PEEK is what material?What is the price of PEEK?

PEEK polyphenylene ether ether ketone (polydiethyl ether ketone) PolyetherEtherKetone\x0d\1. Temperature resistance, good thermal stability, ultra-high heat resistance (better than PPS), HDT at 315 ℃ or more, UL continuous use temperature of 250 ℃. \x0d\2.High mechanical strength such as impact resistance, abrasion resistance, latent change resistance, and fatigue resistance. \x0d\3. Drug resistance (except concentrated sulfuric acid), hot water resistance is the best (PPS, PES and above). \x0d\4. Excellent gamma ray resistance, flame retardant, and extrusion processability. \x0d\5. Excellent electrical characteristics at high temperature and high humidity. \x0d\6. Minimized smoke generation, radiation resistant. \x0d\7. High price, high temperature molding, poor flowability. \x0d\8. Excellent toughness, strength and rigidity. \x0d\9. Good flame resistance, no need to add flame retardant. \x0d\10. Poor processability.
