PEEK film is a high-performance thermoplastic film that leads the future development trend of film performance, featuring high-temperature resistance, radiation resistance, hydrolysis resistance, electrical insulation, and barrier properties, among others. Its combustion products have almost no toxic emissions. The balanced performance makes it one of the films with the highest performance and the widest application in the market.

Specific physical properties of PEEK film:
(1) Heat resistance: It is a high-temperature resistant thermoplastic film with a melting point of 343°C and a long-term service temperature of 260°C as recognized by UL in the United States.
(2) Flexibility: It ranks among the top of the currently available high-temperature resistant films on the market, outperforming polyimide and polyphenylene sulfide films.
(3) Solvent resistance: It is insoluble in most acid and alkali solvents.
(4) Hydrolysis resistance: It can be used for a long time under 200°C steam.
(5) Radiation resistance: It has excellent resistance to various radiations and can withstand high-dose gamma rays without changing its physical properties.
(6) Dimensional stability: It has extremely low water absorption and a low linear thermal expansion coefficient.
(7) Wear resistance: Taber H10 wheel abrasion loss is 0.00027.
(8) Flame retardancy: PEEK film of a certain thickness has self-extinguishing properties, and its combustion products are low in smoke and non-toxic.
(9) Excellent electrical and insulating properties: It maintains excellent insulation and stable electrical properties under high temperature, high pressure, high frequency, high speed, and high humidity conditions.
