Duratron PAI (Torlon) | Plastic Stockist

Plastic Stockist provides a great selection of Duratron PAI plastic. The Duratron PAI (previously known as Torlon) grades combine excellent retention of mechanical strength, stiffness and creep resistance over a wide temperature range with extremely low thermal expansion for high temperature applications.

Duratron 4203 Polyamide-imide (PAI) is available in yellow-ochre and offers the best toughnes and impact strength of all Duratron PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, this extruded grade is very popular for precision parts in high-tech equipment. In addition, it's good electrical insulating ability provides numerous possibilities in the field of electrical components such as connectors, switches, relays, ball bearing and rollers.

Duratron 4301 Polyamide-imide (PAI + graphite + PTFE) is available in black. The addition of graphite and PTFE provides higher wear resistance and lower coefficient of friction compared to the unfilled grade as well as little or no stick-slip in use. This grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts.

Common uses for Duratron PAI Plastic

Duratron Sliding Compressor Vanes

Rotary compressors needed a vane material that could survive with limited lubrication and maintain close tolerances at high speeds and loads. Duratron 4301 was the ideal replacement for the composite material that was previously used.

Duratron Can Mandrel

Packaging equipment designers needed a material that had extreme strength and could deal with the impact occuring in real world production. Can mandrels are used to form aluminium blanks into beverage and food containers. Stiff, strong Duratron 4203 PAI permitted higher production rates because of its ability to operate at higher temperatures.
