Description
Material Notes:
The addition of PTFE and graphite provides higher wear resistance and lower coefficient of friction compared to the unfilled grade as well as a lower tendency to stick-slip. Duratron T4301 PAI also offers excellent dimensional stability over a wide temperature range. This extruded Duratron PAI grade excels in severe wear applications such as non-lubricated bearings, seals, bearing cages and reciprocating compressor parts Very high maximum allowable service temperature in air (250°C continuously) Excellent retention of mechanical strength, stiffness and creep resistance over a wide temperature range Dimensional stability up to 260°C Excellent wear & frictional behaviour (particulary Duratron T4301 & T4501 PAI) Very good UV-resistanceGood resistance against high energy radiation (gamma- and X-rays) Inherent low flammability
