VESPEL® SP-1

Vespel® SP-1 is an unfilled polyimide grade offering reliable performance for machined parts that need to operate at temperatures ranging from cryogenic levels to 300°C. In addition, Vespel® SP-1 can withstand brief temperature excursions up to 482°C because it has no Tg or melting point measurable by standard methods. Maximum tensile strength and elongation at break and minimum thermal conductivity coefficient. Optimal dielectric properties.

Application examples: Mechanical and electrical parts subject to high temperatures, valve seats, seals, insulators.
