Polyester Film/Mat Composite with Rubber
Thermosetting Pressure-Sensitive Adhesive
Data Sheet Product Description Applications 3M™ 55 Tape is a Polyester Film/Mat Composite with 3M 55 Tape has excellent physical and electrical rubber thermosetting pressure-sensitive adhesive. characteristics. This tape is especially well suited for use as a coil cover. For end turns, lead pad and core layer and High edge-tear resistance crossover insulation. High puncture and abrasion resistance Class B (130°C) For maximum solvent resistance and holding properties the tape should be thermoset at one of the following cycles: 1 hour @ 150°C (300°F) 2 hours @ 135°C (275°F) 3 hours @ 120°C (250°F) Properties | Typical Values | *Thickness | 7.5 mils (.190 mm) | *Tensile Strength | 35 lbs.
