Electrical Tape 1339 is a polyester
film/glass filament tape coated with a
pressure-sensitive acrylic adhesive
system. The polyester film/glass backing
has excellent physical and electrical
characteristics. The back side of the tape
has a special coating which allows for an
even, controlled unwind. It also promotes
permanent anchoring in application.
Typical applications for 1339 include lead
anchoring, banding of coils, lead tape
anchoring and other uses where tensile
strength is needed.
