PBT Granules

PBT Granules are a thermoplastic polyester resin available in granular form that exhibit good dimensional stability as well as chemical and heat resistance. With 14 size variations to choose from, PBT Granules can be injection molded into a wide array of industrial components and consumer products. Typical applications include automotive parts, electrical housings, gears, bearings, valves and food processing equipment. The granular form allows for convenient transport and processing.
