MYLAR WC

Product Description
Mylar WC films are general-purpose electrical grade films, similar to Mylar EL. These clear to hazy films are tough and durable as a core wrap. They offer good dielectrics and good handling characteristics.

General Product Info
Mylar Type WC films combine the tensile strength, dimensional stability, and dielectric strength needed for wire and cable applications.

Typical Applications
Mylar WC films possess the characteristics required for wire and cable used in the telecommunications and power transmission fields.

Approvals
UL Recognition - Product has been registered with Underwriters Laboratories.
