DuPont Teijin Films Mylar® EL21 Polyester Film, 1400 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Mylar® EL21 polyester films are flexible strong and durable films with an unusual balance of properties, making them suitable for a variety of industrial applications. The excellent dielectric strength, moisture resistance, and physical toughness make Mylar® EL21 a very versatile and functional insulating material.

General Product Info: Mylar® EL21 films offer high dielectric strength, good chemical resistance, and exceptional durability in high-temperature environments

Typical Applications: Mylar® type EL21 films, similar to Mylar® type MO films, are heavy gauge insulating films designed for general purpose electrical/electronic applications, such as transformers, laminates, bus bars, and punched parts.

Approvals: UL 94 VTM-2 - for 92-1400 gauge(0.023-0.35 mm) and UL Recognition - for 92-500 gauge (0.023-0.13mm) HWI=5, HAI=4, CTI=1;for 700-1400 gauge (0.18-0.35mm) HWI=4, HAI=0, CTI=1
