PP board
PP is a semi crystalline material. It is harder than PE and has a higher melting point. Because of the type of PP homopolymer temperature higher than 0 ¡æ very brittle, so many commercial PP materials is clamp copolymer ethylene random copolymer with 1~4% or higher ratio of ethylene content. Copolymer type PP materials with low thermal distortions of temperature (100 ¡æ), low transparency, low gloss, low rigidity, but the impact strength is stronger. The PP intensity increases with the increase of ethylene content.
