VESTAMID? L L-GF30
Polyamide 12
Reinforced, filled and flame-retardant VESTAMID? polyamide 12 compounds
Characterization: 30% chopped strands, medium viscosity, heat stabilized with processing aid
Applications: bearing cups for windshield wipers
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.
