VESTAMID® L L-GB30
聚酰胺12
Reinforced, filled and flame-retardant VESTAMID® polyamide 12 compounds
Characterization: 30% microglass beads, medium viscosity, heat stabilized with processing aid
Applications: precision-molded parts with isotropic shrinkage, e.g., housings for gears, control valves and mechanical counters, pump impellers
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.
