This 36 - um - thick Polyester Release Film is specifically designed for use in the manufacturing process of Glass - Reinforced Plastic (GRP) pipelines. Its unique properties make it an essential component in ensuring the high - quality production of these pipelines. With excellent strength, it can withstand the pressures and forces exerted during the manufacturing steps. The film's strong yet flexible nature allows it to conform precisely to the shape of the pipeline molds. Its remarkable clarity ensures that there are no visual impairments or distortions that could potentially affect the quality inspection of the GRP pipelines. Moreover, being free of joint knots, it provides a smooth and continuous surface, which is crucial for the uniform curing and integrity of the GRP material, resulting in durable and reliable GRP pipeline.
Product Features
Excellent resistance to high and low temperatures
Good chemical resistance
Excellent mechanical and electrical performance
