Product description:
Acrylate rubber referred to as "ACM, predominantly acrylate monomers by copolymerization of elastomer, its main chain is saturated carbon chain, side base for polar ester base.Special structure to endow them with many excellent characteristics, such as heat resistance, ageing resistance, oil resistance, ozone resistance, resistance to ultraviolet radiation and other performance;Mechanical properties and processing performance is better than that of fluoro rubber and silicone rubber;The heat oxygen aging and oil resistance than NBR.
