Meldin® 7000 Series is the latest polyimide range manufactured by ‘Saint Gobain Performance Plastics’ that offers extremely
high geometric stability at elevated temperatures. After cycling Meldin® 7000 from 22°C to 260°C over a 2 day period, tests
showed Meldin® 7000 to have less than 0.4% variation from its original dimensions.
The expanding resin production facility at manufacturer Saint Gobain Performance Plastics allows for total control of the quality and
source of the base polyimide resin. Meldin® 7000 compounds can be supplied as stock shapes, direct formed parts or finished machined components
to close tolerance dimensions.
Longer Life at Higher Loads and Speeds
Meldin® 7000 self lubricating grades do not melt when subjected to high speed (V) and / or high load (P) applications, as compared to
more traditional thermoplastic or PTFE polymers. Meldin® 7000 self lubricating grades exhibit P x V limits in excess of 10.5 MPa x m/sec
(300,000psi x ft per min)in dry environments and over 35 Mpa x m/sec (1,000,000psi x ft per min) in grease or liquid lubricated environments.
As a comparison, typical PTFE compounds have P x V limits in the range of 0.3 Mpa x m/sec.
