Abstract. Influence of glass microballs on heat conductivity of polymeric materials is investigated. Influence of glass microballs concentration and temperatures of heating on heat conductivity of a composite material is shown. The reasons of change of heat conductivity of a composition are explained, because heat conductivity of glass microballs differs on the order in comparison with heat conductivity of a polymeric matrix.
Keywords: polymeric composition, polyurethane, heat conductivity, glass microballs.
