Thermoplastic & Thermoset Piston and Sealing Rings-Image

Piston and sealing rings made in Meldin® thermoplastic 1000, 3100, 5000, and thermoset polyimide 7000 series materials offer excellent wear life and chemical compatibility versus traditional cast iron solutions.

Saint-Gobain Performance Plastics can produce various seal ring design types in these Meldin® material grades.

The Meldin® materials' excellent flexural, wear, frictional, and chemical properties make them ideal piston ring candidates for demanding applications such as compressors, vehicle transmissions and axles, hydraulic actuators, and shock absorbers. These materials can operate in completely non-lubricated environments and have proven their capabilities over many years of continued service in very demanding applications such as Compressed Natural Gas compressors.

Complex ring joint designs can be done economically in the Meldin® 1000 series, 3100 series, and 5000 series materials due to the fact that these materials are injection molded.

In addition, Meldin® materials are lightweight, which makes them excellent material choices for improving vehicle weight in automotive and other vehicle applications.
