Because of the limitations of general engineering plastics, some special applications (high temperature resistance, acid and alkali corrosion resistance, chemical resistance, etc.) can not meet the requirements of use. PEEK, a special engineering plastic, was used for cage production to meet the requirements of special bearings. This kind of products are widely used in aerospace bearings and some acid-base cleaning industry and food industry and other fields.
