PEEK (PAEK) is formally known as polyether ether ketone (polyarylether ketone), a high-performance specialty engineering plastic with more advantages than other specialty plastics. Unlike polycarbonate, nylon, and others, PEEK (PAEK) has a main polymer chain primarily composed of benzene rings. This unique structure endows it with superior heat resistance, mechanical properties, chemical resistance, radiation resistance, stable insulation, and ease of processing. It is widely recognized as a high-performance thermoplastic material with excellent overall properties in harsh environments.

PEEK (PAEK) sheets have gained widespread application across various fields. With continuous technological advancements and a steady decline in prices, PEEK (PAEK) has evolved from being used in aerospace to replace metal materials for various aircraft components to now being utilized in high-tech industries such as petrochemicals, automotive, and specialized equipment. The breakthrough in domestic research on specialized plastics has allowed PEEK (PAEK) to not only meet domestic demand but also be exported overseas, breaking the foreign technological monopoly.
