Description

ISO-PEEK is a semi-crystalline, high-performance thermoplastic, which has, next to very good mechanical properties, a high sliding performance. In addition, the material has a high temperature resistance. ISO-PEEK is often used for sliding guides and seals. The key features are:


  • High chemical resistance
  • Excellent sliding functionality
  • Very high temperature resistance
  • Related Standards
