frp cover

Product introduction:

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.

 

Product features:
1,Internal use mesh reinforced enhancement, key mechanical parts, special strengthen occurred in the inevitable external shocks, can quickly dispersed pressure guarantor car safety.
2,Products: the optimal design of the stress of the posterior special skeleton, special strengthen key positions.
3,Advanced structure, light weight, appearance generous, flawless, without delaminates, without bending deformation, prevent channeling move, safe in operation and convenient.
4,High precision: this product bases, cover small clearances, occlusive close, overcoming the similar products running, jumping, ring, etc.
