What is the degradation guide for nitrile gloves?
Nitrile rubber is produced 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 homopolymers. performance. The butadiene component imparts elasticity and cold resistance to the copolymer, the acrylonitrile component has strong polarity, and the -CN group can make the copolymer have good chemical resistance, especially the oil resistance (referring to alkane oil). Increasing the content of acrylonitrile in the rubber can improve the oil resistance of the rubber, but the elasticity and cold resistance will be reduced. Its products have good oil resistance, higher abrasion resistance and better heat resistance.
In conjunction with “Ansell Glove Permeation/Degradation Protection Guide”, discuss the suitability of gloves. Note that the “Guide to Glove Protection” lists the degradation and penetration data of gloves. The first square in each column uses three different color coding methods to indicate the overall level of degradation and penetration of each glove. Green means that the glove is very suitable for use with the chemical; yellow means that the glove should be used carefully in the application; red means that it is forbidden to use the glove with the chemical. Capital letters represent grades. E: excellent; VG: very good; G: good; F: fair; P: poor; NR: not recommended.
