Degussa AG Vestamid® L-R4-MHI Antistatic, Black, Electrically Conductive Nylon 12

Subcategory: Nylon; Nylon 12; Polymer; Thermoplastic

Key Words: PA12-HI,MHZ,16-010

Material Notes:
Description: Medium-viscosity, heat- and light-stabilized, increased low-temperature impact strength, with processing aid

Applications: Antistatic and electrically conductive moldings or extrudates for use in areas prone to explosions such as coal mining and other industries; e.g., housings for explosion-protected measuring equipment or for electric switches, ventilation fans for electric motors, chair castors, loudspeaker boxes, telephone and radio equipment, profiles for guide rails in assembly lines in the electronics industry. Also with electric shock protection.
