Introduction of PP Sheet :
PP is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP don't have the problem of environmental stress cracking. Moreover, it could offer significant resistance to any chemical or acid.
Typical Properties of PP Sheet :
-- Light weight
--Wear resistant
--Low water absorption
--Excellent impact resistance
--Excellent corrosion resistance
--Good chemical stability
--Non-toxic and tasteless
