Description
Medical Grade PEEK features a combination of very high rigidity, hardness, tensile strength, and bending strength (high toughness and fatigue strength), high heat deflection temperature, and excellent resistance to disinfectants and detergents. It also has an exceptionally high hydrolytic stability so that repeated sterilisation in steam is possible without any problems.
Characteristics of Medical Grade PEEK include:
- Excellent sterilisability with all standard methods (superheated steam, gamma, E-beam, EtO)
- Very high stability, rigidity, and toughness
- Very high thermal stability and heat deflection temperature
- Very high creep resistance
- Very high dimensional stability
- Very high radiation resistance
- Very high hydrolysis resistance
- Good wear properties
- Low water absorption
- Inert
