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-22 by DuPont
Designing with tight tolerances? Vespel SP-22 is the answer. When you have no room for error, Vespel SP-22’s minimal thermal expansion and dimensional stability give you the freedom to create exactly what you’ve imagined. Vespel® SP-22 has 40% graphite by weight for enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and stability against oxidation. 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.
