Duratron™ T4301 PAI is a graphite-filled polyamide-imide offers a very low expansion rate and coefficient of friction, exhibiting little to no stick-slip. The addition of PTFE and graphite provides higher wear resistance compared to the unfilled Duratron™ T4203 PAI grade and also gives Duratron™ T4301 PAI excellent dimensional stability capabilities over a wide temperature range. Duratron™ T4301 PAI’s flexural modulus of 1,000,000 psi is higher than most other advanced engineering plastics, which allows it to excel in severe service wear applications such as non-lubricated bearings, seals, bearing cages and reciprocating compressor parts.
