Areas of application of nitrile gloves: What are nitrile gloves suitable for??


Because of their numerous advantages, nitrile gloves are very popular in many areas of application.

 

Nitrile gloves in medicine

On the one hand, nitrile gloves are very popular in medicine because they form a good barrier between the hand and potentially harmful microorganisms. Nitrile gloves thus offer a good oneProtection against bacteria and viruses as well as before direct contact with excrement and body fluids.
For this reason, nitrile gloves are worn in hospitals as well as by doctors in private practice and in ambulances.
If you are looking for nitrile gloves for medical use, you must always make sure that the gloves are certified according to the European Standard 455 (EN 455). This standard decides whether a disposable glove is approved for use in the medical field or not.

Nitrile gloves in the care of the elderly and the sick

Nitrile gloves are also popular in outpatient and inpatient care. Here, too, they protect against direct contact with body fluids, bacteria and viruses.

Since medical interventions are often necessary in nursing (e.g. change of bandages or infusions), we recommend that you also choose disposable gloves for this that European standard 455 fulfill.

For non-medical work (e.g. washing patients), disposable gloves that are not certified according to European Standard 455 may also be sufficient.

 

Blue nitrile gloves in the food industry

Even when handling food professionally, disposable gloves must be worn around onethe highest possible hygiene standard to enable. Since nitrile gloves are avery good resistance to oils and fatshave, they are preferred in the food industry.
Compared:In contrast, both latex and vinyl gloves are not suitable for contact with fatty foods.
Because if vinyl gloves come into contact with fats, chemical substances (so-called plasticizers) can be released from the glove and migrate to the food. In order to protect the consumer from the consumption of these potentially harmful plasticizers, vinyl gloves must not be used when handling fatty foods.

Likewise can Loosen latex proteins from latex glovesif this with fatty foods come into contact. If the latex proteins pass onto the food and are then consumed by a latex allergy sufferer, this can lead to allergic reaction to lead.

 

In the food industry are mainlyblue nitrile gloves very popular. Because if a glove tears or is lost, a blue nitrile glove or a blue glove can be tornfound again much easier than a different colored glove. Because there are no naturally blue foods. Blue is therefore the most noticeable and the easiest to filter out.
When choosing your nitrile gloves for the grocery store, make sure they have aFood safety declaration to have. You can find out whether a nitrile glove is suitable for handling food on the product detail pages.
Disposable gloves are popular not only in the food processing industry, but also in gastronomy. Because disposable gloves symbolize hygiene and cleanliness for the customer.
Since fatty foods are also used in many cases in gastronomy, it is advisable to use nitrile gloves here as well.
So that the disposable gloves can come into contact with the various foods without any problems, care should also be taken in gastronomy to use the glovesFood safety declarationbe able to show.

Disposable chemical gloves for laboratories

Nitrile gloves are also preferred in laboratories. Because nitrile gloves offer significantly better chemical resistance than latex and vinyl gloves.
When looking for disposable chemical gloves, make sure that the gloves have the Comply with European Standard 374. Because in the course of this standard it is checked to what extent a disposable glove protects against chemicals.

Nitrile - chemical resistant gloves for cleaning work

When handling cleaning agents, it is also important that hands are well protected. Becausemany detergents contain chemicals and other substances that can attack the protective layer on the hands. Therefore, make sure that the disposable gloves that you use when handling cleaning agents have agood protection against chemicals Offer.
Here, too, you can refer to the pictogram of theEuropean standard 374 orientate. If the glove box is marked with the pictogram, the glove can basically be used as a disposable chemical glove. The letters under the Erlenmeyer flask show you which test chemicals were used to test the chemical resistance of the glove.

Since there are no specifications for the color of disposable gloves in the cosmetic field, beauticians and tattooists have a free choice.

What is nitrile actually?

 

Nitrile gloves are made fromAcrylonitrile butadiene rubber (nitrile rubber for short). The material is also under the abbreviation“NBR” known, which abbreviates the English name Nitrile Butadiene Rubber.t.
In contrast to latex rubber, nitrile rubber is not a natural substance, but achemical product. Strictly speaking, the material consists of cross-linked polymer molecules made of acrylonitrile and 1,3-butadiene. The nitrile rubber isElastomers, making the material aSubgroup of plastics counts.

Properties of nitrile:

  • very elastic, tear-proof and tensile strength
  • resistant to alcohol
  • resistant to oils and fats (vegetable & animal)
  • resistant to alkalis and diluted acids
  • resistant to water with a maximum temperature of 80CC
  • resistant to aliphatic hydrocarbons (e.g. gasoline, propane, butane)

 

Powdering of nitrile gloves

Nitrile gloves (as well as latex and vinyl gloves) are available both with and without powder coating.
Powdered nitrile gloves have the advantage that they can also be used with damp or even wet handseasier to put on leave as powder-free gloves. At the same time, however, powdered disposable gloves also bring somehealth disadvantages with himself.
When you take off powdered disposable gloves, the powder is swirled into the air. If the powder is now inhaled, theRespiratory tract and mucous membranes irritated become. Coughing fits and redness may occur.
Especially withLatex glovesstops powderinghealth risk Because the latex proteins are bound to the powder in the glove. If a latex allergic person inhales the latex proteins in high concentrations, this can lead to aallergic reaction to anaphylactic shock to lead.
In thefood industryit actually is strictly prohibitedto wear powdered disposable gloves. Because after the powder has been whirled into the air, it will settle again sooner or later. If the powder lands on the food, it becomes contaminated and can be harmful to the health of the consumer.

