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. Guandong 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 and MoS2 etc. to improve lubrication performance and mechanical strength further.
