

 

Head-to-head, a gaming chair is more visually striking than a standard office chair. It stands out with a bucket seat, tall backrest, thick padding, and support pillows. Meanwhile, a generic office chair typically comes with a padded fabric seat and mid-back support.

 

Beyond first impressions are important functional differences. A racing-style gaming chair has more adjustable parts than an office chair. Its seat, armrests, support pillows, and backrest can all adjust to meet the needs of the user. In contrast, a regular office chair lacks adjustable parts. As a result, the user needs to adjust to the chair.

 

Over time, working or playing video games in a non-adjustable office chair can cause serious health issues. Common symptoms of inadequate seating include chronic back pain, lethargy, brain fog, and migraines.

 

Today, sedentary lifestyles are endemic. People spend the majority of their days sitting. There are consequences. Health issues like lethargy, obesity, depression, and back pain are now common. Gaming chairs fill a crucial need in this era. Learn about the benefits of using a gaming chair. It’s true! Upgrading from a cheap office chair can help you feel better, sit longer, and be more productive.

 

The bottom line is that human bodies work best when active. Despite that, the typical desk worker spends as much as fifteen hours sitting each day. Compounding that problem is how employees sit while at work.

 

Most offices equip their staff with cheap, traditional office mesh chairs. These come with fixed armrests and a fixed backrest that doesn’t recline. This style of chair forces users into static sitting positions. When the body tires, the user must adapt, instead of the chair.

 

Companies buy standard office chairs for their employees mainly because they are cheap. That is despite many studies over the years pointing out the dangers of fixed sitting habits.

 

In fact, the science is clear. A fixed sitting position limits movement and overworks muscles. Then, the muscles need to work harder holding the trunk, neck, and shoulders up against gravity. That accelerates fatigue, making things worse.

 

As muscles tire, the body will often wilt into a slouch. With chronic poor posture, users suffer a host of health issues. Circulation slows. Misalignments in the spine and knees place unbalanced pressure on the joints. Shoulder and back pain flares up. As head cranes forward, pain radiates up the neck, exploding into migraines.

 

Under these brutal conditions, desk workers become weary, irritable, and demotivated. In fact, several studies show a connection between posture and cognitive performance. Those with good posture habits tend to be more alert and engaged. In contrast, poor posture makes users more prone to anxiety and depression.

 

Ergonomic advantages of a kids gaming chair and adults gaming chair

Standard office chairs force users into static sitting positions. Over full-time sitting hours, that leads to poor posture, joint strain, lethargy, and discomfort. In stark contrast, gaming chairs are “ergonomic”.

 

That means they come with adjustable components that meet modern ergonomic standards. Those emphasize two essential qualities. First, the presence of adjustable parts that support a healthy sitting posture. Second, features that promote movement while sitting.

Peptides vs proteins - what's the difference?

If you’re looking for the difference between peptides and proteins, the short answer is ‘size’.

Both peptides and proteins are made up of strings of the body’s basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins.

But the definition, and the way scientists use each term, is a little loose. As a general rule, a peptide contains two or more amino acids. And just to make it a little more complicated, you will often hear scientists refer to polypeptides – a chain of 10 or more amino acids.

Dr Mark Blaskovich from the Institute for Molecular Bioscience (IMB) at The University of Queensland in Australia says approximately 50-100 amino acids is the cut-off between a peptide and a protein. But most peptides found in the human body are much shorter than that – chains of around 20 amino acids.

There’s also an important variant of peptide called the cyclotide. As with the peptide and the protein, the cyclotide is also comprised of a string of amino acids, but unlike the others, the ends of a cyclotide are joined together to form a circle.

As we’ll discuss below, this structure is important in the manufacture of therapeutic peptide-based drugs.

As for proteins, biochemists generally reserve the term for large peptide molecules, which can either be one long chain of 100 or more amino acids – a ‘complex polypeptide’, if you like – or they can be comprised of several amino acid chains joined together.

Haemoglobin, found in your red blood cells and essential for carrying oxygen, is such a protein. It’s made up of four different amino acid chains – two with 141 amino acids each and two with 146 amino acids each.

Why peptides are the ‘next big thing’ in medical research

Biochemists are excited by the possibilities presented by peptides and proteins as pharmaceuticals because they so often mimic exactly the behaviour of a natural ligand – the substance that interacts with the receptor on an enzyme or cell to cause a biological process.

This gives peptide drugs the potential to be more precisely targeted, with fewer side effects than small-molecule drugs.

Within the body, there are lot of different hormones that react with cells and trigger different biological processes. Often these are peptides, either cyclic versions or straight, linear ones.

And then there’s the matter of how fast that peptide breaks down, which causes some stability issues, but in terms of safety, can be a positive.

“We think peptides are the future of drugs for reasons of being more selective, more potent and potentially safer, because when a peptide eventually breaks down it just breaks down into amino acids, and amino acids are food, basically,” says Professor David Craik, who leads IMB’s Clive and Vera Ramaciotti Facility for Producing Pharmaceuticals in Plants.

There are also manufacturing considerations that make peptides attractive – their length allows them to be chemically synthesised, as opposed to proteins that are generally expressed in yeast or mammalian cells.

So that’s peptides. What are the applications for proteins?

The most promising application of proteins is as antibodies, which are themselves a form of protein.

Particularly in anti-cancer applications, there are a lot of antibodies either in the clinic or under development. Two well-known examples are Herceptin (trastuzumab) for breast cancer, and Humira (adalimumab) for rheumatoid arthritis and other autoimmune diseases.

