Nitrile gloves are manufactured from a rubber known as acrylonitrile-butadiene rubber and are free from latex proteins. These gloves specifically suit those people who are latex-sensitive. Gloves made from nitrile are available in several thicknesses and types akin to ambidextrous examination type and in hand specific types, resembling lined and unlined. Nitrile rubber can also be known as Buna-N, Perbunan, or NBR. It’s a artificial rubber copolymer of acrylonitrile (ACN) and butadiene. Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and varied howeveradiene monomers (1, 2-butadiene and 1, three-howeveradiene). The physical and chemical properties range relying on the polymer’s composition and the polymer shows excellent resistance to grease, fuel, and other chemicals. This makes NBR a useful material for manufacturing disposable lab, cleaning, and examination gloves. A recent improvised form of (NBR) is the Carboxylated Nitrile Butadiene Rubber (XNBR). In this polymer, there are additional carboxyl groups R-COO- on the double bond of the butadiene half besides the sulfur bridges that make ionic cross links with zinc Zn++ to give improved physical properties as compared to a non-carboxylated Nitrile rubber.
Particular Advantage: These gloves are 3 times more puncture-resistant than natural rubber gloves. Hence, these nitrile gloves also offer protection from most solvents and oils, and finest suited for protection from abrasion, cut and punctures. It is crucial to note in this context that needlestick and sharps accidents are the most typical methodology of transmitting blood-borne pathogens like Hepatitis B Virus, Hepatitis C Virus and HIV between patients and the health care professionals.
Innovations
Cleanroom Gloves
Nitrile is a ‘clean’ materials which technically indicates that the fabric is just not subject to shedding and is exceptionally low in residual chemicals. These gloves could also be readily sterilized by irradiation without any reduction in physical traits and thus, these gloves are quickly taking over as the material of choice in Cleanrooms like research labs.
Accelerator Free Gloves
Accelerators are chemical compounds utilized in nitrile gloves manufacture to ensure a speedy vulcanisation of the film and are liable for many of the positive characteristics of the glove including its power, elasticity and barrier performance. These accelerators have been off late linked to Type IV, delayed hypersensitivity reaction leading to allergic contact dermatitis. Most of those accelerator chemicals fall in three basic teams of chemical substances, namely, thiurams, thiazoles and dithiocaramates. Low Accelerator Gloves or Accelerator Free Gloves are recent improvements in the industry. Low Accelerator Gloves are manufactured under optimized situations that make the most of exceptionally low levels of accelerator and are available in the market. A technology that makes use of a pre-remedy of the dip combine eliminating the requirement of an accelerator is within the development stage towards production of accelerator free gloves.
Biodegradable Disposable Glove
Common nitrile gloves should not prone to adequate microbial activity to begin breaking down the polymer’s molecular construction and therefore the process of degradation and reclamation of the used gloves relies on light, heat, mechanical stress and moisture. Biodegradable Disposable Nitrile Glove is a recent significant main breakthrough. These gloves manufactured with a new eco friendly technology has been shown to accelerate the biodegradation of nitrile in biologically active landfills and anaerobic digesters as validated by impartial licensed laboratories using internationally recognized test methods. Biodegradable Disposable Nitrile Glove is composed of natural materials designed to make the glove attractive to microbial activity. These microorganisms on consuming the material in the glove excrete enzymes that depolymerize the nitrile. This leads to a final product composed of biogases and inert humus.
