Properties affected by the nitrile rubber content of acrylonitrile, the acrylonitrile content increases as the tensile strength, heat resistance, oil resistance, air tightness, hardness, but the flexibility, cold resistance is reduced. Nitrile rubber is poor ozone resistance and electrical insulation properties. Preferred polar water resistance of nitrile rubber is very strong, and the compatibility of the other polymer is generally not very good, but, and chloroprene rubber, modified phenolic resins, polyvinyl chloride and other highly polar polymers, especially and chlorine-containing polymer has good compatibility, and is usually carried out by. In addition, to improve the processing and use of performance, nitrile rubber is also often associated with natural rubber, styrene-butadiene rubber, polybutadiene rubber and other non-polar rubber and use.
Nitrile rubber is mainly used for the production of oil products, such as oil pipe, tape, rubber diaphragm and large oil bag, commonly used in the production of various types of oil molded products, such as O-rings, seals, cups, diaphragms, valves, bellows , but also for the production of plastic sheet and wear parts.
