Parts made from DuPont™ Vespel® SP-2515 offer a low coefficient of thermal expansion (CTE), excellent wear against both aluminum and steel alloys, and a low coefficient of friction in both dry and lubricated conditions. These properties make Vespel® SP-2515 parts ideal for applications such as seal rings, thrust washers, and bushings where high energy efficiency and dimensional stability, over a broad range of temperatures, are a requirement.Information provided by DuPont.
