Why use Torlon?...
Torlon polyamide-imide is recognized as the highest performance thermoplastic that is still melt processible. Torlon can be extruded into shapes and injection molded into custom geometries.
With a 270°C and more heat distortion temperature (softening temperature) and a 200 - 220 °C continuous service
temperature(UL RTI), Torlon offers unmatched strength at elevated temperatures. It is better at 200°C than any other engineering resin at room temperature. Torlon is also tougher and more impact resistant at
cryogenic temperatures than other high strength polymers.
... and why PEEK?
PEEK is recognized as having the best balance of chemical resistance, wear resistance and heat resistance among all thermoplastics. It is melt processible allowing for processing into shapes by extrusion and parts by injection molding.
Technically PEEK is part of a family of polyarylether ketones (PAEK) but the PEEK acronym is most recognized. Related chemistries based on PEK and PEKK offer unique thermal benefits to the traditional PAEK’s.
