DESCRIPTION
A fiberglass reinforced thermosetting compound manufactured by dispersing long stands (>1”) of chopped glass fibers on a bath of polyester resin. The longer glass fibers in SMC result in better strength properties than standard BMC products. Typical applications include demanding electrical applications, corrosion resistant needs, structural components at low cost, automotive, and transit.
