common, conventional plasticizers, others have a need for feedstock growth. To meet this need, suppliers of bio-succinic acid, which is used to make succinic ester plasticizers as well as other materials, have announced planned capacity increases. BioAmber, which operates a dedicated bio-succinic acid plant in Pomacle, France, has broken ground in Sarnia, Canada on a 17,000 tonnes/year bio-succinic acid plant that is projected to start up in late 2013. The operation is a JV with Mitsui and is co-located with a Lanxess facility. Lanxess and BioAmber worked together to develop a new family of bio-succinic acid based plasticizers, which were introduced in late 2012 and are marketed by Lanxess under the Uniplex LXS TP brand. Myriant is currently in the process of commissioning


a new, 30 million pound (13,600 metric tonne) bio-suc- cinic acid plant in Louisiana, USA, with production expected to start this year. In May, Myriant announced the successful commercial production of biosuccinic acid at its engineering partner, ThyssenKrupp Uhde’s biotech commercial validation facility in Leuna, Germany. Galata introduced Drapex Alpha 200C, an addition to its series of natural oil-based primary plasticizers, fi rst introduced in 2012. The new bio-based product is designed for white and clear PVC compounds and specialty applications. PVC compounds with the new plasticizer exhibit improved extraction resistance, reduced volatile organic compounds, and enhanced processability, the company says. Late last year, PolyOne introduced the reFlex 300


bioplasticizer, which is certifi ed under the USDA BioPreferred program to contain 99% bio-based content. The new, non-phthalate plasticizer can directly replace general-purpose plasticizers, such as DINP, used in fl exible vinyl formulations. Earlier last year, PolyOne introduced the fast-fusing reFlex 100 bioplasti-

cizer, designed to replace benzoates and lower molecular-weight plasticizers such as BBP. The bioplasticizers were developed as a result of a develop- ment alliance between PolyOne and Archer Daniels Midland (ADM). A partnership between Petrom (Brazil’s Petroquimi-


ca Mogi das Cruzes) and Proviron (a Belgium-based chemical company) has resulted in the Proviplast PLS Green products, which are epoxidized fatty acid alkyl esters used as primary plasticizers for PVC. Proviron is marketing the products in Europe and Asia, and


Petrom is targeting other markets. Proviplast PLS Green 5 has 100% bio-based content and is made from an iso-amyl epoxy stearate, and PLS Green 8 has 68% bio-based content and is made from 2-ethylhexyl epoxy stearate. Applications for these products include artifi cial leather, PVC laminates, toys, coated materials, and food-wrapping fi lms. In a transparent paste PVC, for example, Proviplast PLS Green showed improved thermal stability, ageing, and rheology characteristics compared to general-purpose phthalate plasticizers, Proviron reported at the AMI PVC Formulation Conference.
