Nitrile butadiene rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. Its products have excellent oil resistance, high wear resistance and good heat resistance. Using high quality nitrile butadiene rubber with other additives, refined processing; No protein, no allergic reaction to human skin, non-toxic, harmless, strong and durable, good adhesion.
NBR is prepared by emulsion polymerization of butadiene (H2C=CH-CH=CH2) and acrylonitrile (H2C=CH-CN). It is mainly produced by low temperature emulsion polymerization and has the properties of two homopolymer. The butadiene component gives the copolymer elasticity and cold resistance. The acrylonitrile component has strong polarity. The -CN base can make the copolymer have good chemical corrosion resistance, especially the oil resistance (refers to the alkane oil). Increasing the content of acrylonitrile in rubber can improve the oil resistance of rubber, but the elasticity and cold resistance will be reduced. Its products have good oil resistance, higher wear resistance and better heat resistance.
Unlike latex gloves, nitrile gloves are insoluble in non-polar solvents and can effectively tolerate non-polar alkanes and cycloalkanes, such as n-pentane, n-hexane, cyclohexane and other reagents, most of which are labeled green. It should be noted that the protection performance of nitrile gloves for aromatic hydrocarbons varies greatly. In benzene, for example, degradation grade P, the overall degradation and penetration grade of the glove is marked red. In toluene, degradation grade F, penetration time 34 minutes, permeability F, marked yellow. In xylene, the degradation grade is G, the penetration time is 96 minutes, the permeability is F, and the label is green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery acid), 30% hydrogen peroxide are all labeled as green, degradation grade E, penetration time >360 minutes. Methanol, ethanol, n-propanol, amyl alcohol, cyclohexanol and other alcohols are also labeled green. Nitrile gloves with poor or no protective performance against dimethylformamide, acetone, butanone, tetrahydrofuran, trichloromethane, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate are labeled red.
Nitrile gloves are a kind of protective gloves commonly used in laboratories.
Features:
Using high quality nitrile butadiene rubber with other additives, refined processing; No protein, no allergic reaction to human skin; Non-toxic, harmless; Strong and durable, good adhesion.
Scope of Application:
Household work, electronics, chemical, aquaculture, glass, food and other factory protection, hospital, scientific research and other industries.
News report: In order to prevent the use of gloves to slip, improve the use of comfort, anti-cutting gloves palm was dipped in glue treatment, according to the different dipping gel, divided into latex, nitrile and polyurethane three kinds. Among them, polyurethane gloves have thin colloid, which is generally used in horticulture and electronics industries with relatively high sensitivity requirements. Latex gloves and nitrile gloves are relatively thick colloid, latex gloves have better anti-skid performance, nitrile gloves have better anti-oil performance, suitable for machining, logistics handling, oil depot operations, etc.
