Founded by Rex Bradt of Warsaw, IN, who invented the process for reinforcing thermoplastics with glass fibers. Bradt formed Fiberfil and marketed the first glass reinforced Polystyrene compound. He sold the company to Thomas Morton in 1955, who eventually moved it to his base of operations in Evansville, IN. Morton hired Bill Chadbourne, President of Danco, to run Fiberfil, and Chadbourne, brought Walter Lachowecki to Evansville to assist in building a business upon Bradt’s inventions.

The first application became U.S. ordinance-approved Styrafil, for use in non-magnetic land mines.

After 1955, the company manufactured Fiberglass Reinforced Thermoplastics (FRT) and by 1958, Fiberfil moved from a small laboratory (located in a barn near Warsaw, Indiana) to a small Warsaw, Indiana manufacturing plant. In 1963 the headquarters were moved to Evansville, and production began at a plant in Heidelbach. In 1968, a new plant is constructed on Outer St. Joe Ave. in Evansville.

In 1967 Fiberfil beames part of the Rexall Drug and Chemical Company, which changed its name to Dart Industries, Inc. in 1969. In 1970 Fiberfil International operations began with construction of a new site in Stoney Creek, Ontario Canada. In 1974 all plant operations are moved to modern facilities at the Northbrook site. Plastic Alloys was purchased in 1978, and this became the Fiberfil LaMirada facility, located in California.

By 1980: Fiberfil, as a member of Dart Industries, was engaged in the manufacture and marketing of plastics, chemicals, environmental services, housewares, packaging, architectural, pharmaceutical, health care and other similar products. Dart Industires merged with Kraft.

In 1981 Fiberfil merged with Wilson Products and becomes Wilson - Fiberfil International. Wilson Fiberfil was sold to a group of investors in 1984, who form PS & T. In 1986 Wilson Fiberfil is purchased by Akzo, and in 1989 the company name is changed to Akzo Engineering Plastics, Inc. In 1992 c is purchased by DSM. The company becomes known as DSM Engineering Plastics. DSM begins to implement strategies which focus on Specialty, High –End Application products.

In 2005 DSM Engineering Plastics Ltd. is purchased by Fiberfil Engineered Plastics Inc., and in 2009: Citadel Plastics Holdings Inc. purchased the assets of Fiberfil Engineered Plastics Inc.
