Good high temperature resistance oil resistance aging resistance cold resistance acrylate rubber HNBR compound
Description:
Acrylate rubber is an elastomer obtained by copolymerization of acrylic ester as the main monomer.
Due to its special structure, it has many excellent characteristics, such as: heat resistance, aging resistance, oil resistance, ozone resistance, ultraviolet resistance, etc.,
its mechanical properties and processing properties are better than fluorine rubber and silicone rubber, and its heat resistance, aging resistance and oil resistance Better than nitrile rubber.
ACM is widely used in various high-temperature and oil-resistant environments, and has become a sealing material that has been developed and promoted by the automotive industry in recent years, especially for high-temperature resistant oil seals, crankshafts, valve stems, cylinder gaskets, hydraulic oil pipelines, etc.
Application:
The application field of AEM is mainly auto parts.
Such as front and rear crankshaft oil seals, front and rear main shaft oil seals, power steering pump seals, rubber products.
Transmission pump seals, water pump seals, engine valve stem oil seals.
CVJ dust cover and power steering hose and 175℃ radiator hose.
Feature:
Good high temperature resistance, oil resistance, aging resistance, cold resistance,flex resistance, excellent mechanical properties.
AEM has excellent ozone resistance and good weather resistance.
AEM can be used continuously for 18 months at 120 degrees Celsius and for 6 weeks at 170 degrees Celsius.
The strength can be 15Mpa.
