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.
3M™ 1339 Tape - Glass Filament & Polyester Film with Acrylic Adhesive - (6.5 mils total thickness)
Especially suited to applications where transformer leakage is a problem. Polyester film used in making traditionally designed filament tapes does not absorb transformer oil. The uniqeue coating on the back side of 1276 tape promotes exceptional bonding of the diamond paper insulation epoxy during the transformer baking process.
Epoxy Film Tapes
Offering solder and puncture resistance, high dielectric strength, conformability and UL recognition for flame redundancy and use at temperatures up to 155° C. Their versatility can help reduce your tape inventory.
Glass Cloth Tapes
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.
PTFE tapes from 3M 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.
3M Polyimide Tapes are designed to be used in high temperature applications. The physical and electrical properties of polyimide remain stable when used in such applications as coils, harnesses and capacitors, that experience extreme temperatures.
