Material Description

Vespel® is a high performance polyimide material which is formed from resin manufactured only by DuPont.  Polyimide materials are characterized by a ring-shaped molecular structure containing nitrogen and because of it’s high-performance polyimide offers a broad combination of temperature resistance, chemical resistance, mechanical toughness, natural lubricity, wear-resistance & insulation properties.  Vespel® is one of the highest performing engineering plastics currently available.  Vespel® will not melt and can operate continuously from cryogenic temperatures to 550°F (288°C), with excursions to 900°F (482°C).  Vespel® parts consistently exhibit superior performance in a variety of applications requiring low wear and long life in hostile environments.

Vespel® SP-3 is 15% moly-filled (molybdenum 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. Product listing does not imply any formal relationship between Professional Plastics and DuPont. DuPont certifications are non-transferable therefore material is provided with Professional Plastics certifications.
