Thermoseal® RG-S140
Thermoseal RG-S140 is a controlled-swell gasket material that provides excellent sealing where initial gasket conformability is required to compensate for flange out of flatness or roughness. After establishing initial sealability, the styrene butadiene binder fully vulcanizes with time and heat of component operation to provide long lasting performance. RG-S140 contains a unique blend of aramid, mineral, and cellulose fibers as well as mineral fillers to provide enhanced crush and temperature resistance. A factory applied release coating on both sides aids in flange removal. Continuous roll lengths allow efficient and economical fabrication with high speed die cutting equipment. Typical applications include gaskets for sealing hot oil or coolant in machinery including small engines and automotive and heavy duty diesel engines with intermittent operating temperatures up to 550° F (288° C).
