1. Appearance: The surface of the film is flat and smooth, and there should be no defects such as wrinkles, tearing, granules, bubbles, pinhole and external impurities. The edges are neat and damaged.
2. Width and length: thin film rolls or plate supply. Width is 10-620mm. According to user requirements, the width and length are determined by both the supply and demand parties and can be used for the belt.
3. Thickness and allowable deviation.
Polybamine thin film is a H -level insulating film produced by "drooling method" produced by "saliva" in high polar solvents in high pole solvents. It has excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, aggressive resistance, chemical stability and flame retardability.
Polybamine thin film production is used for various traction motors, oil motors, nuclear power equipment, high -temperature wire -resistant wires and cables, electromagnetic wires, special electrical appliances, anti -virus masks, high -temperature -resistant printing circuit base materials, flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits and flat circuits The speakers' sound rings skeleton and other fields are the only polypelide film used in the domestic cutting.
