Meldin 7000 Series
Meldin 7000 series
Geometric Stability at High Temperature
7000 series materials exhibit extremely high geometric stability at elevated temperatures. Testing has shown Meldin 7000 to have less than 0.04% variation from its original dimensions after cycling from 22.77ºC (73ºF) to 260ºC (500ºF) over a 2 day period.
Longer Life at Higher Loads and speeds
The self-lubricating grades of Meldin 7000 do not melt when exposed to high load (P) or high speed (V) applications, as compared to more traditional PTFE or thermoplastic polymers. PxV limits for Meldin 7000 self lubricating grades exceed 300,000 in dry environments and past 1,000,000 in liquid or grease lubricated environments.
Meldin 7001 Unfilled Grade
A thermosetting polyimide. MELDIN 7001 is an unfilled 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 7021 Self-Lubricating Grade
A self-lubricating grade, MELDIN 7021 has 15% by weight graphite fillers, encapsulated by the base polyimide resin. With its low coefficient of friction and high heat resistance (up to 482ºC [900ºF]), MELDIN 7021 provides customers with the best all-round choice for high temperature bearings, seals, and other low-wear applications.
