3M™70 Scotch® silicone rubber electrical tape is a high temperature arc and track resistant tape composed of self-fusing, inorganic silicone rubber and easy-tear and easy-strip liner. It offers excellent track, arc and ozone resistance, high dielectric strength and excellent weathering characteristics.
Scotch® 70 tape is workable in extremely low temperatures and has excellent conformability and instantaneous fusion. This product is commonly used as an over-wrap for protection of terminating high-voltage cables against arcing and tracking and as primary insulation where Class “H” (180°) temperatures are encountered.
