O U R S P A C E A P P L I C A T I O N A R E A S
Building upon three initial unique designs (OmniSeal®, RACO™ and TEC Ring seals ), we have been recognized as a leading designer and manufacturer of high-performance spring-energized seals that provide improved sealing performance over soft elastomeric seals and hard metal gaskets in applications involving cryogenic liquid propellants in various rocket engine programs. Our Meldin® thermoset polyimide material is ideal as finished machined components in high temperature as well as a lightweight and dimensionally stable bushing, piston ring, guide ring, split ring type applications and other custom shapes.
