Vespel is a high performance polyimide material, which can operate continuously from cryogenic temperatures to 550 degrees Fahrenheit, with excursions to 900 degrees Fahrenheit. Vespel parts exhibit superior performance in a variety of applications requiring low wear and long life in severe environments. Vespel, unlike most plastics, is non-flammable. Parts perform without melting or softening, and resist radiation sterilization more effectively than most other plastics. Vespel parts exhibit a very low level of outgassing, even in high vacuum environments, and are chemically compatible with most fuels, solvents, lubricants and hydraulic fluids. Vespel has above average tensile strength for a polymer, at 12,600 psi (pounds per square inch). Vespel will absorb 0.24% of its weight when exposed to water for 24 hours. Vespel is extremely impact resistant, rated at 14 foot pounds (on the Izod Impact Scale), which compares favorably against Nylon 6/6 at 3 foot pounds. Vespel also has excellent insulating properties, measured in terms of dielectric strength, with a rating of 260 volts/millimeter.
