3M™ Electrical Tape 44
Specifications
3M™ Electrical Tape 44 is a low-halogen, polyester web-reinforced film with
thermosetting rubber, pressure-sensitive adhesive.
The tape shall be coated on one side with pressure-sensitive adhesive, which shall not
require heat, moisture or other preparation prior to or subsequent to application. The
adhesive coating shall be smooth and uniform and be free of lumps and bare spots.
There shall be no separator between adjacent layers of the roll. The tape shall
perform at a temperature of 262°F (130°C) without loss of physical or electrical
properties
For maximum solvent resistance and holding properties, the tape should be thermoset
at one of the following cycles:
1 hour @ 300° F (150° C)
2 hours @ 275° F (135° C)
3 hours @ 250° F (120° C)
