Polyolefin elastomer (polyolefinelastomer, POE) mainly refers to ethylene and α-olefin (1-butene, 1-hexene, 1-octene, etc.) of the random copolymer elastomer. It has excellent weather resistance and chemical resistance, as well as good transparency and flexibility, good compatibility with polyolefins, both the high elasticity of rubber and plastic easy processing advantages, and obtain the elasticity of the lower cost, lighter weight, lower energy consumption, and more friendly to the environment.
