Machinability of PEEK Plastic
it’s important to note that these values can vary based on the grade of PEEK and its processing conditions. Here is a generalized example based on typical values found in standard grades of PEEK:
| PEEK Properties | Description | Typical Values |
|---|---|---|
| Tensile Strength, Yield (MPa) | Measures the maximum stress PEEK can handle before deforming, crucial for structural integrity. | 90-100 MPa |
| Heat Deflection Temperature (°C) | Temperature at which PEEK deforms under load, important for applications involving high heat. | 150-160 °C |
| Chemical Resistance | Ability to withstand aggressive chemicals, essential for harsh environments like chemical processing. | Excellent resistance to a wide range of chemicals |
| Tensile Modulus | Indicates the stiffness and mechanical strength, important for applications requiring rigidity. | 3,700-4,000 MPa |
| Impact Strength | Measures the material’s capability to withstand sudden and severe impacts, critical in dynamic environments. | 7-16 kJ/m^2 |
| Glass Transition Temperature (°C) | Temperature at which the material softens from a glassy to a rubbery state, affecting thermal stability. | 143 °C |
