GRP(SMC) Sheet
1. GRP Composition Requisites
GRP, Glass fiber Reinforced Plastic, is a composite material that is obtained by mixing thermoplastic low shrinking agent, dispersant,
internal mold releasing agent, hardening agent, filler, pigment, thickener with thermosetting unsaturated polyester resin to produce compound, which will then be mixed with glass fiber stiffener and chemically increasing its property to produce GRP.
2. Property of GRP and its benefit
1) GRP is not only non-adhesive, simple to work with, but it is also clean.
2) GRP can be mounted on high temperature molds, and through high pressure from large hydraulic press,
it can produce products with subtle surface and high strength.
3) GRP has constant length of glass fiber contents, l-inch fiber, uniform mechanical strength, and high fallibility and fluidity.
4) Surface of GRP is smooth and graceful, and GRP can shorten finishing procedure as it has excellent coating.
5) GRP can easily correct deformities with rib, boss, and insert unlike the traditional use of RFP.
6) GRP can form molds with different thicknesses and has high mechanical strenght.
