3M Electrical Tapes

3M™ Polyester Film Electrical Tape 57

3M™ Polyester Film Electrical Tape 57 is a high-performance electrical tape featuring a durable polyester film backing and thermosetting rubber adhesive. It delivers excellent dielectric strength, mechanical robustness, and resistance to chemicals, moisture, and abrasion. This makes it ideal for insulating electrical components operating under elevated temperature or mechanical stress.

With a film thickness of 0.05 mm, dielectric strength of 7000 V, and operational temperature range up to +130°C, 3M™ 57 offers a reliable, long-term solution for electrical insulation and mechanical protection in a variety of demanding environments.

Applications

Layer insulation in transformers and inductors
Coil cover for motor windings
Wrapping for film capacitors
High-voltage electrical insulation
Moisture and solvent barrier protection
High-temperature electronic component shielding
