DuPont Teijin Films Mylar® EL Polyester Film, 92 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Mylar® EL films, typically 48 through 500 gauge are strong, tough, general -purpose films for electrical/electronic uses. Heavier gauges of Mylar® EL films are similar to Mylar® MO films. Available in grades from clear to hazy, Mylar® EL films offer chemical inertness, good dielectrics, high temperature durability, and good handling characteristics.

General Product Info: The superior electrical, mechanical, thermal, and chemical inertness characteristics of Mylar® type EL films make them ideally suited for electrical and electronic applications.

Typical Applications: The outstanding strength, flexibility, and electrical properties of Mylar® type EL films make them well suited for many electrical and electronics applications. The good handling and winding characteristics make them especially suitable for coating, die cutting, embossing, and laminating operations.

Approvals: UL 94 VTM-2 - for 92 - 500 gauge (0.023 - 0.13mm)
