OEM 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.

Heat Shrink OEM Liquid Resins EMC & RFI Products About 3M 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. 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. 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. 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. 30 To find out more about our complete range of Electrical Products, please call our Customer Service Team on 01234 229 462
