Electrical Insulation Tapes
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 time and
materials. The simple appearance of a roll
of pressure-sensitive adhesive (PSA) tape
does not reveal the complex nature of the
material science, technology and advanced
production processes that are involved.
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.

About 3M OEM Electrical Insulation Tapes
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.
OEM Electrical Insulation Tapes
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.
Non-thermosetting Rubber (RN): An adhesive system is classified as non-thermosetting if it does not advance in cure upon application
of heat.
Adhesives for Special Applications: Developed exclusively by 3M, the remarkable adhesive used only for 3M™ Antistatic Tapes
uses a special polymer configuration to neutralise triboelectrically generated charges which could damage sensitive electronic
components upon unwind or removal.
Tape Backings
Acetate Cloth: These aesthetically pleasing tapes offer excellent conformability in coil wrapping applications up to 105° C plus excellent
absorption of electrical insulating resins and varnishes.
Composite Film: These combine the high dielectric strength and edge-tear
resistance of polyester film and non-woven polyester mat.
OEM Liquid Resins
Epoxy Film: These offer solder and puncture resistance, high dielectric strength,
conformability and UL recognition for flame retardancy and use at temperatures up
to 155° C. Their versatility can help reduce your tape inventory.
Filament-Reinforced: Many of these are designed for applications needing both
the dielectric strength of polyester film and the high mechanical strength of glass
fibres. They offer the ultimate in low stretch, high tensile and edge-tear resistance.
More cost effective than glass cloth tapes, they are excellent for anchoring lead wires
to banding coils. A special paper-backed filament tape is available for high-voltage
oil-filled distribution transformer use.
Glass Cloth: 3M offers the most flexible and conformable glass cloth backings on the market with the highest temperature resistance
and tensile strength. With excellent absorption of resins and varnishes, they are unsurpassed for holding and strapping applications up to
200°C.
Non-Woven: Permeable to gas and liquids, the design of this tape allows thorough penetration of varnishes during vacuum
impregnation.
Paper: These provide good cushioning, puncture resistance and toughness.
Polyester Film: These are specified for insulating applications requiring a thin, durable tape with high dielectric strength. They can
withstand higher temperature conditions than tapes with acetate backing. They also are conformable, exhibit excellent chemical, solvent
and moisture resistance and resist cut-through and abrasion.
Heat Shrink
Polymide Film: The physical and electrical properties of polymide remain stable when used in such applications as coils, harnesses and
capacitors, that experience extreme temperatures.
PTFE Film: These are high-temperature tapes used in applications requiring consistent performance and minimum shrinkage across a
wide range of temperatures. They are extremely resistant to chemicals, have high arc resistance and are free of carbonising materials.
