INTRODUCTION
PEEK board, PEEK stick, PEEK tube PEEK high temperature resistant, high performance thermoplastic engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, resistance to hydrolysis performance;its light weight, good self-lubricating performance, because of its processing performance very good, can befilled with carbon fiber, molybdenum disulfide, further improve lubricating property and mechanical strength. The excellent performance of PEEK material is mainly manifested in the following aspects: 1 high temperature The glass transition temperature and the melting point of PEEK with high (334 ℃), this is it can be in one of the use of heat resistance requirements of the reliable application of reason. The heat deformation temperature up to 316 ℃, continuous use temperature is 260 ℃. 2 mechanical properties PEEK is both the toughness and rigidity and a balanced plastics. Especially it stresses on the alternatingexcellent resistance to fatigue is one of the most outstanding all plastic, alloy material with comparable. 3 self lubrication PEEK has a sliding characteristics superior in all plastics, suitable for the strict requirements of low coefficient of friction and abrasion use. Especially the carbon fiber, graphite each accounted for a certain proportion of modified PEEK self lubrication performance. 4 chemical resistance (resistance) PEEK has excellent chemical resistance, the chemicals in general, can dissolve or destroy it onlyconcentrated sulfuric acid, its corrosion resistance is similar with nickel steel. 5 flame retardant PEEK is very stable polymer, 1.45MM thick samples, without any flame retardant can reach the highest flame retardant standards. 6 peeling resistance PEEK peeling resistance is good, and therefore can be made into coated thin wire or wire, and can be used inharsh conditions. 7 fatigue resistance PEEK has the best fatigue resistance in all the resin. The 8 radiation resistance The ability of resistance to radiation is very strong, more than the best of irradiated polystyrene resinresistance in general. Can high performance wire as the irradiation dose of 1100Mrad can still maintain goodinsulating ability. 9 water solution PEEK and its composite material are not affected by chemical effects of water and high pressure steam,products made with this material in high temperature and high pressure water continuous use can still maintain excellent properties. |
