Product Description
Scotch™ 130C Electrical Tape is a highly conformable
linerless Ethylene Propylene Rubber (EPR), high voltage
insulating tape formulated to provide excellent thermal
dissipation of splice heat. The tape is designed for use in
splicing and terminating wires and cables. Rated up to
90°C continuous operating temperatures and short term
130°C overload service. The tape will meet industry
specifications for flame retardance and has excellent
physical and electrical properties which provide
immediate moisture seals and void-free buildups. This
product can be used for low – and high – voltage (up to
69 kV) applications.
