For now, Teighax 309 represents the culmination of three years of R&D focused on recyclability without property loss . Early recycling tests show that reground Teighax 309 retains 88% of virgin tensile strength after one remelt—a major step forward for circular manufacturing. If your current project involves any combination of heat above 120°C, cyclic loading, and exposure to hydrocarbons or coolants , then yes—what’s new in Teighax 309 solves problems that previously required switching to expensive PEEK or PEKK.

It is an advanced, semicrystalline engineering thermoplastic that is new because it combines high-temperature resistance (165°C), improved UV stability, moisture barrier properties, and superior powder reusability for 3D printing—features previously unavailable in any Teighax-grade material.
