1,Glass fiber reinforced plastic covers adopts unsaturated polyester resin as matrix of fiber reinforced thermosetting composite material, also called regiment shape mould plastic (DMC), with pressure molding technology is made, is a kind of new environment-friendly power cover plate.
2,With high-temperature and high-pressure once moulding technology, the degree of polymerization, high density, good resistance to impact and tensile strength, have wear-resisting, corrosion resistant, rusty, non-pollution, free maintenance etc.
