Material Notes:
Polyamide shows both a high thermostability and high stiffness, hardness and toughness. These are some of the main characteristics. Due to the fact, that the good mechanical characteristics will be achieved only after conditioning, this material must be conditioned again after annealing. In addition, this conditioning occurs with a longer storage in air automatically. This polyamide has the highest hardness, rigidity, and a good resistance to wear and heat deflection temperature.Properties:high impact strength and stiffnesshigh impact and notching impact strengthhigh heat deflection temperaturegood at dampeninggood glide and limp home charactersgood chemical stability against organic solvents and fuelssize alteration by humidity absorption must be considereddimension stability, electrical and mechanical properties may become affected by absorbing moisture or waterApplications include bearing parts, gear wheels, pump parts, sliding rails, castors, and fittings.
