Abstract
The present invention comprises a stain resistant flame retardant insulating composition that is stain resistant under conditions of natural aging, heat aging, or exposure to gases such as hydrogen sulfide or methane. The inventive insulating composition remains substantially white in color under elevated heating and combustion temperature conditions. The stain resistant electrical insulating composition of the present invention is also flame retardant and has a polymer system comprising ethylene-vinyl acetate copolymer and polyethylene. The composition also utilizes a vinyl silane component as a coupling agent, peroxide cross-linking agents, fillers, and a three part stabilizing system.
