PEEK poly (ether ketone) PolyetherEtherKetone\xd\1 \ 1. Good temperature resistance, thermal stability, ultra-high heat resistance (better than PPS), HDT above 315℃, UL continuous use temperature of 25℃. \xd\2. High mechanical strength such as impact resistance, wear resistance, creep resistance and fatigue resistance. \xd\3. The drug resistance (except concentrated sulfuric acid) and hot water resistance (above PPS and PES) are the best. \xd\4. Good gamma ray resistance, flame retardancy and extrusion processability. \xd\5. Under high temperature and high humidity, the electrical characteristics are excellent. \xd\6. Minimum smoke, radiation resistance. \xd\7. The price is high, which requires high-temperature molding and poor fluidity. \xd\8. Good toughness, strength and rigidity. \xd\9. Good flame resistance, no need to add flame retardant. \xd\1. Poor processability.
