一、性能与组成丙烯酸酯橡胶简称ACM,是以丙烯酸酯为主单体经共聚而得的弹性体,其主链为饱和碳链,侧基为极性酯基。特殊的结构赋予其许多优异的特点,如耐热、耐老化、耐油、耐臭氧、抗紫外线等性能,力学性能和加工性能优于氟橡胶和硅橡胶;其耐热氧老化性和耐油性优于丁腈橡胶。被广泛应用于各种高温、耐油环境中,成为近年来汽车工业着重开发推广的一种密封材料,目前国内需求几乎全部依赖进口。 First, the performance and composition Acrylate rubber, referred to as ACM, is based on acrylate monomer obtained by copolymerization of the elastomer, the main chain of saturated carbon chain, pendant polar ester group. Special structure gives many excellent features, such as heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance and other properties, mechanical properties and processing performance superior to fluorine rubber and silicone rubber; its thermal aging resistance and oil resistance excellent In nitrile rubber. It has been widely used in various high temperature and oil resistant environments and has become a kind of sealing material that the automobile industry focuses on developing and popularizing in recent years. At present, domestic demand is almost totally dependent on imports.
