Meldin® 7001 Polyimide - Unfilled
Meldin® 7001, Unfilled Polyimide Rods & Plates
A thermosetting polyimide, Meldin® 7001 is made from the unfilled base resin. This grade offers the maximum mechanical properties and high chemical resistance. The Meldin® 7001 grade is ideal for electrical and thermal insulating applications. More ductile than ceramics, and lighter weight than metals, Meldin® 7001 is a popular choice for structural parts in aerospace and other applications where metal replacement is desirable.
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. The 7001 grade is suitable for high-temperature structural, high-purity semiconductor, and welding component applications.
Meldin Plates are Compression Molded. Meldin Rods are Isostatically Molded (ISO).
Meldin DF Parts are Direct Formed. Please see the approrpriate technical data sheet for the shape/composition that you are purchasing.
Applications:
Wafer Clamping Rings, Plasma Torch Gas Distributor, Bearings, Seals, Insulators, Thrust Washers, Wafer Guides
When comparing price to Vespel, consider that Meldin's 12" x 12" plate has 44% more material than Vespel's 10" x 10" plate.
