PEEK (PAEK) is a high-performance specialty engineering plastic, known for its numerous advantages over other specialty plastics, such as polycarbonate and nylon. Unlike them, the main chain of PEEK (PAEK) is primarily composed of benzene rings. This unique structure allows it to offer 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 suitable for harsh environments.

PEEK (PAEK) sheets are widely used across various applications. With continuous technological breakthroughs and a sustained decline in prices, PEEK (PAEK) has evolved from being used in aerospace to replace metal materials in various aircraft components to now being employed in high-tech industries such as petrochemicals, automotive, and special equipment. The breakthrough in the research of special plastics in China has not only met domestic demand but also allowed for exports abroad, breaking foreign technological monopolies.
