3M? Electrical Tape 44 is a low-halogen, combination polyester film/polyester web
film coated with a rubber thermosetting pressure-sensitive adhesive. This UL
recognized conformable tape is puncture resistant with excellent electrical properties.
Meets requirements of:
UL File No. E17385, Guide OANZ2
For temperatures not exceeding 130 °C
Used for stick-wound coils/transformers and in bobbin-wound coils for banding,
anchoring, and insulating, and for protecting start wires, leads, terminal strips,
insulation paper, end turns and connections in motors and transformers.
Not for specifications. Values are typical, not to be considered minimum or maximum.
