VESTAMID? L L-R9-MHI
聚酰胺12
Permanently antistatic and electrically conductive VESTAMID? polyamide 12 compounds
Characterization: medium viscosity, heat and light-stabilized, increased cold impact strength, with processing aid; especially designed for parts meeting EN 50014
Applications: antistatic and electrically conductive injection molded or extruded parts for use in areas prone to explosion such as coal mining and other industries, e.g., housings for explosion-protected measurement, fans for electric motors, housings for electric switches, chair castors, loudspeaker boxes, telephone and radio equipment, profiles for assembly lines, also with electric shock protection
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.
