  • Patent number: 9153377
    Abstract: The invention relates to a hot melt dispensable polymeric composite and process for making and using the composite. Particulates of adequate particle size are mixed with a polymer that exhibits low viscosities at temperatures typically provided by hot-melt glue guns to form rods that vary significantly in density from the base polymer. Novel articles can be manufactured by dispensing the composite from a glue gun into molds or by placement of the melt molding compound into preformed cavities within an end article.
