China manufacturer cheap custom any size and material uhmw pe tubes100 mm pp polypropylene pipe

I. PP Description

PP looks like PE, but PP is more transparent, lighter. PP is flammable. PP own low water absorption, low gas permeability. PP has good mechanical properties, the tensile strength and yielding strength are better than PE, PS and ABS. PP resists stress cracking and easy to weld, but low notched impact strength, the finished parts shall avoid sharp corners and notches. The temperature ranges between +5°C and 100°C.