  • leaves powder residue on clothing

 

 

Polymer coating vs. chlorination

Nitrile gloves are not all nitrile gloves. Because these disposable gloves differ not only in their color and powdering, but can also be differentiated from one another in other properties - depending on which steps a glove went through during the manufacturing process.
The production of disposable gloves can be imagined as follows:
First, hand-molds are made from ceramicspowdered with corn starch (powder). The molds are then dipped into the liquid materials - nitrile, latex or vinyl - and then dried. The cornstarch is used to make the gloveAfter drying it is better to let it detach from the ceramic molds. If a glove is not treated further, this cornstarch will stick to the gloves and it is a powdered disposable glove.
As the powdering of nitrile gloves, howeverswirled in the air and then inhaled, the powder often becomesWashed out of the disposable glove using a mixture of water and dissolved chlorine. In this way, the powder is removed and processed into powder-free disposable gloves.
In addition to this chlorine solution, aPolymer coating used to the glovesskin-friendly andsmoother to be made as powdered disposable gloves.


Depending on the area of application and personal preferences, you can differentiate between the following varieties:

  • chlorinated Disposable gloves
  • double chlorinated Disposable gloves
  • polymer coated Disposable gloves (+ slight chlorination to activate the polymer layer)
  • polymer coated and chlorinated Disposable gloves

 

 

Chlorinated nitrile gloves

In the chlorination process, the disposable gloves are alreadyon the production linewhile they are still attached to the ceramic molds, into aChlorine solution dipped which is the surface of the glovesetches and thereby makes it smooth. Therefore have chlorinated glovesalways a smooth inside. Because when the gloves are removed from the glove mold, the chlorine-treated outside becomes the inside of the glove.

Since the chlorination takes place directly on the production line, this process is also referred to as “Online chlorination” (on line = on the production line).).
Chemical residues that were used in production are largely washed out of the gloves by the chlorination. That way it becomes Minimized allergy risk. In addition, online chlorination Powder residues as well as fluff or the like washed off the gloves. The disposable gloves are thus to a certain extent“cleaner” than powdered gloves that have not been chlorinated.

In addition, the gloves are chlorinatedsofter andsmoother. The surface willsmooth andresidue-freewhich makes the gloveseasier to put on. In addition, the gloves are chlorinatedPH-level neutral and thusmore skin-friendly.

How smooth a glove gets depends on thatChlorine content in the water-chlorine solution.The more chlorine there is in the solution, the smoother the glove will be.
Then the glovewashed out several timesto remove chlorine residues.

Double chlorinated nitrile gloves

In addition to the chlorinated gloves, you can also opt for double chlorination. Theinside is double chlorinated gloveseven smoother, making the gloves accordinglymake it easier to put on. In addition, by a double chlorination, forAdditional chemical residues washed out of the gloves making the disposable gloves stillskin-friendly become.

Basically, the more chlorine is used for chlorination, the smoother the surface will be.

 

Advantages of chlorinated disposable gloves

  • cleaner than powdered gloves
  • smooth inner surface
    → easy to put on
  • chemical residues are washed out
    → minimizes the risk of allergies
  • improved skin tolerance through pH neutrality
  • more resource-saving and environmentally friendly than a polymer coating

 

Polymer-coated nitrile gloves

A polymer coating helps with thatTo minimize the risk of allergies from disposable gloves. It is used in both nitrile and latex gloves.

The polymer coating provides a kind of Barrier between the hand and the glove itself, so that the hand is not in direct contact with the glove for too long.

So that the polymer coating can fulfill its purpose, there is also a light one hereChlorination necessaryto activate the polymer coating. The gloves are first turned into one on the assembly linePolymer coating immersed while they are still adhering to the ceramic hand molds. Then the gloves are removed from the ceramic molds and put in a kind of oversized washing machinewashed out in a light chlorine solution.
Since the chlorination takes place off the production line, this process is also usedOffline chlorination called.

Nitrile gloves with polymer coating AND chlorination

When looking for the perfect nitrile glove, you don't have to choose between the advantages of polymer coating and chlorination.

Because there are also disposable gloves that polymer-coated on the inside and at the same time Chlorinated inside and out are. This way, the glove is beautiful both inside and out smooth. They are therefore suitable, for example, to help patients in Care facilities to wash, as the gloves are comfortable soft on the skin feel. They combine the advantages of polymer coating with those of chlorination.

Advantages of polymer-coated and chlorinated gloves:

  • chemical residues are washed out
    → minimizes the risk of allergies
  • skin-friendly thanks to its pH neutrality
  • smooth surface on the inside
    → are easy to put on
  • smooth surface on the outside
    → also feel nice and soft on the outside

 

Extra strong nitrile gloves for extra safety

In addition to their coating, nitrile gloves also differ in their coatingMaterial thickness. If they are exposed to particular stress, shouldNitrile gloves extra strong be. This can be done, for example, inworkshopsor even with intensive onesCleaning workbe the case. Also, it is recommended that your disposable nitrile gloves be extra strong when you are using themChemicalswork.
