Dupont Vespel Polyimide SP-1 sheet rod

vespel® SP Polyimide shapes (Vespel Sheet and Vespel Rods) manufactured by DuPont ,We supply all Vespel SP grades in Sheets, Rods and finished Parts. 

Vespel® polyimide is available in five standard grades:

Vespel® SP-1 - Unfilled. Maximum strength & elongation: lowest modulus & thermal conductivity: optimum electrical.

Vespel® SP-21 - 15% graphite (by weight). Enhances inherent wear resistance, improves long term thermal stability.

Vespel® SP-22 - 40% graphite (by weight). Gives low coefficient of thermal expansion. Maximum creep resistance.

Vespel® SP-211 - 15% graphite and 10% PTFE® fluorocarbon resin (by weight). Lowest static friction.

Vespel® SP-3 - 15% MoS2 (by weight). Best wear performance in dry environments.

Trustworthy under extreme conditions

Vespel® parts and profiles are suitable for harsh industrial operating environments

Tensile testing of machined parts used in extreme conditions.

Extreme temperature, high friction and heavy load? Since 1965, Vespel® has performed better than other engineering materials under harsh conditions.

Demanding applications such as aerospace components, semiconductor processing, automotive manufacturing, and energy production rely on Vespel® parts to keep their equipment running.

Vespel® polyimide material can operate continuously from low to high temperature; In lubricated or unlubricated environment, low wear and low friction under high PV; Excellent creep resistance, high strength and impact resistance; Excellent Dimensional stability; low thermal expansion coefficient; and ease of processing.

Vespel® makes parts lighter not only feasible, but in many cases superior to general-purpose metals, ceramics and other engineering polymers, such as PEEK (polyether ether ketone) and PAI (polyamide-imide)).

In design centers in Asia, Europe and the Americas, DuPont technicians work with customers to combine material science and design to produce high-performance parts and keep production running smoothly.

Vespel® components and profiles (regardless of custom or conventional specifications) have been tested, tested and proven reliable in demanding applications around the world. They have plates, rods, tubes, squares, strips, discs, rings, spheres and custom machined parts
