· high strength and stiffness

· high impact and notching impact strength

· high heat deflection temperature

· good glide and emergency operation features

· good chemical stability against organic solvents and fuels

· size alteration by humidity absorption must be considered

· dimension stability, electrical and mechanical properties

  may become affected by humidity absorption

· Bearinf partsl(good sliding properties)

· Gear wheels, pump parts, sliding rails

· Castors(reduction of the noise level), fittings
