Information

PP is a semi-crystalline material. It is harder and has a higher melting point than PE (polyethylene). Many commercial PP materials are random copolymers with 1 to 4% ethylene or clamp copolymers with higher ethylene content. Copolymer PP materials have a low heat distortion temperature (100C), low transparency, low gloss, and low rigidity, but have stronger impact strength. The strength of PP increases with the increase of ethylene content. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance properties. PP does not have environmental stress cracking problems.

Cheapest Polypropylene film

Usually, PP is modified by adding glass fibers, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than that of PE-HD and other materials. Both homopolymer and copolymer PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it has no resistance to aromatic hydrocarbon (such as benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. PP does not still have oxidation resistance at high temperatures like PE.
