Intertape® – Electrical adhesive tapes Intertape® 4238
Intertape® 4238 has a laminate of polyester film and glass filaments as backing with acrylate adhesive.
Polyester film provides puncture resistance, abrasion resistance and resistance to edge tear. High tensile strength, conformable backing with aggressive adhesive for a variety of heavy duty insulating and holding applications. Very resistant to chemicals, solvents and aging, and offers excellent dielectric strength and insulation resistance.
Application
Lead and saddle tie down, banding and bundling motor and transformer coils and coil covering.
