Arc-and track-resistant Silicone Rubber Self Fusing Tape

Arc-and track-resistant Silicone Rubber Self Fusing Tape


HarshMet SFT-40 Silicone Rubber Electrical Tape is a high temperature arc-and track-resistant silicone tape composed of self-fusing, inorganic silicone rubber and easy-tear and easy-strip liner. Typical applications are insulation , sealing and mechanical protection of wires, cables and other items that needs protection.


Excellent track resistance.
Excellent arc resistance.
Excellent ozone resistance.
High dielectric strength.
Class “H” material (180°C continuous operation).
Workable in extremely low temperatures.
Excellent conformability.
Excellent instantaneous fusion; does not need to be
held down.

Excellent weathering characteristics.

As an Over-wrap for protection of terminating
high-voltage cables against arcing and tracking.
High-voltage cables with these insulations should
be Over-wrapped:
Butyl rubber
Oil-base rubber
Ethylene propylene rubber
Low and high-density polyethylene cross-linked.
As primary insulation where Class “H”
(180°C/356°F) temperatures are encountered ie.

silicone rubber cables.
