PEEK is a kind of heat-resistant, high performance thermoplastic special engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, and hydrolysis resistance properties etc.; it has a light proportion and self-lubricating properties. Guangzhou Engineering Plastics Industries (Group) Company, has studied and applied this material in many industries for many years. Due to very good processing properties, it can be filled with carbon fiber, Fiberglass and MoS2 etc. In order to improve lubrication performance and mechanical strength further.
