PEEK (Polyether Ether Ketone)

Super Engineering Plastics
PEEK (Polyether Ether Ketone) is a semi-crystalline resin that combines excellent heat resistance, chemical resistance, and mechanical strength.
It features heat resistance comparable to thermosetting resins, along with the outstanding molding and processing capabilities characteristic of thermoplastic resins. As a high-performance material that enables "metal replacement" and "lightweight design," PEEK is widely used across various industries, including semiconductors, medical devices, automotive, electronics, and aerospace.
Features
  • Exhibits high rigidity and toughness, making it suitable for structural components and high-load applications.
  • Offers excellent heat resistance with a melting point of 343°C and a continuous use temperature of 260°C.
  • Achieves superior heat resistance and dimensional stability through glass fiber and carbon fiber reinforcement.
  • Demonstrates outstanding flame resistance equivalent to UL94 V-0 without the addition of flame retardants.
  • Shows excellent chemical resistance to a wide range of acids, alkalis, and organic solvents.
  • Features low friction coefficient and high wear resistance, making it ideal for sliding applications.
  • Supports semiconductor and medical applications due to its low outgassing and high-purity characteristics.
  • Maintains excellent dimensional stability even in high-temperature steam and hot water environments.
  • Provides stable electrical insulation properties in high-temperature and high-humidity conditions.
Applications
  • Automotive & Mobility: Drive components, sliding components, sealing components, EV-related components, brake-related components
  • Industrial Machinery: Pump and valve components, bearing components, conveyor system components, automation equipment-related components
  • Semiconductors & Electronics: Wafer carriers, semiconductor equipment components, electronic insulation components
  • Medical & Healthcare: Medical devices, implants, sterilization-compatible components
  • Robotics: Joint components, drive components, sensor-related components, actuator components
  • Drones & Aerospace: Aircraft structural components, motor-related components, lightweight components, aerospace wiring components
