Nitrile gloves are manufactured from a rubber known as acrylonitrile-howeveradiene rubber and are free from latex proteins. These gloves specifically suit those people who are latex-sensitive. Gloves made from nitrile are available in different thicknesses and types similar to ambidextrous examination type and in hand particular types, reminiscent of lined and unlined. Nitrile rubber can 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 two-propenenitrile and various howeveradiene monomers (1, 2-butadiene and 1, 3-howeveradiene). The physical and chemical properties differ depending on the polymer’s composition and the polymer shows wonderful resistance to grease, fuel, and other chemicals. This makes NBR a useful materials for manufacturing disposable lab, cleaning, and examination gloves. A recent improvised type of (NBR) is the Automobileboxylated Nitrile Howeveradiene Rubber (XNBR). In this polymer, there are additional carboxyl groups R-COO- on the double bond of the butadiene part besides the sulfur bridges that make ionic cross links with zinc Zn++ to present improved physical properties as compared to a non-carboxylated Nitrile rubber.
Specific Advantage: These gloves are 3 times more puncture-resistant than natural rubber gloves. Therefore, 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 injuries are the most typical method of transmitting blood-borne pathogens like Hepatitis B Virus, Hepatitis C Virus and HIV between patients and the health care professionals.
Nitrile is a ‘clean’ material which technically indicates that the fabric just isn’t topic to shedding and is exceptionally low in residual chemicals. These gloves could also be readily sterilized by irradiation with none reduction in physical characteristics and thus, these gloves are quickly taking up as the fabric of alternative in Cleanrooms like research labs.
Accelerator Free Gloves
Accelerators are chemicals used in nitrile gloves manufacture to ensure a rapid vulcanisation of the film and are chargeable for most of the positive characteristics of the glove including its strength, elasticity and barrier performance. These accelerators have been off late linked to Type IV, delayed hypersensitivity reaction leading to allergic contact dermatitis. Most of these accelerator chemical substances fall in three primary teams of chemical compounds, namely, thiurams, thiazoles and dithiocaramates. Low Accelerator Gloves or Accelerator Free Gloves are current innovations within the industry. Low Accelerator Gloves are manufactured under optimized conditions that make the most of exceptionally low levels of accelerator and are available in the market. A technology that utilizes a pre-treatment of the dip combine eliminating the requirement of an accelerator is in the development stage towards production of accelerator free gloves.
Biodegradable Disposable Glove
Common nitrile gloves aren’t prone to ample microbial activity to begin breaking down the polymer’s molecular construction and therefore the process of degradation and reclamation of the used gloves depends on light, heat, mechanical stress and moisture. Biodegradable Disposable Nitrile Glove is a current significant major breakthrough. These gloves manufactured with a new eco pleasant technology has been shown to accelerate the biodegradation of nitrile in biologically active landfills and anaerobic digesters as validated by unbiased certified 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 material in the glove excrete enzymes that depolymerize the nitrile. This ends in a remaining product composed of biogases and inert humus.
