Meldin® 7022, 40% by weight graphite filler (comparable to Vespel® SP-22) - Meldin® 7022 is similar to the Meldin 7021 for wear and friction, but it has the best overall dimensional stability (thermally), and the 7022 has the lowest coefficient of thermal expansion – due to the relatively high graphite filler content.

Meldin 7000 series polyimides are formed using high-pressure mold presses, automatic resin-feeding systems, and computer-controlled hydraulics. Complex shapes can be molded, reducing the need for secondary machining operations. The Meldin 7000¡ series features operational temperatures of 600ºF for continuous operation and 900ºF for intermittent exposure, and tight tolerances of ±0.001 in. on both ODs and IDs.

Features of Meldin® 7022 Polyimide:
Excellent dimensional stability
Extremely low coefficient of thermal expansion
Meldin 7022 is an excellent replacement for Vespel® SP-22 from DuPont (compare and save)
Stocked in 12" x 12" plates (44% more material than a 10" x 10" plate)
Meldin® is a registered tradename of Saint Gobain
Vespel® is a registered tradename of DuPont
