The
Torlon PAI grades (polyamide-imide), combine 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 for high temperature applications. Torlon PAI also has resistance to chemicals, including strong acids and organic materials, making it an ideal product for highly concentrated working environments.

Torlon
4203 Polyamide-imide (PAI) yellow-ochre
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 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 such as connectors, switches, relays, ball
bearings and rollers.
Torlon
4301 Polyamide-imide (PAI + graphite + PTFE) 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.
Torlon
4501 Polyamide-imide (PAI + graphite + PTFE) black
This
compression moulded material is similar in composition
to TORLON 4301 PAI, and is selected when larger shapes
are required.
Torlon
4503 Polyamide-imide (PAI) yellow-ochre
This
compression moulded material is similar in composition
to TORLON 4203 PAI, and is selected when larger shapes
are required.
Torlon
5530 Polyamide-imide (PAI-GF30) khaki grey
This
30% glass fibre reinforced grade offers higher stiffness,
mechanical 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. The suitability of this material
for sliding parts, however, is to be carefully examined
since the glass fibres tend to abrade the mating surface.
Torlon Proven Applications
Chip nests and sockets
 By retaining dimensional stability over a broad temperature range, parts made of Torlon 5530 improve reliability of test connections and extend part life. (Prior materials : Vespel*PII)
Bearing cages
 Torlon 4203 and 4301 PAI's low expansion rate and excellent wear resistance enable manufacturers to increase bearing speeds and extend part life. (Prior materials: Steel Cages, Hardened Steel Balls, Bronze Bushings)
Can mandrel
 4203 PAI's extraordinary compressive strength and abrasion resistance permit higher production rates and increased support of aluminium cans during printing. (Prior materials: Nylon, UHMW, Ceramic-coated Steel)
Torlon Technical Notes
As Torlon PAI has a relatively high moisture absorption rate, parts used in high temperature service or made to tight tolerances should be kept dry prior to installation. Thermal shock resulting in deformation can occur if moisture laden parts are rapidly exposed to temperatures above 200°C.
