Vespel® is the trademark of a range of durable high-performance polyimide-based plastics manufactured by Dupont. Unlike most plastics, it does not produce significant out-gassing even at high temperatures, which makes it useful for lightweight heat shields and crucible support.
Vespel® is very useful in lightweight heat shields and crucible supports. It also performs well in vacuum applications down to even extremely low cryogenic temperatures. Other brand names include Meldin®, Tecasint® and Plavis®.
Vespel® is extremely resistant to high temperatures and creep and is often used in heat environments where thermoplastic materials lose their mechanical properties. Vespel®, a lightweight alternative to metal, is available in a wide range of formulations, including unfilled grades and very low friction and wear versions. It exhibits improved mechanical properties and superior thermal stability.
Vespel® products are highly durable polyimides for applications where exceptional thermal resistance, low wear and friction, strength and impact resistance are desirable. This high-quality polymer is mainly found in aerospace, semiconductor and transportation technology.
