ALBANY, N.Y. (Dec. 20, 2011)—Momentive Performance Materials Inc. said that its NXT X 45 silane was used by Sumitomo Rubber Industries Ltd. on its new Enasave Premium-brand tire.
Sumitomo launched the tire at the Tokyo Motor Show, held Dec 2-11. The Enasave Premium received the highest rating for rolling resistance under the Japan Automobile Tyre Manufacturers Association's labeling system and is the flagship tire in its Enasave fuel-efficient tire series.
Momentive said the tire is the first to use the NXT Z 45 silane, a coupling agent for silica-based tire tread compounds that the materials supplier claims gives improved dynamic and physical properties, including rolling resistance and wet traction. The firm added that the silane can virtually eliminate the ethanol that is released during the manufacturing and use of silica tires.
