MYLAR® EC

Product Description

Mylar® EC films are electrical grade films designed for use in applications where improved dimensional stability is required. In addition to lower levels of shrinkage, Mylar® EC films offer outstanding durability, chemical inertness, good dielectrics, and good handling characteristics.

General Product Info

The outstanding strength, flexibility, and electrical properties of Mylar® EC films, combined with lower than normal shrinkage levels, make them especially suited for circuitry and membrane touch switch applications. The film's moisture and chemical resistance serve as a barrier to substances that could contaminate membrane touch switches.

Special Features

Slit rolls are available in the following ID and OD configuration: 3" ID 9 1/2" OD 3" ID 13" OD 3" ID 18" OD 6" ID 11" OD 6" ID 14" OD 6" ID 18" OD Master rolls are available as shown in the Standard Put-Ups 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.

Typical Applications

The unique balance of properties offered by Mylar® EC films makes them ideal for membrane switches and flexible circuits used in a variety of consumer and industrial products, including automotive instrument clusters, computers, calculators, telephones, cameras, and appliances.
