35 MPa
Meldin® Polyimides
7000 PI Based
A thermosetting polyimide, the Meldin® 7000 material series exhibits extremely high dimensional stability at elevated temperatures. Testing has shown that Meldin® materials have less than 0.04% variation from their original dimensions after cycling from 73°F (22.77°C) to 500°F (260°C) over a two-day period.

Meldin® Polyimides
8000/9000 PI Based
The Meldin® 8000/9000 Polyimide (PI) Based series is a specific range of material formulations, used in bearing cages, for example, due to its strength and its low coefficient of friction. It is a porous structure filled with lubricant.

Spring-Energized Seals
Polymer Seals with Metal Springs
Omniseal® spring-energized seals are composed of two precision parts: a PTFE or polymer jacket and a corrosion-resistant, metal energizer spring. With an unlimited shelf-life compared to conventional seals, the precision seals provide improved performance over soft elastomeric seals and hard metal gaskets that typically fail. Engineered spring designs include: ribbon or helical seal design; cantilever or V-spring seal design; U-shaped seal design; and advanced pitch spring or coil seal design.
