以均聚pp为主要原料，共聚pp、HDPE、SBS为改性剂，用挤出共混法研制蓄电池用共混改性PP塑料。

Blending modified PP for accumulator was developed by extrusion blending, with PP homopolymer as basic material, PP copolymer, HDPE and SBS as modifiers.

对于共聚pp，基体材料中的填充粒子的脱粘和橡胶粒子的空化使塑料破坏更加容易，从而降低了耐刮擦性。

Debonding of reinforced particles from the matrix and cavitation of rubber particles, in the case of co-PP, ease plastic deformation and thus, reduce the scratch resistance.
