Polypropylene (PP) sheet extrusion is PP resin added with various functional additives is made by extrusion, pressing, cooling, cutting and other processes of plastic sheet.

PP plate is a kind of semi crystalline material. It is harder and has a higher melting point than PE. Since the PP temperature of the polymer type is higher than 0, the PP material is a non regular copolymer of ethylene and a higher ratio of ethylene content. The copolymer type PP material has a low thermal distortion temperature (100), low transparency, low gloss, low rigidity, but has a stronger impact strength. The strength of PP increases with the increase of ethylene content. PP's VEKA softening temperature is 150. Due to the high degree of crystallinity, the surface rigidity and scratch resistance of this material are very good.
