ANALYSIS OF THE RELATIVE EFFECTS OF LOADING AGENTS AND THEIR INTERACTIONS AS A FUNCTION OF CORE RESISTIVITY IN THERMOSET POLYURETHANE FOAM PARTS

摘要

While there has been an increase in the use of certain polymers for electrically conductive applications, thermoset polyurethane foams have been primarily used in applications that do not require any electrical conductivity. The electrically insulative properties of these materials can be accentuated by the presence of air pockets inside of the foam parts. This investigation analyzes the effect loading agents have on electrical conductivity on thermoset polyurethane foam containing a conductive core. This paper discusses the relative effects of two loading agents - carbon black and graphite - on resistivity of a thermoset urethane part containing a conductive core as determined by statistical analysis through designed experiments.
