Materials catalog introduces a line of high-temperature polyimides. A series of polyimides can be processed by direct forming, a molding method similar to that used in powdered metallurgy. The Meldin 7000series 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.

. A series of polyimides can be processed by direct forming, a molding method similar to that used in powdered metallurgy. The Meldin 7000series 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 7000series 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. Manufactured by Saint-Gobain Performance Plastics (Bristol, RI; 401/253-2000), the polyimides are available in two grades: unfilled 7001 and 15% graphite-filled 7021. The 7001 grade is suitable for high-temperature structural, high-purity semiconductor, and welding component applications, while the 7021 grade is efficient in stable, low-weight bearing and guideway applications.
