Partnership with Sundow Polymers C0., LTD

Sundow Polymers

Madison Polymer Additives and Sundow Polymers have agreed to an exclusive distributorship in the United States for chlorinated polyethylene.  Sundow's WELLPREN CPE produced using acid-phase technology provides environmentally friendly and consistent quality products.  Currently, Sundow has developed over 50 grades of CPE that can be applied in flexible and rigid plastic products, flame-retardant ABS, wire and cable, industrial and automotive hose, and magnetic rubber.  

In 2014, Sundow built a state-of-the-art acid-phase CPE facility in one of China's new chemical zones that were created to help combat pollution.  Acid-phase technology has many advantages over water-phase produced CPE but the primary advantage is the environmental impact.  Acid-phase CPE yields zero waste water in CPE production while water-phase CPE yields 25-30 metric tons of waste water per 1 metric ton of CPE produced.  Many of the water-phase CPE plants in China have been forced to shut down due to the incredibly high amount of waste water they produce.
