Features radiation resistance, insulation and stability, hydrolysis, pressure, corrosion, conforming materials into mechanical parts with self-lubricating effect. . Temperature, good thermal stability, high heat resistance (compared with PPS fine), HDT at 315 degrees Celsius, UL continuous use temperature of 250 degrees Celsius. 1: Mechanical properties of PEEK is between toughness and rigidity and balance of plastic. Particularly its excellent alternating stress fatigue resistance is the most outstanding of all plastics can be comparable with the alloy material. 2: Self-lubricating PEEK has outstanding sliding characteristics in all plastics, suitable for the stringent requirements of low coefficient of friction and resistance to abrasion purposes. In particular, carbon fiber, graphite mixing proportion of each modified PEEK self-lubricating properties better. 3: chemical resistance (corrosion resistance) PEEK has excellent chemical resistance in ordinary chemicals, can be dissolved or damaged only concentrated sulfuric acid, its corrosion resistance and nickel steel similar. 4: flame retardant polymer PEEK is very stable, 1.45mm thick sample, without any flame retardant can achieve the highest standards. 5: peeling resistance PEEK excellent peeling resistance, it can be made of or coated with a thin wire, can be used in harsh conditions. 6: fatigue resistance PEEK has the best fatigue resistance in all resin. 7: Radiation resistance capability is strong resistance to high radiation than the best general-purpose polystyrene resin in radiation resistance. It can still maintain high performance made good insulating ability of 1100Mrad when γ radiation dose. 8: Hydrolysis of PEEK and its composites from chemical influence of water and high-pressure steam, products made of this material for use in high temperature and high pressure water continuously maintain the outstanding characteristics. Features PEEK PEEK (poly ether ether ketone) Plastics is an aromatic crystalline thermoplastic polymer material having a melting point of 334 ℃, with high mechanical strength, high temperature, impact resistance, flame retardant, acid, hydrolysis resistance, wear resistance, fatigue resistance to radiation and good electrical properties. High temperature PEEK resin has a high melting point (343 ℃) and a glass transition temperature (1 43 ℃), the continuous use temperature of 260 ℃, its 30% GF or CF-reinforced grades of load heat distortion temperature up to 316 ℃.
