l Product performance characteristics

PEEK film is an unfilled semi-crystalline film made of polymer. Here is the performance characteristics:

1.High purity, good stability, light weight, high mechanical strength.

2. Radiation resistance, hydrolysis resistance and extensive chemical resistance: insoluble in all common solvents-excellent resistance to acids, alkalis, lubricants and automotive fluids.

3. Excellent heat resistance: the relative thermal index is 220 ℃, which is available in the processing of lead-free solder up to 300 ℃

4. Excellent abrasion resistance: more than 3 times abrasion resistance than PI and PTFE, and the ultimate pressure speed under non-lubricated condition is 145MPa-m / min

5.Excellent barrier performance and low moisture absorption performance.

6. Excellent sound absorption properties: Unparalleled anti-noise fatigue performance, can withstand higher output power.

7. Excellent electrical insulation performance: high dielectric strength, stable dielectric performance under various temperature, frequency and temperature conditions.

8. Lightweight and good flame retardancy; high flame retardancy without using flame retardant additives

9. Inherently halogen free

10. Easy to process – can be  laminated to other materials, thermoformed, metallised, coated, printed, stamped and die cut, welded and heat sealed and coated.
