The National Rubber Corporation was founded by Perry Monpara in 1997, just outside of Pittsburgh, Pennsylvania. After working in the industry for a few years, Perry started up National Rubber. National Rubber started off as a small custom extruded rubber product shop with a 2,800 square foot facility. Since then, National rubber has had two major expansions and currently operates out of a 65,000 square foot facility with capabilities including standard and custom extrusion, compressor molding, transfer molding, injection molding, splicing, and die-cutting gasket material.
