VESTAMID® L X7297
聚酰胺12
Plasticized VESTAMID® polyamide 12 compounds
Characterization: high viscosity, plasticized, light and heat stabilized
Applications: flexible tubing and hoses
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.
