The plastics pyramid below is an at-a-glance plastic material selection guide. Every application has unique material characteristic requirements for temperature, strength, cost and more. We use the broadest range of injection molding plastic resins, including commodity, engineering and high-performance grades such as Torlon, PEEK, Polysulfone and Polyphenylene Sulfide. Diversified Plastics, Inc. is here to help you select the right plastic for your application.
