Roquette is Increasing Production Capacity of Isosorbide

Published on 2010-09-16. Author : SpecialChem

Roquette announced that its production capacity of Isosorbide located in Lestrem (France) will attain several thousand tonnes by the beginning of 2011, at the "Bio-Based Chemicals East" congress in Boston, MA, on 13 September 2010. Roquette is consolidating its position as world leader for Isosorbide, a biobased intermediate for new polymers and plasticizers.

Isosorbide is a diol obtained by dehydration of sorbitol

Isosorbide is a diol obtained by dehydration of sorbitol, (a derivative of glucose), -for which Roquette is the leading world producer. Isosorbide is used for the manufacture of specialty polymers in the polyester, polycarbonate and polyurethane families. Thanks to its rigid structure, isosorbide is the only biobased diol that improves resistance to heat, UV rays and chemicals, and offers excellent optical and mechanical properties on the materials produced.

Roquette has been marketing POLYSORB® P, a high purity grade isosorbide especially tailored to the manufacture of polymers for the last several years. These patented technologies have enabled Roquette to establish several collaborations with major participants in the polymer field, such as the Mitsubishi Chemical Corporation, which is developing a new specialty performance polymer including POLYSORB® P as an essential constituent.

Roquette has also developed POLYSORB® ID 37, a 100% biobased isosorbide diester, which has excellent plasticizing properties for PVC, inks and varnishes. Roquette received the 2009 Pierre Potier Prize for "Chemistry for Sustainable Development" in France for POLYSORB® ID 37 which enables elimination of phthalate plasticizers.

With Isosorbide and its derivatives, Roquette is putting on the market a whole range of biobased derivatives that can not only replace suspect molecules such as Bisphenol A and phthalates but also endows remarkable additional properties in selected polymers. This achievement is part of Roquette's overall strategy of sustainable innovation with its two major creative areas: Nutrition-Health and Vegetal based Chemistry.

About Roquette

The Roquette group family enterprise is one of the top-ranked processors of starch (N° 2 in Europe and N° 4 in the world), as well as being the world leader in polyols, pyrogen free raw materials and dry sugars. In 2007 it achieved a turnover of over 2.5 billion euros.

Roquette basically converts four vegetables into raw materials essential to industry. As a result, thanks to the starch extracted from maize, wheat, potatoes or peas, the firm produces more than 650 by-products.
