Compositions are disclosed containing an elastomer, particulate polytetrafluoroethylene and an amount of molybdenum disulfide effective to permit their manufacture. The particulate polytetrafluoroethylene may include amounts from 25 percent by weight to 80 percent by weight, and/or include small amounts of fibrillated polytetrafluoroethylene. Also disclosed are additives for such compositions, and methods for preparing such compositions and additives using polytetrafluoroethylene and molybdenum disulfide, and improved compositions and products. Compositions and products of the invention can also be provided with the advantages of many of the unique properties of polytetrafluoro- ethylene combined with the advantageous properties of elastomers. Among the properties of PTFE that may be realized in such compo- sitions and products are chemical inertness and stability, insolu- bility, heat resistance, electrical insulation and surface lubricity and abrasion resistance, and these properties may be incorporated into an elastic article or product.
