What is PEEK – Polyether Ether Ketone

Polyether Ether Ketone (PEEK) is a high-performance engineering thermoplastic known for its exceptional mechanical strength, chemical resistance, and thermal stability. It can operate continuously at high temperatures up to 250°C and withstand harsh chemical environments. PEEK is widely used in aerospace, automotive, medical devices, and high-performance industrial components. It can be processed through injection molding or CNC machining, though both require precise temperature control and careful handling due to the material’s high melting point and hardness.

Property Typical Value / Description Notes
Tensile Strength 90–100 MPa Very high strength, suitable for load-bearing components
Flexural Strength 150–180 MPa Excellent rigidity for structural parts
Impact Strength (Notched) 50–70 J/m Moderate toughness; generally rigid and durable
Elastic Modulus 3.5–4.0 GPa High stiffness
Heat Deflection Temperature 250–260°C Can withstand continuous high-temperature operation
Density 1.30 g/cm³ Relatively heavy among engineering plastics
Chemical Resistance Excellent; resistant to acids, bases, and organic solvents Suitable for harsh chemical and high-temperature environments
Water Absorption <0.5% Very low, maintaining dimensional stability
Shrinkage 0.3–0.5% Low; mold design must still consider shrinkage for tight tolerance parts
Flammability UL94 V-0 High flame resistance

Common Applications of PEEK Molded Parts

Industry Example Parts Why PEEK Works Well
Aerospace Structural components, insulation High strength-to-weight ratio, heat resistance
Medical Surgical instruments, implant parts Biocompatibility, sterilization resistance
Automotive High-temp under-the-hood parts Chemical resistance, thermal stability
Industrial Pump components, seals, valve parts Wear resistance, dimensional stability
