| Description | Mylar® type MO21 films are strong, heavy gauge films that have excellent electrical properties. These films offer exceptional cut through resistance, low shrinkage, low moisture absorption, and high thermal durability. Mylar® type MO21 films are used as insulation in systems that have been given Class B ratings by Underwriters Laboratories (UL). They also offer product uniformity that enhances processing on automatic slot and wedge insertion equipment. | |||||||||
