Neoprene is an important variety of synthetic rubber, not only has excellent light resistance, aging resistance, flexural resistance, acid and alkali resistance, oil resistance and heat resistance, but also has good physical and mechanical properties; its comprehensive performance is incomparable to other synthetic rubber. It is widely used in national defense, transportation, construction, light industry and military industry. Neoprene is mainly used in the production of automotive parts, machinery and industrial products and adhesives.
Based on the abundant knowledge in polymer chlorination technology and extensive word-wide distribution channels, from 2015, Sundow stepped into chloroprene rubber business, a SURPREN™ brand is created for chloroprene rubber under the agreement between Sundow and its partner.
SURPREN™ technology is introduced from Nairit, Amenia; this technology was originated from DuPont Neoprene rubber.
And now SURPREN™ is exported to more than 15 countries such as USA, Russia, Brazil, Argentina, Korea, Germany, Italy, Spain, Australia, and India etc.
