DuPont Mobility and Materials Vespel® SP-211 Polyimide, 15% Graphite, 10% Teflon® Filled, Machined
Categories:	Polymer; Thermoplastic; Polyimide, Thermoplastic
Material Notes:	Has lowest coefficient of friction over wide range of operating conditions. Also, has lowest wear rate up to 300°F. Applications: For low friction and wear applications in moderate temperature and PV environments. Bearings (bushings, washers, etc.). Direct-formed properties were measured perpendicular to the forming direction unless specified. Machined properties are non-directional Information provided by DuPont Information provided by DuPont. This product line has remained with DuPont after the DuPont-Dow merger.
