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 |
