PAI

PolyAmidimide

SCROLL

This high-performance plastic demonstrates an excellent combination of mechanical use behaviour and dimensional stability in applications at high temperatures.


This material can even be used at high tension at service temperatures of up to 250°C. PAI semi-finishes products have a higher pressure and impact resistance than most other technical plastics. A very low thermal expansion coefficient, high load capacity, and wear resistance ensure long-lasting and reliable products. PAI is an amorphous material and should be stored in a dry place. If high chemical and hydrolysis resistance are required, another material should be chosen. PAI is also known as TORLON® and is available in the following manifestations.

This material has added graphite and PTFE resulting in a higher wear resistance and lower sliding friction coefficient than TORLON 4203 + 4503. It demonstrates excellent dimensional stability across a wide range of temperatures. It is especially suitable for use in dry-running sliding elements, gaskets, bearing cages, and more.

Looking for a material with a combination of electrostatic discharge (ESD), high strength, and thermal stability? Then this is the one for you! Semitron® ESd 520HR! This new ESD material is ideal for producing carriers, bushings, and contactors for test equipment and other components used for handling structural elements. Semitron® ESd 520HR‘s most important quality is its unique resistance to dialectical breakdowns at high voltages (>100 V). With normal carbon fibre reinforced materials, conductivity increases irreversibly if subjected to even slight tension. Only Semitron® ESd 520HR maintains its original electrical properties under all tensions while also offering the required mechanical strength for demanding applications.
