Nitrile Examination Gloves: Introduction to Nitrile Gloves

Nitrile Examination Gloves Nitrile rubber is made by emulsion polymerization of butadiene (H2C=CH-CH=CH2) and acrylonitrile (H2C=CH-CN), mainly by low-temperature emulsion polymerization, with two homopolymers Nature. The butadiene component gives the copolymer elasticity and cold resistance, the acrylonitrile component is strong, and the -CN group can make the copolymer have good chemical resistance, especially oil resistance. Increasing the content of acrylonitrile in the rubber can improve the oil resistance of the rubber, but the elasticity and cold resistance will decrease. The product has good oil resistance, high abrasion resistance and good heat resistance.

Introduction of Nitrile Gloves recommended by:

 

Nitrile gloves can be divided into powder gloves and powder-free gloves. The length of the nitrile gloves is 23 cm and 30 cm. The thickness is 0.08~0.09mm, and the color is mainly blue. The main finished products are packed in 100 packages per carton, and the specifications are XS, S, M, L, XL.

Examination Gloves Combining with the “Guidelines for Ansel Gloves Permeation/Degradation Protection“, the suitability of gloves was discussed. Please note that the “Glove Protection Guide” lists the degradation and penetration data of gloves. A square in each column shows the overall degradation and penetration level of each glove in three different color coding methods. Green means that the gloves are very suitable for use with chemicals; yellow means that the gloves should be used with care; red means that the use of gloves with chemicals is prohibited. Capital letters represent grades. e: excellent; VG: very good; g: good; f: fair; p: poor; NR: not recommended.

 

Different from latex gloves, nitrile gloves are insoluble in non-polar solvents and can effectively withstand alkane, cycloalkane and other non-polar reagents, such as n-pentane, n-hexane, cyclohexane, etc., mostly green. It should be noted that for aromatic hydrocarbons, the protective properties of nitrile gloves vary greatly. For example, in benzene, the degradation level is P, and the overall level of glove degradation and penetration is marked in red. In toluene, degradation grade f, penetration time 34 minutes, permeability f, marked as yellow.

In xylene, the degradation grade is g, the penetration time is 96 minutes, the penetration rate is f, and the mark is green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (acid for battery), 30% hydrogen peroxide, etc. The mark is green, the degradation grade is E, and the penetration time is 360 minutes. Alcohols such as methanol, ethanol, n-propanol, pentanol, and cyclohexanol are also marked in green. Nitrile gloves have poor or no protection against dimethylformamide, acetone, methyl ethyl ketone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate. They are all marked in red.
