Abstract:
A material consisting of gas and polymer in a closed cell structure is called a foam. An insulation material that is foamed will have a lower dielectric constant and dissipation factor than the solid material. A polymer with a low dielectric constant, when foamed, will yield cable designs that are smaller and lighter than electrically equivalent designs using solid insulation materials. This paper describes the basic properties of such a polymer. Data is presented on the mechanical properties of wires insulated with this foamed material. Theoretical electrical properties and calculated polymer weights for MIL-STD-1553B data bus constructions are also presented.
