| Reinforced, filled and flame-retardant VESTAMID® polyamide 12 compounds Characterization: 15% chopped strands, medium viscosity, heat stabilized with processing aid Applications: gear box housing for electrical car window lifters In general, it can be said that long-chain, semi-crystalline polyamides absorb little water, are resistant to polar and non-polar solvents, exhibit low creep behavior and high impact resistance and can be used in a wide temperature range. Virtually no other polymer material in this price range exhibits these properties.&& |
