Torlon® PAI Index
With its versatile performance capabilities and proven use in a broad range of applications, Torlon PAI polyamide-imide PAI shapes are offered in extruded, injection molded, and compression molded grades.Torlon is the highest performing, melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from Torlon stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics
Main properties of our range of Torlon sheet, rod and tube are:
- Very high maximum allowable service temperature in air (250°C continuously)
- Excellent retention of mechanical strength and stiffness over a wide temperature range
- Extremely low coefficient of linear thermal expansion up to 250°C
- Excellent wear & frictional behaviour (particulary TORLON 4301 PAI)
- Outstanding UV-resistance
- Inherent low flammability
- Exceptional resistance against high energy radiation (gamma and X-rays)
The following grades of Torlon are available to buy online - please select from:
- Torlon 4203 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, Torlon 4203 PAI 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.
Available colours: Yellow-Ochre Available to buy in: sheet and rod - Torlon 4503 PAI
Torlon 4503 compression moulded material is similar in composition to Torlon 4203 PAI, and is selected when larger shapes are required.
Available colours: Yellow-Ochre Available to buy in: sheet and rod - Torlon 4301 PAI
The addition of PTFE and graphite provides higher wear resistance and lower coefficient of friction compared to the unfilled grade. Torlon 4301 PAI also offers excellent dimensional stability over a wide temperature range. This grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts.
Available colours: Black Available to buy in: sheet and rod - Torlon 4501 PAI
This compression moulded material is similar in composition to Torlon 4301 PAI, and is selected when larger shapes are required.
Available colours: Black Available to buy in: sheet and rod - Torlon 5530 PAI
This 30% glass fibre reinforced grade offers higher stiffness, strength and creep resistance than Torlon 4203 PAI. It is well suited for structural applications supporting static loads for long periods of time at high temperatures. In addition, Torlon 5530 PAI exhibits superb dimensional stability up to 250°C making it extremely popular for precision parts for example in the electrical and semiconductor industries. 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.