The advantage of using proteins is the same as for the drug applications of peptides – they mimic something that is natural in the body, or replace something that’s missing or damaged.

In the case of antibodies, protein-based drugs use the same strategy as the body does to target things. That way the drug can provide the specificity required, while also avoiding the off-target effects that a small molecule drug can have, causing bad side effects.

When will we see new peptide-based medications?

Stability can be an issue, as peptides can degrade very quickly, and that means it can be difficult to dose a patient with a peptide.

And according to your body, peptides and proteins are basically just food, which makes administering peptide drugs in an oral form quite difficult, as the body promptly digests them.

“That’s why drug developers often try going from a peptide and mimicking it with a small molecule instead, because the small molecule potentially has better properties for a drug, where the small molecule stay around in the body longer and can be administered orally,” Dr Blaskovich said.

But the challenge is to get the small molecule to mimic the peptide.

“Billions are spent by the pharmaceutical industry trying to do this,” Dr Blaskovich added. “That’s why if you’re able to come up with drugs that are peptides, rather than having to convert them into small non-peptidic molecules, it’s potentially a much faster way to develop a potent, selective, and apt drug.”

The pharmaceutical industry remains sceptical, mainly due to the stability issue, but also the difficulty in getting orally administered peptides to cross the barrier of the gut and be taken up by the bloodstream.

But intravenous and subcutaneous use of peptides as drugs is becoming more common. There are around 60 FDA-approved peptide drugs on the market, with about 140 peptide drugs in clinical trials, and over 500 in pre-clinical (before human testing) development.

There are agricultural applications too

While the stability of peptides is a challenge to be overcome in human use, it’s a double-edged sword, and may be an advantage in some agricultural uses. The speed of degradation of peptides used as insecticides or fungicides means that they are not going to persist in the environment.

So creating greater stability of peptides can work both ways.

If the stability of the peptide can be tailored, then it can be made to last long enough to work on the crop, but then also to degrade.

This means it would not cause the long-term problems of DDT, for example, which can exist for hundreds of years.

Why are experts so excited about peptide drugs?

Cyclotides - the central focus of Craik’s work - have great potential to address the issues of stability of peptide drugs.

As they structurally form a circle, cyclotides do not have the weak point of loose ends that speed up degradation by our digestive enzymes. They are further stabilised by several interlocking cross-links, forming a compact, very stable structure. This helps them reach their target intact, even when taken orally.

Blaskovich’s group is working on two promising peptide-based antibiotics to deal with growing antibiotic resistance.

The first of these is to enhance the glycopeptide (peptides with sugar molecules on them) antibiotic Vancomycin, by trying to make it a super-vancomycin that more selectively targets bacterial cells. This approach starts with vancomycin as the core, with additional groups added on to interact selectively with the bacterial cell instead of a mammalian cell.

The aim is to increase its potency at killing bacteria and reduce the unwanted side effects it has on human cells.

The second research program is developing antibiotics that attack Gram negative bacteria - generally considered the more difficult to fight. These peptides are cyclic lipopeptides (peptides with a fatty acid, or lipid, attached) with eight to 10 amino acids.

You might have already taken a peptide-based drug

One of the best-known peptide-based drugs is exenatide, which is marketed under the name Byetta. It’s used to help control blood sugar levels in type 2 diabetes patients.

It works by increasing the insulin production in response to meals and is a synthetic form of the peptide found in the venom of the Gila monster - a species of venomous lizard native to the US and Mexico.

It’s a linear peptide containing 39 amino acids that was developed some 10 years ago, and is now widely used.

Defining Antiaging Nutraceuticals

The term antiaging can incorporate a broad range of nutraceutical possibilities. For the purpose of this article, let’s define antiaging nutraceuticals as those nutracentical ingredients that help to address health and wellness issues associated with aging. In this context, that would potentially include nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health. Ahead, we touch on a few promising contenders.

The benefits of organic food

How your food is grown or raised can have a major impact on your mental and emotional health as well as the environment. Organic foods often have more beneficial nutrients, such as antioxidants, than their conventionally-grown counterparts and people with allergies to foods, chemicals, or preservatives may find their symptoms lessen or go away when they eat organic fruit and vegetable powder.

Organic produce contains fewer pesticides. Chemicals such as synthetic fungicides, herbicides, and insecticides are widely used in conventional agriculture and residues remain on (and in) the food we eat.

Organic food is often fresher because it doesn’t contain preservatives that make it last longer. Organic produce is sometimes (but not always, so watch where it is from) produced on smaller farms nearer to where it is sold.

Organic farming tends to be better for the environment. Organic farming practices may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. Farming without synthetic pesticides is also better for nearby birds and animals as well as people who live close to farms.

Organically raised animals are NOT given antibiotics, growth hormones, or fed animal byproducts. Feeding livestock animal products increases the risk of mad cow disease (BSE) and the use of antibiotics can create antibiotic-resistant strains of bacteria. Organically-raised animals tend to be given more space to move around and access to the outdoors, which help to keep them healthy.

Organic meat and milk can be richer in certain nutrients. Results of a 2016 European study show that levels of certain nutrients, including omega-3 fatty acids, were up to 50 percent higher in organic meat and milk than in conventionally raised versions.

Organic food is GMO-free. Genetically Modified Organisms (GMOs) or genetically engineered (GE) foods are plants whose DNA has been altered in ways that cannot occur in nature or in traditional crossbreeding, most commonly in order to be resistant to pesticides or produce an insecticide.
