![]() It has excellent wear resistance, even if the unmodified pure resin PEEK still has good self-lubricity. PEEK is a wear-resistant grade modified by graphite, PTFE, molybdenum disulfide, etc. It is widely used in high-voltage electrical fields. The surface resistivity of PEEK is better than conventional thermoplastic materials such as PTFE, PET, PI, etc. At 150 ℃ to room temperature, PEEK volume resistivity is little affected by temperature. PEEK material has good electrical insulation. During high temperature decomposition, carbon dioxide and carbon monoxide are mainly produced, and the content is very small. ![]() The natural color of PEEK is flame retardant, and it can reach UL94-V0 level without adding any flame retardant. After 100,000 hours of continuous use at high temperatures, PEEK performance can still maintain 50% of normal temperature. The thermal deformation temperature of PEEK is higher than that of PPS, and the continuous use temperature of PEEK is 250 ℃. However, because PEEK is a semi-crystalline material, PEEK can still maintain good mechanical properties in the range close to the melting point temperature. PEEK has a glass transition temperature of 143 ° C and a melting point of 343 ° C. At high temperature, the bending strength, creep resistance and compressive strength of PEEK materials have good performance, and the impact resistance at room temperature is better than polyimide PI, PPS, PAI and other materials. As the temperature rises, PEEK can still maintain very stable tensile strength in a large temperature range. ![]() The tensile properties of PEEK materials are better than most thermoplastic materials. In recent years, with the introduction of domestic PEEK raw materials, the price of raw materials has been reduced, and they have been widely used in more and more industries. Poly-ether-ether-ketone ( PEEK) is a thermoplastic special engineering plastic with excellent performance in abrasion resistance, temperature resistance, corrosion resistance, etc., which can meet various complex Material requirements of parts and components under working conditions and harsh environments.
