VESTAMID® L L1950
聚酰胺12
Unfilled VESTAMID® polyamide 12 compounds
Characterization: medium viscosity, heat stabilized, reduced friction and wear through molybdenum disulfide modification
Applications: guide rails, friction bearings
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.
