Saint-Gobain's Polymer Product's in-house manufacturing capabilities range from compounding or producing Rulon® and Meldin® materials, to auto molding, injection molding, and direct forming of these and many other high performance plastics (PTFE, polyimide, PPS, PEEK, PPA, etc.).
Piston rings and sealing rings made in Meldin® 1000 series, 3100 series, 5000 series, and 7000 series materials offer excellent chemical compatibility and wear life compared to traditional cast iron solutions. Saint-Gobain Performance Plastics can produce various joint detail design types in these Meldin® material grades.
The Meldin® materials’ excellent flexural, wear, frictional, and chemical properties make them ideal piston rings or sealing ring candidates for demanding applications in such equipment as compressors, vehicle transmissions and axles, hydraulic actuators, and pneumatic power tools, to name a few.
Meldin® gear components are well suited for motorsport and vehicle applications, industrial pumps, and more. The ability to injection mold the Meldin® thermoplastic grades enables us to produce an economical gear part, with minimal post machining. Gear components include spur gears and gerotor element sets, both of which lend themselves to various pump applications.
The Meldin® materials’ good rigidity and high flexural modulus properties, as well as a unique combination of wear resistance and ability to allow foreign particles to embed into the Meldin, make them ideal materials for gears or gerotors.
