Characteristics of nitrile gloves
Unlike latex gloves, nitrile gloves are insoluble in non-polar solvents, (can effectively withstand alkane, cycloalkane non-polar reagents, 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, degradation grade P, the overall grade of degradation and penetration of gloves is marked in red. In toluene, degradation grade F, penetration time 34 minutes, permeability F, marked in yellow. In xylene, degradation grade G, permeation time 96 minutes, permeability F, marked in green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery Acid), 30% hydrogen peroxide, etc. are marked in green, degradation grade E, penetration time > 360 minutes. Methanol, ethanol, n-propanol, pentanol, cyclohexanol and other alcohols are also marked in green. Butyronitrile Gloves with poor protective performance against dimethylformamide, acetone, butanone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate are marked in red. Made of high-quality nitrile rubber with other additives, refined and processed; no protein, no allergic reaction to human skin; non-toxic and harmless; durable and good adhesion.
