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.

Besides, PEEK can be used to produce some exact medical equipments for the OPS and dentistry, which can annihilate
bacterium and can be used time after time, the most important application of PEEK, which is used to produce the
artificial bone instead of metal. The artificial bone, which is made of PEEK, has the good performance of light-weight,
non-toxic and good-chemical-resistance and so on, and can integrate with the organism of human body. So PEEK is
also successfully applied in medical industries
