Scotch Self-Fusing Silicone Rubber Electrical Tape 70 is a high-temperature arc and track-resistant tape composed of self-fusing, inorganic silicone rubber with easy-tear and easy-strip liner.

FEATURES:

• Excellent track resistance.
• Excellent arc resistance.
• Excellent ozone resistance.
• High dielectric strength
• Class H material (180ºC continuous operation).
• Workable at extremely low temperatures.
• Excellent instantaneous fusion; does not need to be held down.
• Matches Sky Blue Gray Munsell 5BG7.0/0.4.
• Excellent weathering characteristics.
• AA-59163 Class-I Type-I

APPLICATIONS:

• As an overwrap for protection of terminating high-voltage cables against arcing and tracking. High-voltage cables with these insulations should be overwrapped:

– Butyl rubber

– Oil-base rubber

– Ethylene propylene rubber

– P.V.C.

• Low and high-density polyethylene cross-linked
• As primary insulation where Class H (180ºC/356ºF) temperatures are encountered
• i.e., silicone rubber cables.
• As splice overwrap on spacer cable operating at 15kV and above
