Short definition
Polyetheretherketone fibres (PEEK) are high-performance thermoplastic fibres characterised by high temperature resistance, good chemical and radiation resistance and high rigidity. Their combination of thermal stability and resistance to harsh industrial conditions makes them suitable for highly specialised technical sewing applications.
Properties
- High temperature resistance
- Good radiation and chemical resistance
- High rigidity
Temperatures
- Continuous temperature resistance up to approx. 250°C
- Melting point: approx. 330°C
