EPP是以聚丙烯为连续相,气体为分散相的聚丙烯/气体两相复合材料。可通过气体改变聚合物相的形态、结构,使之具有质轻、优异的力学性能、耐热、回弹性优等特性。
EPP is a polypropylene/gas two-phase composite material with polypropylene as the continuous phase and gas as the dispersed phase. The morphology and structure of polymer phases can be altered by gas, resulting in lightweight, excellent mechanical properties, heat resistance, and superior resilience.
