3M Electrical Tapes are fabricated with a broad range of backings and adhesives for the optimal balance of electrical and mechanical properties while maintaining good handling characteristics. 3M Flexible Insulations have been designed to different levels of thermal, electrical, and mechanical performance to meet the appropriate transformer requirements with the most cost-effective solutions that meet the stringent quality requirements.

3M 74 Tape is a 0.5-mil polyester film with rubber thermosetting adhesive, 0.5-mil polyester film backing rubber thermosetting adhesive.

APPLICATIONS:

• 3M 74 Tape is conformable; provides good electrical strength for coil applications where space is at a premium.
• Transformer wrapping
