High temperature resistant PEEK

characteristic

1 Good high temperature resistance, high glass transition temperature (Tg=143°C) and melting point (Tm=343°C), thermal deformation temperature under load reaches 316°C, and instantaneous use temperature can reach 300°C.

2 In terms of mechanical properties, it has both rigidity and flexibility, and has excellent fatigue resistance under alternating stress, which is comparable to alloy materials.

3 Excellent self-lubricity and excellent sliding performance, suitable for low friction coefficient and wear-resistant scenarios.

4 Excellent corrosion resistance, except concentrated sulfuric acid, is insoluble in any solvent and strong acid and alkali, is resistant to hydrolysis and has high chemical stability.

5 In terms of flame retardant, you can reach the UL standard 94V-0 level without adding flame retardant.

6 The materials are easy to process, have good high temperature fluidity and high thermal decomposition temperature. They can be processed through injection molding, extrusion, compression molding, melt spinning and other methods.

7 Excellent anti-peeling performance, can be made into thin-coated wires or electromagnetic wires, suitable for harsh environments.

8The best fatigue resistance among all resins.

9 It has strong resistance to high energy radiation, exceeding the polystyrene with the best radiation resistance among ordinary resins, and can still maintain good insulation when the radiation dose reaches 1100Mrad.

10. Good hydrolysis resistance, PEEK and its composite materials are not affected by water and high-pressure water vapor, and can maintain excellent performance in continuous use in high-temperature and high-pressure water environments.

11 The amount of smoke emitted in plastic materials is low.

12. Decomposition at high temperature mainly produces carbon dioxide and carbon monoxide, complies with the British aviation test standard BSS 7239 (detected after 100 grams of sample is completely burned), PEEK450G toxicity index is 0.22, and there is no acid gas release.

13. Good electrical insulation, stable in a wide temperature range, and small dielectric loss under high frequency conditions.
