MYLAR® C

Product Description

Mylar® Type C films are available in a wide range of generally thinner gauges (typically 6 through 92) that offer
excellent electrical properties, combined with superior strength and dimensional stability.

General Product Info

Mylar® Type C films offer the ideal combination of tensile strength, dimensional stability, and electrical properties
needed for use in capacitors.

Typical Applications

Mylar® Type C films were developed specifically as a dielectric for use in metallized and film/foil capacitors. Typical
capacitor applications include energy storage, frequency discrimination, filtering, coupling, and by-passing.
