PEEK film uses its characteristics of less water absorption than polyimide (PI), good alkali resistance, acid resistance, high frequency resistance at high temperature, solder wire resistance, radiation resistance, etc., as an insulating layer of class H and class c Materials, commonly used as insulating film for motors, generator sets, transformers, power capacitors, etc., can be wrapped around printed circuit boards, carrier tapes, polymer materials (covered with PEEK, carbon fiber materials, and glass fiber layers). 〉, high temperature resistant and drug resistant endless belt, etc.
The polyether ether ketone widened film has a low grain size, and generally must be composited with raw materials such as glass fiber, carbon fiber material, and melamine chemical fiber. The independent polyether ether ketone film can be stretched and heat treated to improve the compressive strength and temperature resistance. The polyether ether ketone film that has been stretched and heat-treated has a melting point of 80°C higher than that of PET film, and has compressive strength similar to that of phenylene polyimide (PI) film, and has moisture and chemical resistance Stronger than Kapton.
