^{3M Electrical Tape 46 Polyester Film/Glass Filaments ----  No Longer in Production}

^{3M 聚酯薄膜纖維強化膠帶 46 熱固橡膠粘劑 ---- 沒生產了 please check Tape 1146}

3M Filament Reinforced Electrical Tape 46 is a 7 mil glass filament-reinforced polyester film backing  with a thermosetting, pressure-sensitive rubber adhesive system. It offers good tensile strength and edge-tear resistance for use in end-turn taping.

High tensile strength / High dielectric strength / UL recognized Class B (130°C)

The polyester film/glass backing has excellent physical and electrical characteristics. 46 tape is especially suited for such applications as lead anchoring and banding of coils where high edge-tear resistance and low stretch under application tension are needed.
