polypropylene (PP)


1. Translucent, rigid and tough. High bending strength, fatigue resistance and stress crack resistance;

2. Light weight, non-toxic, tasteless, high temperature resistance and good insulation.


1. It is easy to become brittle below 0℃and difficult to join;

2. Poor weather resistance, easily decomposed by ultraviolet rays, and easily oxidized;

3. Large shrinkage rate (1%-3%) and poor dimensional stability, so it is not suitable for making high-precision parts.


Chemical containers, washbasins, pipes, pump impellers, joints, ropes, straps, transparent bottles, insulating materials, auto parts.
