PEEK material with high-performance engineering plastic in excellent heat resistance, chemical resistance, mechanical strength and dimensional stability

It is a semi-crystalline, thermoplastic special engineering plastic developed by the British Imperial Chemical Industry Company (ICI) in 1978. Because PEEK has excellent comprehensive performance such as high temperature resistance, self-lubrication, corrosion resistance, flame retardant, hydrolysis resistance, wear resistance and fatigue resistance, it is used in the field of national defense and military industry, and gradually expanded to the civilian field, including industrial manufacturing, aerospace, automotive industry, electronic and electrical and medical equipment. With the continuous improvement of PEEK synthesis and processing technology, the high performance materials obtained by chemical modification, blending and composite filling have expanded its application field. PEEK is suitable for injection molding, extrusion molding, die molding and melt spinning and other processing methods, with the development of large aircraft, rail buses, automotive industry, medical and national defense industry, the demand for special engineering plastics represented by PEEK is also increasing, especially in improving the production and processing capacity of high-performance products.
