Mylar type MO21 films are strong, heavy gauge films that have excellent electrical properties. These films offer exceptional cutthrough 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.
General Product Info
The inherit mechanical durability of Mylar® type MO21 films and their good dielectric and thermal durability characteristics endow these films with multiple advantages in motors and generators.
Slit rolls are available in the following ID and OD configuration:
- 3″ ID 13″ OD
- 3″ ID 16″ OD
- 3″ ID 18″ OD
Master rolls are available as shown in the Standard PutUps table. They are splice free and are available in selected widths in minimum order quantities of 35,000 lb per order with a minimum of 10,000 lb per item.
Mylar type MO21 films are being widely used for electrical insulation in slot liners, wedges and phase insulation for motors and generators. Mylar® type MO21 films are also frequently used in hermetic motor/compressor sealed units, fractional horse power motors, diaphragms, and industrial laminations.
