PEEK Material

PEEK (polyetheretherketone) is a high-performance engineering plastic with excellent properties such as high temperature resistance, chemical corrosion resistance and mechanical strength. It is a high molecular polymer synthesized from raw materials such as terephthalic acid and hydroquinone. PEEK plastic has excellent high temperature resistance and can maintain stability under continuous use temperatures of up to 250°C, and can even reach over 300°C in a short period of time. At the same time, PEEK also shows good chemical resistance and can resist the erosion of most chemicals, including acids, alkalis, solvents, etc. In addition, PEEK has excellent mechanical properties, including high strength, rigidity and wear resistance, allowing it to maintain stability under high load and high friction conditions. Due to its excellent performance, PEEK is widely used in aerospace, automotive, medical equipment, electronic and electrical, chemical and other fields, such as manufacturing high-temperature parts, chemical processing equipment, medical equipment parts, etc. PEEK plastic is an important engineering plastic that provides key support for the development of various industries.
