State-of-the-art polyimide thermoset material used in aerospace for decades

• Excellent chemical compatibility with all aerospace fluids

• High temperature resistance (up to 365°C/690°F)

• Replaces elastomer products when they reach their temperature, pressure or chemical limits

• Installation in closed or blind grooves are possible with specific procedure and tools

• Almost unlimited design capabilities with no specific tooling required

• For rotary shaft applications, can handle high speed (up to 60 m/s)

• Easier to install and replace than mechanical seals, requires much less space and allows easier integration

• Testing capabilities for pre-validation

• Choice of more than 1,000 formulations that enhance desired properties:

– Mechanical strength – Wear resistance – Low abrasion in dynamic applications

• High wear resistance at various temperatures, as in track liner applications for thrust reverser systems

• Exceptional chemical resistance to harsh environments

• Different manufacturing processes available to produce:

– Bearings – Bushings – Cup seals – Piston rings – Custom components

• High temperature/mechanical strength combinations, as in stator vane bushing applications in engine compressors

• High dielectric strength properties such as engine electrical harnesses

• Excellent thermal stability for precise components such as bearings or piston rings in bleed air or de-icing systems

• High wear and self-lubricating properties for applications such as abradable seals or landing gear bushings for jet engines
