Geometric Stability

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.

Powder-to-Parts

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.
