Polyetheretherketone is a polymer composed of repeating units with one ketone bond and two ether bonds in its main chain structure. It belongs to special high-molecular materials. It possesses outstanding physical and chemical properties such as high temperature resistance and resistance to chemical corrosion, and is a type of semi-crystalline high-molecular material.

In 2020, in order to fill the gap in domestic high-end special engineering plastic films and address the situation where the relevant industries were dependent on foreign countries for their supplies, our company increased its investment. We imported the first PEEK film production line from abroad and dedicated it to the research and manufacturing of special high-temperature resistant engineering plastic films. The production line was officially put into operation in July 2021.

The PEEK film is a semi-crystalline, high-performance special film made from PEEK polymer. It has excellent heat resistance, light weight, superior mechanical properties and durability, outstanding radiation resistance, hydrolysis resistance, chemical resistance, excellent electrical insulation performance, excellent wear resistance, good barrier properties and flame retardancy, low toxicity of combustion products, low water absorption rate, halogen-free, and good processing performance.

PEEK film is primarily used in electrical insulation materials, pressure-sensitive adhesive tapes, printed circuit board substrates, high-temperature labels, high-speed motor pads, aviation insulation materials, pressure sensor diaphragms, acoustic loudspeaker diaphragms, and more.
