Product Name:Polyetheretherketone
English Name:Polyetheretherketone
CAS No.:29658-26-2
Aliases:PEEK, Poly(oxy-1,4-phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene)
Molecular Formula:C19H16O3
Physical Properties:Polyetheretherketone is a semicrystalline aromatic thermoplastic polymer, appearing as off-white to light yellow granules or powder. It has a density of approximately 1.30 g/cm³, a melting point of about 343°C, and a glass transition temperature of approximately 143°C, with a long-term service temperature of up to 250°C. It exhibits excellent heat resistance, chemical resistance, flame retardancy, wear resistance, and electrical insulation. It maintains high mechanical strength at elevated temperatures and features a low coefficient of friction and good self-lubricating properties.
Uses:Polyetheretherketone is widely used in aerospace (such as satellite gas analyzer components and heat exchanger scraper blades), petrochemical, electronics and semiconductor (such as LCD manufacturing equipment parts), and mechanical sealing applications due to its excellent heat resistance, chemical resistance, and mechanical strength. Its superior tribological properties make it an ideal material for friction components such as sleeve bearings, sliding bearings, valve seats, sealing rings, and pump wear rings. It is also used in nuclear energy equipment parts, food processing line components, chemical machinery equipment parts, and electroplating equipment components.
Technical Specifications:
