Roquette has been rewarded with the 2009 Pierre Potier prize for its POLYSORB® ID 37, a high-performance plasticizer produced from natural products, and it continue sto work further in the development of vegetal-based chemistry.
POLYSORB® ID 37 is a composition of isosorbide diesters produced from fatty acids of vegetable origin and isosorbide obtained by simple modification (dehydration) of a derivative of glucose, sorbitol. POLYSORB® ID 37 is totally produced from renewable (bio-based) natural products. It is non-toxic and biodegradable. It constitutes, thanks to its plasticizing properties equivalent to the products on the market, an alternative to the phthalates conventionally used for the manufacture of flexible PVC (polyvinyl chloride).In relation to the other phthalate-free plasticizers (adipates, acetylated monoglycerides, citrates) it is particularly versatile and has both excellent compatibility with PVC and a very low volatility. The first step towards the industrialisation of isosorbide diesters has just been completed with the recent obtainment of the European authorisation to produce significant volumes. To back up the development of this product, Roquette launched in June 2008 in Lestrem (France), a demonstration unit for production with a capacity of over 100 tpa. This investment follows on from that made in 2007 to build an industrial isosorbide unit with a capacity of over 1000 tpa and confirms Roquette's strategy of promoting sustainable development.
