PEEK (Polyether Ether Ketone) high-performance polymer is a high-temperature thermoplastic with a high glass transition temperature (162°C) and melting point (358°C), with a heat distortion temperature of up to 332°C (for 30% glass fiber or carbon fiber reinforced grades). It can be used continuously at 260°C and has an upper temperature limit that exceeds other high-temperature plastics such as PPS, PTFE, PAI, and PPU by nearly 60°C. PEEK resin not only exhibits superior heat resistance compared to other high-temperature plastics, but also possesses high strength, high modulus, high fracture toughness, and excellent dimensional stability. PEEK resin maintains high strength at elevated temperatures, with a bending strength of about 24 MPa at 200°C, and at 260°C, its bending strength and compressive strength are still 15~19 MPa. PEEK resin has high rigidity, good dimensional stability, and a low coefficient of thermal expansion, very close to that of aluminum materials. It also exhibits excellent chemical resistance, with corrosion resistance comparable to nickel steel, and possesses inherent flame retardancy, releasing less smoke and toxic gases under flame conditions, as well as strong radiation resistance. PEEK resin has good toughness and outstanding fatigue resistance to alternating stress, making it comparable to alloy materials. PEEK resin displays remarkable tribological properties, with excellent resistance to sliding wear and fretting wear, especially maintaining high wear resistance and low friction coefficient at 256°C. PEEK is easy to extrude and injection mold, with excellent processing performance and high molding efficiency. Additionally, PEEK has good self-lubrication, easy machining, stable insulation, and excellent hydrolysis resistance, providing comprehensive performance, good mechanical properties, high temperature resistance, and superior chemical resistance, making it a versatile plastic.
