Characters and Applications CMPPG30/CMPPG30W, the graft-modified Polypropylene with glass-fiber, are new products which exhibit much better mechanical and thermal properties than the general GF reinforced PP. At the same time, because of their high processing performances, they could mould the bulk thin-wall parts as well as complicated components. The products are mainly used to produce car cooling fan and fan shroud, car dash board, air filter, trailblazer casing, wave-wheel for washing machine and so on.
