Nitrile rubber is made from butadiene (H2C = CH-CH = CH2) and acrylonitrile (H2C = CH-CN) by emulsion polymerization. It is mainly produced by low-temperature emulsion polymerization with two homopolymers. performance. The butadiene component gives the copolymer elasticity and cold resistance. The acrylonitrile component has strong polarity. The -CN group can make the copolymer have good chemical resistance, especially oil resistance (referred to as paraffinic 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, high wear resistance and good heat resistance. [1-2]
Nitrile gloves can be divided into powdered and powder-free. Nitrile gloves are available in lengths of 23cm and 30cm; the thickness is 0.08 ~ 0.09mm, the color is mainly blue, the main finished product packaging is 100pcs per box, and the specifications are XS, S, M, L, XL. [1]
Discuss the suitability of gloves in conjunction with the "Guide to Ansell Gloves Penetration / Degradation Protection". Note that the “Glove Protection Guide” lists the degradation and penetration data for gloves. The first square in each column uses three different color coding methods to indicate the overall degradation and penetration level of each glove. Green indicates that the glove is very suitable for use with the chemical; yellow indicates that the glove should be carefully used in the application; red indicates that the glove is not allowed to be used with the chemical. Capital letters represent grades. E: Very good; VG: Very good; G: Good; F: Fair; P: Poor; NR: Not recommended. [2]
Unlike latex gloves, nitrile gloves are insoluble in non-polar solvents, (can effectively tolerate alkane, cycloalkane non-polar reagents, such as n-pentane, n-hexane, cyclohexane, etc. Most of these reagents are marked as green It should be noted that for aromatic hydrocarbons, the protection performance of nitrile gloves is quite different. For example, in benzene, the degradation level P, the overall degradation and penetration of the gloves are marked as red. In toluene, the degradation level F, the penetration time 34 minutes, permeability F, marked yellow. In xylene, degradation grade G, penetration time 96 minutes, permeability F, marked green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery Use acid), 30% hydrogen peroxide, etc. are marked as green, degradation level E, penetration time> 360 minutes. Methanol, ethanol, n-propanol, pentanol, cyclohexanol and other alcohols are also marked as green. Butyronitrile Gloves are marked with red for protection against dimethylformamide, acetone, methyl ethyl ketone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, ethyl acetate, or no protection.

Nitrile gloves are a type of protective gloves commonly used in laboratories.
