Basic Classification Knowledge Of Nitrile Rubber

2022-05-21

Butadiene-acrylonitrilecubber is a copolymer of butadiene and acrylonitrile obtained by emulsion polymerization, called butadiene-propylene cross rubber, referred to as butadiene rubber, code-named NBR. Nitrile rubber, there are two kinds of high temperature emulsion polymerization (25-50 ℃) and low temperature emulsion polymerization (5-20 ℃). At present, low temperature emulsion polymerization is mainly adopted. Nitrile rubber is known for its excellent oil resistance. As an oil-rubber, it is widely used in the manufacture of oil-resistant products such as hoses, tapes, capsules, sealing products, gaskets, etc. In addition, it also has the characteristics of aging resistance, wear resistance, low air permeability and high cohesion.

Nitrile rubber is divided into general nitrile rubber and special nitrile rubber according to the scope of application. General-purpose nitrile rubber mainly refers to butadiene-acrylonitrile binary copolymer, which is widely used. Special nitrile rubbers include terpolymers that introduce third monomers such as hydroxynitrile, poly-stabilized nitrile rubber, partially cross-linked nitrile rubber, nitrile rubber, hydrogenated nitrile rubber, nitrile rubber and polychloroethylene Ethylene blends as well as liquid rubber and powder rubber, etc.
