Does PP plastic board have thermal expansion and cold contraction?
It is harder than PE and has a higher melting point. Since the PP temperature of homopolymer is more than 0 degrees Celsius, it is very brittle, so many commercial PP materials are random copolymers of 1~4% ethylene or block copolymers with higher ratio of ethylene content.
Copolymer type PP material has lower thermal distortion temperature (100 DEG C), low transparency, low gloss and low rigidity, but has stronger impact strength.
PP plastic board does not heat up and contract coldPolypropylene (PP) extrusion plate is a kind of plastic sheet made by adding PP resin and adding various functional auxiliaries to extrusion, calendering, cooling and cutting. PP plate is a semi crystalline material.
