3M 44HT Composite Film Electrical Tape

3M™ Composite Film Electrical Tape 44 is an industrial grade tape product with a web-reinforced polyester film mated with a pressure sensitive rubber thermosetting adhesive. 3M 44HT is a high tack version of 3M 44. This product is used for application with stick-wound coils, transformers and bobbin-wound coils. It is suitable for functions necessitating banding, anchoring, insulating and protecting. Designed and constructed for demanding electrical needs, this product provides puncture resistance and excellent electrical properties even at high temperatures.

The combination of the thermosetting, rubber adhesive and the polyester-web and polyester film backing provides excellent adherence and dielectric strength
Offers great electrical properties and is puncture-resistant
Very high tack adhesive for quick, reliable holding on motor windings, oily magnet wire and uneven surfaces

Color: Tan

Backing/Carrier Material: Polyester Film/Nonwoven Composite

Adhesive Type: Thermosetting Rubber

TotalThickness: 5.5 mil
