Ethylene acrylate rubber compound
Fluorine compound rubber 2025-04-25
Product introduction:
Ethylene acrylate has excellent heat and chemical resistance. It can be used within -40℃~175℃, has excellent ozone resistance, aging resistance, good compression permanent deformation, and good tolerance to oils such as automotive transmission oil and engine oil, so it is widely used in automotive accessories.
