Diamond Polymers is more than a full service supplier of high-quality material. We pride ourselves on our ability to design a high quality thermoplastic material that is absolutely right for the demanding properties and characteristics that our customers require for their applications.

Diamond Polymers is the fourth largest producer of ABS and ASA in the United States and offers a full line of these resins and alloys. The company began in 1988 through a joint venture involving Network Polymers, Akron, Ohio, and Mitsubishi Rayon Company, Limited, and Marubeni Corporation of Japan. This partnership combined proven technologies and manufacturing capabilities that continue to produce a broad product portfolio of resins and alloys — all tailored to meet the specific needs of customers throughout the world. In 2002, Diamond Polymers became a wholly owned subsidiary of Network Polymers.
