The PEEK film has high temperature performance, good mechanicalstrength，radiation, hydrolysis and chemical resistance，electrical insulation,abrasionresistance, excellent barrier properties , good flammability resistance, and low moisture absorption. Inherently halogen-free and ease of processing. The applications of PEEK films include electrical insulation，pressure sensitive tapes，printed circuit substrates，high temperature labels，washers in high speed motors，aerospace insulation,pressure sensor membranes，acoustic speaker diaphragms.

Physical properties

(1) Heat resistance: high temperature resistant thermoplastic film, melting point is 343 ℃, long-term use temperature recognized by UL is 260 ℃.

(2) Excellent electrical and insulation properties: it still has excellent insulation and stable electrical properties under high temperature, high pressure, high frequency, high speed, high humidity conditions.

(3) Flexibility: It currently ranks among the best in the market high-temperature resistant film products, better than polyimide and polyphenylene sulfide films.

(4) Solvent resistance: insoluble in most acid and alkali solvents.

(5) Hydrolysis resistance: It can be used for a long time under 200℃ water vapor conditions.

(6) Radiation resistance: It has excellent resistance to various kinds of radiation, and can withstand high doses of gamma rays without changing physical properties.

(7) Dimensional stability: extremely low water absorption and linear thermal expansion coefficient

(8) Wear resistance: TaberH10 wheel wear is 0.00027.

(9) Flame retardancy: PEEK film with a certain thickness is self-flame retardant, and its combustion products are low-smoke and non-toxic.
