Res-I-Band banding film is a heat shrinkable polyester film specially designed for use with glass banding tapes to improve the finish and appearance on banded armatures and commutators. The pre-set and uniform shrinkage of Res-I-Band improves resin flow and provides a smooth finish on the glass band. It also minimizes build up of foreign matter thereby reducing the possibility of tracking. It enhances the performance, insulation integrity and the appearance of the glass bands on armatures and commutators. Res-I-Band provides an accurate and consistent 5% shrink factor yielding the ultimate in smooth surface banding. - Res-I-Band is treated with a special release backing to insure easy and complete removal from the band. The special release backing contains no silicones which can contaminate the glass band. Unlike conventional banding films, Res-I-Band will not become homogenous with the band and will not result in flaking when removed. The special release backing permits you to use a 1 mil. thick Res-I-Band film as opposed to a 2 Mil or 3 Mil conventional banding film, thereby, reducing material costs up to 50%. Res-I-Band is easily initiated and terminated by using a pressure sensitive tape.
