Special engineering plastics are a type of engineering plastic materials with high comprehensive performance and long-term use temperature above 150°C, such as polyphenylene sulfide (PPS), polyimide (PI), polyether ether ketone (PEEK), liquid crystal polymer (LCP) and polysulfone (PSF). These plastics have a rigid skeleton, a high melting point and an orderly arrangement of molecular chains, showing excellent stability in high-temperature environments. Special engineering plastics are mainly used in electronic, electrical and special industrial fields to meet special performance requirements such as high temperature, corrosion resistance and wear resistance. They are used to manufacture electronic components, insulation materials, chemical equipment and automobile engine parts.
China's special engineering plastics industry as a whole has shown a steady growth trend. In recent years, the market size of this industry has continued to expand. By the end of 2022, China's special engineering plastics market size has exceeded 17.5 billion yuan. This is due to the industry's high performance and wide application, meeting the needs of electronic and electrical, aerospace, automotive and other fields. Government support and technological innovation further promote industry development. The demand for specialty engineering plastics is growing rapidly in emerging markets and regions and is expected to continue to be a major driving force in the coming years. Challenges facing the industry include fierce competition and environmental regulations, but the overall development prospects remain positive, providing opportunities and potential.
