Westchester Plastics

Westchester Plastics is the nation's leading independent toll compounder of engineering resins, alloys, blends, reactive modifiers and other thermoplastic materials. From a vantage point spanning over five decades in the plastics industry, we've seen and influenced many of the technological developments leading to today's advanced processes and materials.

Westchester Plastics began in Westchester County, New York, in 1948, as a small, privately held resin processor with ambitious growth plans. Over the years, Westchester Plastic's reinvestment in personnel, equipment and technology helped position the company as a leader in processing a wide range of advanced thermoplastic resins, alloys and color concentrates.

In 1968, Westchester Plastic's growth accelerated with the company's acquisition. That event provided an infusion of financial and technological resources to help us realize new market-exploration and facilities-expansion goals.
