DuPont Teijin Films Mylar® MO21 Polyester Film, 1000 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Product 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.

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.

Typical Applications: 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.

Approvals: UL 94 VTM-2 - for 92-1400 gauge (0.023-0.35mm). UL Recognition - for 92-500 gauge (0.023-0.35 mm) HWI=5, HAI=4, CTI=1; for 700-1400 gauge (0.18-0.35mm) HWI=4, HAI=0, CTI=1
