Meldin® 7021 Polyimide (15% Graphite Filled)

Meldin® 7021 features a 15% (by weight) graphite self-lubricating filler encaspulated by the base Polyimide resin.

This material has a low coefficient of friction and high heat resistance, making it an excellent choice for high temperature bearings, seals, thrust washers and other low-wear applications.

Meldin® 7021 provides consistent mechanical and performance properties for aircraft airframe systems such as landing gear and fuselage components, as well as jet engine parts such as pads, bumpers, washers, seals, and bearings.

MELDIN® 7021, Polyimide with 15% by Weight Graphite Filler (comparable to vespel SP-21 polyimide).

Our 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, MELDIN® 7021 provides our customers the best all-around choice for high temperature bearings, seals, and other low-wear applications.
