Professional-grade self-fusing silicone rubber electrical tape rated for 356°F with exceptional arc and track resistance, ideal for high-voltage cable termination and industrial electrical applications.
Scotch® Self-Fusing Silicone Rubber Electrical Tape 70 is a professional-grade, high-temperature arc and track-resistant tape designed for demanding electrical applications. Composed of self-fusing, inorganic silicone rubber with an easy-tear and easy-strip liner, this tape is engineered to provide superior protection for terminating high voltage cables. The tape withstands extreme temperatures up to 356°F (180°C) and maintains its integrity in harsh environmental conditions, making it ideal for industrial, utility, and renewable energy applications.
This electrical tape features exceptional instantaneous fusion properties, allowing the silicone rubber layers to fuse together when wrapped, creating a seamless, continuous protective barrier without the need for adhesive. With a dielectric strength of 34 kV/mm and a voltage rating of 35 kV, it provides excellent electrical insulation and protection against electrical arcing and tracking. The tape's high elongation at break (450%) ensures flexibility during application and reliable performance under thermal stress and vibration.
The Scotch® 70 tape is RoHS 2011/65/EU compliant and meets rigorous industry specifications including ASTM D-495-71, AA-59163 Class-I Type I, and ASTM D-1000-76. Its chemical-resistant and UV-resistant properties make it suitable for outdoor and indoor applications across multiple industries including aerospace, automotive, marine, commercial and industrial construction, mining, solar, and wind power. Each case contains 24 rolls, with each roll measuring 1 inch wide by 30 feet long, providing ample coverage for extensive electrical maintenance and repair operations.
