Kraton Polymers Announces Breakthrough Technology in Sulfonated Copolymers



Kraton Polymers LLC (Kraton), a leading global producer of engineered polymers, introduces the latest innovations in sulfonated copolymer technology. The new products, KRATON MD9150 and MD9200, allow for remarkable performance in ion exchange and high water transport applications, while providing a cost savings over current alternatives available on the market.

KRATON MD9150 and MD9200 are selectively midblock sulfonated copolymers providing excellent performance in water vapor transport, chemical resistance, selective gas permeability and ion-exchange properties, as well as strong mechanical performance in both wet and dry environments. These unique key properties allow Kraton to serve various industry segments with one product line that is offered in Ion Exchange Capacity (IEC) levels of 1.5 and 2.0 (meq/g) respectively.

Kraton's advanced new copolymers are offered both in membrane and solution form, giving the designer the flexibility to create unique shapes and coatings/laminations. These new sulfonated copolymers offer the customer a greener solution by reducing the processing temperatures as compared to current technology.

Kraton's sulfonated copolymers are designed for applications in desalination, electrodeionization, electrodialysis, humidification and dehumidification, breathable protective clothing, battery separators, fuel cell membranes, sensors and actuators, reverse osmosis, medical devices, filtration, gas separation, performance outerwear and apparel, energy recovery and antifouling.

Lothar Freund, Vice President of Technology states "Our scientists have designed a novel block copolymer structure that gives a unique morphology for high water transport while maintaining interesting gas and ion perm-selectivity. These cutting-edge products demonstrate our continued commitment to bringing advanced innovations and value to our customers." Kraton will unveil the branding program for this new product family in early 2009.
