3M™ Electrical/Electronic Tapes

3M

An electrical grade tape should always be used in the manufacture of electrical components. The correct tape will have the necessary balance of electrical and mechanical properties along with good handling characteristics that will contribute to overall productivity by reducing waste of time and materials. 3M™ Electrical Tapes are made from a broad range of backings and adhesives to meet the requirements of different applications and environments. Extensive quality control and testing, combined with accurate process controls, ensure that customers get high quality electrical grade products. 3M™ has developed a wide variety of tape families, each one with specific features for critical applications. 3M™’s tapes meet OEM quality standards and most are recognized by UL as noted in data sheets.


Tape Adhesives

Thermosetting Rubber (RT): Thermosetting adhesives have high initial adhesion and electrical purity. When properly thermoset, a rubber-resin adhesive system will cross-link into a three-dimension matrix molecular form providing greater adhesion and bonding, higher solvent resistance and higher heat resistance.

Acrylic (A): Acrylic adhesives are synthetic polymers specifically formulated to meet application requirements. Acrylic adhesives are compounded to resist heat, oxidation, solvents and oils, and exhibit acceptable performance in many applications without a cure cycle.

Silicone (ST): Silicone adhesives require considerably higher temperatures for the thermosetting reaction. Silicone adhesive systems have exceptional heat resistance, are inorganic and, if burned, leave a nonconductive residue.
