Duratron® PAI Family of Products
Duratron® PAI is a family of the highest performing, melt processable plastics, characterized by superior resistance to elevated temperatures. These plastic grades are capable of performing under severe stress conditions at continuous temperatures to 260 °C (500 °F). Parts machined from Duratron® PAI stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics. An amorphous material with a Tg (glass transition temperature) of 537°F (280°C), Duratron® PAI's extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range. A post-curing cycle is sometimes recommended for components fabricated from extruded shapes where optimization of chemical resistance and/or wear performance is required. For large shapes or custom geometries like tubular bar, compression molded Duratron® PAI shapes offer designers the greatest economy and flexibility.
Common applications of Duratron® PAI products include electrical connectors, bearing cages, mandrels, chip nests and sockets, and labyrinth seals.

friction applications. This grade is similar in composition to
Duratron® T4301, offering a very high flexural modulus and exhibiting
little-to-no stickslip, and is able to endure harsh thermal, chemical,
and stress conditions. Duratron® T4501 PAI is a reliable solution for
parts requiring larger geometries and high compressive strength.
Duratron® T4301 PAI
Duratron® T4301 PAI is a graphite-filled polyamide-imide offers a very
low expansion rate and coefficient of friction, exhibiting little to no
stick-slip. The addition of PTFE and graphite provides higher wear
resistance compared to the unfilled Duratron® T4203 PAI grade, and also
gives Duratron® T4301 PAI excellent dimensional stability capabilities
over a wide temperature range. Duratron® T4301 PAI’s flexural modulus of
1,000,000 psi is higher than most other advanced engineering plastics,
which allows it to excel in severe service wear applications such as
non-lubricated bearings, seals, bearing cages, and reciprocating
compressor parts.

Compression-molded Duratron® T4540 PAI Polyamide-imide shapes were
developed specifically for advanced fluid management industries for use
in rotating equipment applications. As a sealing and bearing grade PAI
that offers a very low coefficient of friction and superior wear
properties, typical applications for Duratron® T4540 include labyrinth
seals, wear rings, bushings, and bearings.
Duratron® T5530 PAI
Duratron® T5530 is a compression-molded, 30% glass reinforced PAI that
offers high stiffness, strength, and creep resistance. Although similar
in composition to Duratron® T5030, Duratron® T5530 comes in larger
geometries, making it ideal for structural applications meant to support
high static loads for extended periods of time, especially at high
temperatures. Additionally, Duratron® T5530 exhibits superior
dimensional stability up to 482° F / 250° C, making it a favored

industry.
Duratron® T4301 PAI AE
Duratron® T4301 PAI AE (aerospace) offers a very low expansion rate and
coefficient of friction, and also exhibits little to no slip-stick in
use. The addition of PTFE and graphite provides higher wear resistance
compared to the unfilled Duratron® T4203 PAI grade, and also gives
Duratron® T4301 PAI AE excellent dimensional stability capabilities over
a wide temperature range. Duratron® T4301 PAI AE's flexural modulus of
elasticity is higher than most other advanced engineering plastics,
which allows it to excel in severe service wear applications in
aerospace engineering such as non-lubricated bearings, seals, bearing
cages, and reciprocating compressor parts.

Duratron® T7130 PAI Polyamide-imide is a 30% carbon fiber-reinforced
grade that offers exceptional stiffness, nonabrasive wear performance,
and the lowest coefficient of thermal expansion of all PAI materials.
These characteristics give Duratron® T7130 PAI the ability to withstand
high pressure environments in off-shore equipment applications, making
this grade a reliable choice for long term performance requirements. It
can be easily machined to the close tolerance that precision parts
require.
Duratron® T5030 PAI
Duratron® T5030 PAI Polyamide-imide offers high rigidity, retention of

for structural applications within the semiconductor and electronics,
and aerospace industries. It is well suited for structural applications
supporting static loads for long periods of time at high temperatures.
In addition, Duratron T5530 PAI exhibits superb dimensional stability up
to 260°C making it extremely popular for precision parts in the
electronical and semiconductor industries. The suitability of Duratron
T5530 PAI for sliding parts, however, is to be carefully examined since
the glass fibers tend to abrade the mating surface.
Duratron® T4203 PAI
Duratron® T4203 PAI Polyamide-imide offers the most superior impact
strength of all Duratron® T PAI grades, while also possessing the
