DEVELOPMENT OF FIBERMIX EXTRUDABLE INSULATION
Abstract
The contribution of the woven glass braid layer in wires such as Type II, MIL-W-5086A wire was found to be positive physical spacing from ground or from adjacent wire when the primary insulation was destroyed. A polyvinylchloride compound filled with 60% glass-flake is not able to provide the positive physical spacing accomplished by the glass braid layer. The glassflake, however, enables the polyvinylchloride to survive many of the severe tests to which the Type II wire was subjected without destruction of the primary insulation. The addition of glass flake to silicone rubber for extrusion on wire increases the short-term thermal life of the insulation. Teflon 100 (FEP) was not aided, in any of the tests performed, by the addition of glass-flake, but in Teflon 6 (TFE) high temperature shrinkage was greatly reduced. (Author)
