Conductive silicone rubber dispersion for the cable industry
Wacker Chemie
Powersil 403 silicone rubber dispersion (photo) is an electrically conductive dispersion developed for manufacturing the outer conductive film on cable accessories for transmission and distribution cables. The two-component formulation contains addition-curing silicone rubber, which adheres well to the insulating silicone substrate while forming a flexible film. Elongation at break is roughly 650% for this formulation, and its tear strength is 20 N/mm. This means that a conductive film made from Powersil 403 can withstand extreme elongation, without cracking. The low-viscosity liquid contains no toluene, and can be easily applied by spraying, dipping or brushing. Its electrical properties also make the dispersion suitable for use in antistatic coatings for textiles. Hall 6, Stand A10 — Wacker Chemie AG, Munich, Germany
