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.
