Brief introduction of Nitrile Gloves

Nitrile rubber 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 two properties of homopolymer. The butadiene component gives the copolymer elasticity and cold resistance, while the acrylonitrile component has strong polarity. The – CN group can make the copolymer have good chemical corrosion resistance, especially the oil resistance. Increasing the content of acrylonitrile in rubber can improve the oil resistance of rubber, but the elasticity and cold resistance will be reduced. The product has good oil resistance, high wear resistance and good heat resistance.

Different from latex gloves, nitrile gloves are not soluble in non-polar solvents, (they can effectively resist non-polar reagents such as n-pentane, n-hexane, cyclohexane, etc.) and most of these reagents are marked in green. It should be noted that for aromatics, the protective properties of nitrile gloves are quite different. For example, in benzene, degradation grade P, the overall grade of degradation and penetration of gloves is red. In toluene, degradation grade F, permeation time 34 minutes, permeability F, marking yellow. In xylene, degradation grade g, permeation time 96 minutes, permeability F, marking green.
