Introduction To Nitrile Gloves

Nitrile rubber is made 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 homopolymers. The butadiene component gives the copolymer elasticity and cold resistance, the acrylonitrile component has strong polarity, and the -CN group can make the copolymer have good chemical corrosion resistance, especially oil resistance (referring to alkane oil)
Nitrile gloves can be divided into powdered and powder-free. Nitrile gloves are available in two lengths: 23cm and 30cm; thickness is 0.08~0.09mm, the color is mainly blue, and the main finished product packaging is 100pcs per box, with specifications of XS, S, M, L, XL.
Combined with the "Ansell Glove Permeation/Degradation Protection Guide", discuss the applicability of gloves. Note that the "Glove Protection Guide" lists the degradation and permeation data of gloves. The first square in each column uses three different color coding methods to indicate the overall degradation and permeation level of each glove. Green means that the gloves are very suitable for use with the chemical; yellow means that the gloves should be used with caution; red means that the gloves are prohibited from being used with the chemical. Capital letters represent grades. E: Excellent; VG: Very good; G: Good; F: General; P: Poor; NR: Not recommended.
Unlike latex gloves, nitrile gloves are insoluble in non-polar solvents (they can effectively withstand non-polar reagents such as alkanes and cycloalkanes, such as n-pentane, n-hexane, cyclohexane, etc. Most of these reagents are marked in green. It should be noted that for aromatic hydrocarbons, the protective performance of nitrile gloves varies greatly. For example, in benzene, the degradation level is P, and the overall degradation and penetration level of the gloves is marked in red. In toluene, the degradation level is F, the penetration time is 34 minutes, and the penetration rate is F, which is marked in yellow. In xylene, the degradation level is G, the penetration time is 96 minutes, and the penetration rate is F. , marked in green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery acid), 30% hydrogen peroxide, etc. are all marked in green, with degradation level E and penetration time >360 minutes. Methanol, ethanol, n-propanol, amyl alcohol, cyclohexanol and other alcohols are also marked in green. Nitrile gloves have poor protection against dimethylformamide, acetone, butanone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate, or have no protection, and are all marked in red.
Nitrile gloves are a type of protective gloves commonly used in laboratories.
