POLYAMIDE-IMIDE (PAI)

TORLON® PAI

The TORLON PAI grades, combining excellent retention of mechanical strength, stiffness and creep resistance over a wide temperature range with extremely low thermal expansion up to 250°C, are top-rank materials to high temperature applications.

Main characteristics

• Very high max. allowable service temperature in air (250°C continuously)
• Excellent retention of mechanical strength, stiffness and creep resistance over a wide range of temperatures
• Extremely low coefficient of linear thermal expansion up to 250°C
• Excellent wear & frictional behaviour (particularly TORLON 4301 PAI)
• Excellent UV-resistance
• Inherent low flammability
• Exceptional resistance against high energy radiation (gamma and X-rays)

Applications

Rotary compressor vanes, can mandrels for printing, beaker welding supports, chip nests and sockets.

TORLON 4203 PAI (yellow-ochre) (PAI)

TORLON 4203 PAI offers the best toughness and impact strength of all TORLON PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, this extruded TORLON PAI grade is very popular for precision parts in high-tech equipment. In addition, its good electrical insulating ability provides numerous possibilities in the field of electrical components.

TORLON 4503 PAI (yellow-ochre) (PAI)

This compression moulded material is similar in composition to TORLON 4203 PAI, and is selected when larger shapes are required.

Delivery Programme: rod 50.80 - 368.30 mm, tube 42.86 - 882.65 mm

TORLON 4301 PAI (black) (PAI + graphite + PTFE)

The addition of PTFE and graphite 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 extruded grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts.

TORLON 5530 PAI (khaki grey) (PAI-GF30)

This compression moulded, 30 % glass fibre reinforced grade offers higher stiffness, mechanical strength and creep resistance than TORLON 4203 PAI and TORLON 4503 PAI. It is well suited for structural applications supporting static loads for long periods of time at high temperatures. The suitability of TORLON 5530 PAI for sliding parts, however, is to be carefully examined since the glass fibres tend to abrade the mating surface.
