<p>A heat stable molded phenolic resin article comprising, in percent by weight, from about 20 to about 70 percent of a phenolic resin, from about 3 to about 25 percent of an acrylonitrilebutadiene elastomer, and from about 15 to about 70 percent of a silicate mineral. Also a molding composition comprising, in percent by weight, from about 20 to about 70 weight percent of a phenol-aldehyde thermosettable resin, from about 3 to about 25 weight percent of an acrylonitrilebutadiene elastomer, and from about 15 to about 70 weight percent of silicate mineral.</p> |
