Advanced Thermoplastics

Rubberatkins offers a specialised range of high-performance thermoplastics designed to complement our advanced sealing solutions. Engineered to enhance the anti-extrusion performance of elastomeric seals, our thermoplastic grades deliver exceptional reliability in extreme high-pressure and high-temperature environments.

We currently supply four primary in-house thermoplastic grades PEEK, PEKK, PEKEKK, and Hytrel® available in both unreinforced and reinforced formulations. These materials are engineered for longevity, thermal stability, and durability in demanding operational conditions. Components can be custom moulded or precision machined to provide robust, application-specific solutions.
