汽车风雨密封条主要由乙烯-丙烯-二烯烃三元共聚物(EPDM)制得。EPDM在这些应用中成为所选聚合物是因为它具有优异的耐侯性、耐臭氧渗透性、高抗氧化性和耐高温性,以及高度延伸后而不失去其物理性能和机械性能的性质。 Automotive weather seals are mainly made of ethylene-propylene-diene terpolymer (EPDM). EPDM is the polymer of choice in these applications because of its excellent weatherability, ozone resistance, high resistance to oxidation and high temperature resistance, as well as its high degree of elongation without losing its physical and mechanical properties.
