| Unfilled VESTAMID® polyamide 12 compounds Characterization: high viscosity, highly heat stabilized Applications: hot diesel fuel lines 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.&& |
