CABELEC®  CA3839 - Cabot Corporation - 

CABELEC® 3839 is a static dissipative compound based on carbon black and a polypropylene copolymer. Its electrical and mechanical properties are permanent and are not dependent on atmospheric conditions. It has a good rigidity and can be easily processed on conventional molding equipment. The static dissipative nature of CABELEC 3839 provides products with a higher resistivity than usual conductive materials but ensures permanent static dissipation. It is therefore of interest in applications where slow discharge of static electricity is required. Moreover, CABELEC 3839 absorbs very little water from the atmosphere in normal usage conditions, which is a significant asset for applications where a very low moisture pick-up is mandatory for a good surface aspect. Suggested areas of applications are ordnance and ammunition works, mines, petroleum plants, electronics and other environments where freedom from the hazard of electrostatic discharge is an important condition.
