3M Electrical Tapes

3M™ 56 – High-Performance Polyester Tape for Demanding Electrical Applications

3M™ 56 is a high-performance, yellow polyester electrical tape featuring a thermosetting rubber-based pressure-sensitive adhesive. Designed for insulation applications requiring high dielectric strength (up to 600 V), it withstands temperatures up to 130°C, and offers excellent resistance to moisture, chemicals, abrasion, and cuts.

This tape complies with UL standards and the RoHS 2011/65/EU directive, making it ideal for industrial electrical use. Its polyester film backing (0.064 mm thick) ensures dimensional stability and durability in continuous operation.
