Vespel® SP-3 is 15% moly-filled (milybdenum disulfide solid lubricant) for wear and friction resistance in vacuum and other moisture free environments where graphite actually becomes abrasive. Typical applications of Vespel® SP-3 include seals, bushings, bearings, gears, and other wear surfaces in outer space, ultra-high vacuum or dry gas applications.
