Polyether Ether Ketone

Description

PEEK, short for Polyether Ether Ketone, is a high-performance specialty engineering plastic with outstanding advantages such as high-temperature resistance, chemical resistance, high mechanical strength, and good self-lubrication. It operates stably under harsh conditions. Its long-term service temperature can reach 260°C, with short-term resistance exceeding 300°C, while maintaining good mechanical properties at high temperatures. 2. Excellent chemical resistance: Stable against most chemical media like acids, alkalis, and organic solvents; it only degrades in strong oxidizing acids like concentrated sulfuric acid. It exhibits excellent tensile strength, flexural strength, and fatigue resistance, along with strong impact resistance and good dimensional stability, resisting deformation. Its low friction coefficient allows for low-wear operation without additional lubrication, making it suitable for wear-resistant moving parts. Medical-grade PEEK is non-toxic and non-teratogenic, suitable for implantable medical devices; it also withstands gamma and UV radiation, offering excellent weatherability. Applications include aerospace components, automotive engine parts...
