General Compounds

Acrylate rubber (hereinafter abbreviated as ACM) is an elastomer obtained by copolymerizing an acrylate-based monomer, and its main chain is a saturated carbon chain, and its side group is a polar ester group. Due to its special structure, it has many excellent characteristics, such as heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc. Its mechanical properties and processing properties are superior to those of fluororubber 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. It has become a kind of sealing material developed and promoted in the automotive industry in recent years, especially for high temperature oil seals, crankshafts, valve stems, cylinder head gaskets and hydraulic oil pipelines.

Ethylene acrylic elastomers(hereinafter abbreviated as AEM) is an excellent low compression rubber with excellent resistance to high temperatures, heat resistant mineral oils, fluids and weathers. The low temperature elasticity and mechanical properties are superior to ACM, but the properties of low aniline resistant oil (same as ASTM NO. 3 oil) and polar solvent resistance are not good.
