FRP-GRP Films

BOPET Polyester Film for FRP/GRP Release Applications **BOPET (Biaxially Oriented Polyethylene Terephthalate) Polyester Film** is a high-performance release film used in **FRP (Fiber Reinforced Plastic) and GRP (Glass Reinforced Plastic)** manufacturing. Its excellent dimensional stability, smooth surface, mechanical strength, and controlled release characteristics make it ideal for composite molding and lamination processes. The film provides an effective **barrier and release layer between the composite material and mold/tooling surface**, helping achieve a smooth surface finish while reducing resin adhesion and facilitating easy demolding. **Available Film Thicknesses:** **12, 23, 36 and 50 micron**, with customized thicknesses available depending on application requirements. **Key Advantages:** * Excellent dimensional and thermal stability * Smooth and uniform surface * High tensile and mechanical strength * Controlled release properties * Good resistance to epoxy, polyester and vinyl ester resins * Low elongation and excellent handling characteristics * Consistent thickness and surface quality * Suitable for manual lay-up and vacuum infusion processes **Typical Applications:** FRP/GRP panels, wind-energy components, automotive parts, marine components, industrial composite structures, pipes, tanks, molds and other composite manufacturing applications. The film can be supplied in different **widths, thicknesses and surface treatments to meet specific FRP/GRP processing and release requirements.
