PEEK Polyetheretherketone Thin Film Key Properties

The PEEK film manufactured by thermoplastic molding of the super engineering plastic PEEK resin is divided into two types: low crystallization and high crystallization. PEEK film has the following remarkable characteristics:

1. Mechanical properties: It is a plastic film that has both toughness and rigidity and is balanced, especially its excellent fatigue resistance to alternating stress is outstanding among all plastics, comparable to alloy materials.

2. High temperature resistance: It can withstand the temperature of lead-free soldering process, the film thickness is between 25-155 microns, the RTI grade for non-impact mechanical applications is 220°C, and the electrical application is 200°C, and the carbonization point remains at 500°C Stablize.

3. Self-lubrication: It has outstanding sliding properties among all plastic films, and is suitable for applications that strictly require low friction coefficient and wear resistance, especially the PEEK film with carbon fiber and graphite mixed and modified in a certain proportion has better self-lubrication performance .

4. Chemical resistance (corrosion resistance): It has excellent chemical resistance. Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.

5. Flame retardancy: Very stable polymer, without adding any flame retardant, can reach the highest flame retardant standard, halogen-free, in line with IEC 61249-2-21 standard.

6. Stripping resistance: The stripping resistance is very good, and it can be made into thin-coated electromagnetic wires, and can be used under harsh conditions.

7. Fatigue resistance: better fatigue resistance among all resin films.

8. Radiation resistance: the ability to withstand high radiation is very strong, and it can still maintain good insulation ability under ultra-high radiation dose.

9. Hydrolysis resistance: It is not affected by water and high-pressure water vapor. Products made of this film material can still maintain excellent characteristics in continuous use in high-temperature and high-pressure water.

10. Melting processability: fusion with metal when the temperature is above the melting point, easy ultrasonic sealing (PET film can also be sealed), laser can be melted and printed.

11. High sound clarity: avoid the "hearing fatigue" caused by the noise of the metal film, and achieve better acoustic performance.

12. Environmental protection and safety: light weight, recyclable, compliant with RoHS standards, can be used to manufacture products that meet the requirements of the same directive, and meet the requirements of the US Food and Drug Administration (FDA).

13. Wide range of thickness options: films with a thickness of only 3 microns to 150 microns can be produced.
