3M has a new polyimide film tape designed for high-temperature applications requiring a tough, thin backing that resists solvents.
3M polyimide film tape 1218 is UL recognized for use at temperatures up to 130 degrees C (formerly known as Class H). Unlike most such tapes, the new 3M polyimide film tape has an acrylic pressure-sensitive adhesive.
It can be used as insulation on coils, transformers, capacitors and wire harnesses, and also as a cover layer material for many types of flexible printed circuits.
3M polyimide film tape 1218 is available in standard and custom widths on a 3-inch polyester core. Standard length is 33 meters.
