WHAT IS SIMSITE? Simsite is a graphite-fiber reinforced composite material manufactured by the Sims Pump Valve Company. Simsite is a heavy duty structural composite laminate material which must be machined to create such parts as impellers and casing rings. Specifically, it is a graphite combination-fiber reinforced composite material with phenolic resin. Depending on the application, the fibers are interwoven in a bi-directional or tri-directional weave. The reinforcing fibers are all continuous for high strength. The Simsite composite consists of equal amounts of structural fibers and resin for high physical properties and a wide range of chemical resistance.
