Talc powder is a crucial component in FRP composites, offering distinct advantages such as purity, moisture resistance, and extended shelf life. The inherent shrinkage of the resin in FRP can be mitigated by incorporating talc powder, which diminishes resin heat generation, resulting in reduced deformation and shrinkage. Its widespread application encompasses FRP filler material, FRP molding, and fiberglass filler material.
