Plastics Materials
Materials used in plastics processing include plastics, thermoplastics or polymers, materials are the stuff of which molded and extruded parts are made. Broad subcategories include commodity materials such as polyethylene, polypropylene and PVC; and engineering materials such as nylon, acetal and ABS for applications requiring higher performance.
