Polytetrafluoroethylene – the industry standard for chemical inertness and ultra-low friction. Ideal for static sealing, anti-stick surfaces, and cryogenic to high-temperature applications. Our PTFE O-rings and PTFE gaskets are available in virgin and filled grades.
Polyetheretherketone – a high-strength semi-crystalline thermoplastic with outstanding mechanical and thermal properties. Preferred for dynamic sealing and heavy-duty wear applications. Our PEEK seals offer superior creep resistance and are ideal for high-pressure hydraulic systems, oil & gas downhole tools, and aerospace components.
