25μm Polyester Release Film for GRP Pipeline Manufacturing - 150 MPa Tensile Strength, 180°C Temperature Resistance
Specialized ultra-clear polyester film designed specifically for glass-reinforced plastic pipeline production, ensuring smooth surfaces and optimal curing results.
This 25μm thick polyester release film is engineered for glass-reinforced plastic (GRP) pipeline manufacturing processes. The film provides exceptional strength to withstand manufacturing pressures while maintaining flexibility to conform precisely to pipeline molds. Its ultra-clear properties eliminate visual impairments that could affect quality inspection, and the joint-knot-free surface ensures uniform curing for durable, reliable GRP pipelines.
- Excellent resistance to high and low temperatures
- Superior chemical resistance properties
- Outstanding mechanical and electrical performance
- Excellent flatness with low friction coefficient
- Bubble-free surface for uniform curing
Widely used for mold demolding and surface smoothing in fiberglass pipeline and storage tank production. Optional silicone oil coating available for enhanced demolding efficiency.
