Extraction resistance of Galata Chemicals’ Drapex Alpha 200E bio-plasticizer compared with more traditional types


Segetis says that the volatility of its SGP9200 plasticizer is closer to the phthalates than the other fast fusers. Volatility of neat plasticizers measured by TGA – ramp 10˚C/min to 130˚C and hold for 1 hour


viability, high effi ciency, low extractability, enhanced processability, low volatility, low in-process colour development, excellent antimicrobial resistance, and electrical properties.” Lanxess is another major in phthalate-free plasticiz-


ers. Its key products include Mesamoll, Adimoll, Ultramoll, Unimoll and Uniplex. Lanxess has worked with – and invested in – BioAmber, a producer of bio-based succinic acid, to co-develop a family of bio-based succinate plasticizers. Segetis is relatively new to the scene, having been


founded in 2007 near Minneapolis in the US. It has attracted venture capital from various investors, including DSM and SABIC. Segetis has developed a range of plasticizers based on levulinic ketals derived from levulinic acid, which is formed by hydrolysis of cellulose. The US Department of Energy lists levulinic acid among its 12 “Top Value Added Chemicals From Biomass.” According to Segetis market strategy leader Dorie


Yontz, the company currently uses sugars as feedstock, but in the long-term it expects to be able to switch to various cellulose streams that do not compete with the food chain. “Our products are made by thermochemical processes rather than fermentation processes,” she says. “Therefore, we have the chemical simplicity, scale-up ease, capital, and purity of traditional chemical processes with the benefi t of renewable feedstocks. We are not tied to a specifi c crop, so we have tremendous feedstock fl exibility.” The company now has a demonstration plant for the


plasticizers (as well as a pilot plant producing the acid), but full-scale production of acid and plasticizers is

scheduled for 2016. Segetis already has REACH registration for the chemicals. First in the range is a fast-fusing grade, SGP9200, suitable for plastisols, which Yontz says has lower volatiles than other fast-fusing alternatives. Plasticizers for general purpose applications and for wire and cable are in development.
