Intertape® – Electrical adhesive tapes Intertape® 4237
Intertape® 4237 is a glass filament polyester tape with acrylate adhesive.
High tensile strength glass filaments and conformable PET film coating with an aggressive adhesive for a variety of heavy duty insulating, banding and holding applications. 1.0 mil polyester film provides puncture, edge tear and abrasion resistance. Specially designed and intended for use in oil-filled transformers. Once thermoset, the acrylic adhesive offers superior resistance to chemicals, solvents and aging in addition to excellent dielectric strength and insulation resistance.
Lead and saddle tie down, banding and bundling motor and transformer coils and coil covering.
Exceeds as one of a very few products available the rigorous requirements of the ASTM D3455 „Test Method for Compatibility of Construction Material with Electrical Insulating Oil of Petroleum Origin“.
