COMPOSITES FOR HIGH-FREQUENCY PRINTED CIRCUIT BOARDS AND METHODS OF MAKING

Abstract:

A composite includes at least one thermoplastic polymer; and at least one PTFE-based polymer, such that the composite has a dielectric loss tangent of less than 10.sup.-3. Moreover, a method for preparing a composite includes mixing at least one thermoplastic polymer with at least one PTFE-based polymer to form a homogenous mixture; melting the mixture to form a composite material; and hot pressing the composite material to form a composite sheet.
