PAI (polyamideimide)
Semi-finished products made of PAI have already proven their worth in a wide variety of applications thanks to their versatility and are available as extruded and press-sintered material grades.
In high-temperature applications, this high-performance plastic offers an excellent combination of mechanical service behavior and dimensional stability. The material can be used even under severe stress at continuous temperatures of up to 260°C.
Parts made from PAI semifinished products have higher compressive strength and impact resistance than most other engineering plastics. PAI’s extremely low coefficient of linear thermal expansion and high creep resistance provide excellent dimensional stability throughout its range of use. PAI is an amorphous material with a glass transition temperature of 280°C.
Properties
The properties of PAI are:- operating temperatures in continuous up to air 250°C or briefly 270°C
- retention of mechanical strength, stiffness and creep resistance over a wide temperature range
- excellent friction and wear behaviour (especially Duratron® PAI 4301 and 4501)
- excellent UV resistance
- very good resistance to high-energy radiation
- very low thermal expansion coefficient up to 260°C
- inherent flame retardancy
Duratron® T4203 PAI*
Properties:- excellent compressive strength and the highest elongation of all Duratron® PAI grades
- good electrical insulating properties and exceptionally good impact strength
- high dielectric strength
- high loads possible over a wide temperature range
- well suited for wear applications where impact loads and abrasion wear occur
- Wear applications: Bearings, sliding parts, sealing elements and thrust washers
- High temperature connectors
- Insulation parts
- Rods Ø 6,35 - 50,8 mm (Length: 1220 or 2440 mm)
- Plates 1220 x 305 x 4,75 – 25,4 mm
Duratron® T4301 PAI*
Properties:- the addition of graphite and PTFE results in higher wear resistance and a lower coefficient of sliding friction
- extremely low stick-slip susceptibility
- excellent dimensional stability over a wide temperature range
- dry-running sliding elements
- seals
- bearing cages
- Rods Ø 6,35 - 50,8 mm (Length: 2440 mm)
- Plates 1220 x 305 x 6,35 – 25,4 mm
Duratron® T5530 PAI*
Properties:- 30% glass fiber reinforced PAI
- higher stiffness and creep resistance than Duratron® T4203 PAI* and Duratron® T4501 PAI*
- excellent dimensional stability up to 260°C
- very well suited for parts that are exposed to large static loads in the higher temperature range over the long term
- glass fibers cause abrasion on the sliding partner
- chip plates and sockets
