The R.J. Marshall Company was founded by Richard J. and Joan E. Marshall in May of 1978. Originally conceived as a manufacturer representative company, R.J. Marshall sold commodity grade industrial raw materials. Soon, they found a way to offer a solution to the inconsistent quality of materials drawn from individual mines: a better way to achieve the best possible properties from batch to batch. This kind of consistency and quality has been the hallmark of the R.J. Marshall reputation even today. Offering a broad base of products to both the cast polymer and composites markets as well as the wire and cable industry, R.J. Marshall with its flame retardant and smoke suppressant division; Marshall Additive Technologies, and its subsidiary; Marshall Gruber Company, can service a full range of solutions to manufacturers for a variety of applications.
