Nitrile gloves are manufactured from a rubber known as acrylonitrile-howeveradiene rubber and are free from latex proteins. These gloves specifically suit those individuals who’re latex-sensitive. Gloves made from nitrile are available in numerous thicknesses and types resembling ambidextrous examination type and in hand particular kinds, reminiscent of lined and unlined. Nitrile rubber can be known as Buna-N, Perbunan, or NBR. It is a artificial rubber copolymer of acrylonitrile (ACN) and howeveradiene. Nitrile butadiene rubber (NBR) is a household of unsaturated copolymers of two-propenenitrile and various howeveradiene monomers (1, 2-butadiene and 1, three-butadiene). The physical and chemical properties vary depending on the polymer’s composition and the polymer shows excellent resistance to grease, fuel, and different chemicals. This makes NBR a useful material for manufacturing disposable lab, cleaning, and examination gloves. A latest improvised form of (NBR) is the Automobileboxylated Nitrile Howeveradiene Rubber (XNBR). In this polymer, there are additional carboxyl teams 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-automobileboxylated Nitrile rubber.
Specific Advantage: These gloves are thrice more puncture-resistant than natural rubber gloves. Therefore, these nitrile gloves additionally supply protection from most solvents and oils, and finest suited for protection from abrasion, minimize and punctures. It’s imperative to note in this context that needlestick and sharps accidents are the commonest 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’ material which technically signifies that the material just isn’t topic to shedding and is exceptionally low in residual chemicals. These gloves may be readily sterilized by irradiation without any reduction in physical characteristics and thus, these gloves are quickly taking on as the fabric of alternative in Cleanrooms like research labs.
Accelerator Free Gloves
Accelerators are chemical substances utilized in nitrile gloves manufacture to ensure a speedy vulcanisation of the film and are liable for most of the positive traits of the glove together with its energy, elasticity and barrier performance. These accelerators have been off late linked to Type IV, delayed hypersensitivity response leading to allergic contact dermatitis. Most of these accelerator chemical compounds fall in three fundamental groups of chemical compounds, namely, thiurams, thiazoles and dithiocaramates. Low Accelerator Gloves or Accelerator Free Gloves are recent improvements within the industry. Low Accelerator Gloves are manufactured under optimized circumstances that make the most of exceptionally low ranges of accelerator and are available in the market. A technology that utilizes a pre-treatment of the dip mix eliminating the requirement of an accelerator is within the development stage towards production of accelerator free gloves.
Biodegradable Disposable Glove
Regular nitrile gloves should not prone to enough microbial activity to begin breaking down the polymer’s molecular structure and hence the process of degradation and reclamation of the used gloves depends upon light, heat, mechanical stress and moisture. Biodegradable Disposable Nitrile Glove is a current significant major 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 independent licensed laboratories utilizing 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 fabric in the glove excrete enzymes that depolymerize the nitrile. This results in a final product composed of biogases and inert humus.
