susterra_logo DuPont Tate & Lyle Bio Products today announced that it granted Nam Liong Enterprise Co., Ltd., a license to use its corporate brand with Nam Liong’s Ureamax® Plus TPU films. Ureamax® Plus is used as a membrane in the manufacturing of waterproof and/or breathable textiles and contains a minimum 20 percent by weight of Susterra® biobased propanediol. The brand license can also be used in its Enprotex® Plus waterproof and/or breathable woven fabrics containing at least 20 percent by weight Susterra® content in the TPU or PU-based resin.

Susterra® propanediol is certified 100 percent biobased by the U.S. Department of Agriculture, making it attractive for companies seeking to add renewable content to their products. A peer reviewed life cycle assessment (LCA) demonstrates that the production of biobased propanediol offers significant environmental benefits including up to 40 percent less greenhouse gas emissions and 40 percent less non-renewable energy used in its production vs. petroleum-based glycols.

"We are proud to be working with Nam Liong on this exciting new Susterra® application that brings renewably sourced, environmentally friendly, high-performance products to market. Our goals are perfectly aligned; it's a great partnership," said Todd Sutton, president of DuPont Tate & Lyle Bio Products.

"Innovation from using the Susterra® biobased material for Nam Liong’s Ureamax® Plus TPU membranes and Enprotex® Plus fabrics creates new business development opportunities in more applications such as outdoor jackets and gloves, sport leisure shoes and bags, medical protective wear, life jackets, etc. Nam Liong not only attracts recognition from the leading brands and manufacturers for its innovation but the company also is recognized for its commitment to environmental caring, including energy savings and carbon footprint reduction," commented Ting Kuo, vice general manager of Nam Liong
