ers. The company says all of its plasticisers are available as bio-attributed versions using the ISSC PLUS mass-balance allocation system.

process due to its low viscosity and good gelation performance. Volatility is on a similar level to Evonik’s well-established Vestinol 9 diisononyl phthalate (DINP) – Figure 2. The new plasticiser is said to be particularly suitable for demanding outdoor and indoor applications such as textile fabrics, roofing mem- branes, floor coverings, adhesives and sealants as well as paints and varnishes – Figure 3. Elatur DINCD fits with Evonik’s long-term
strategy to expand its portfolio of plasticisers to meet specific customer needs, according to Director of Marketing for Plasticisers Janina Fischer, who says it “complements our existing and proven product family.” The plasticiser will be produced at Evonik’s

site at Marl in Germany. An initial production campaign has already been successfully carried out. Production will be expanded step-by-step, in response to market demand, the company says, adding that it is taking additional steps in its C4 Verbund (integrated supply chain) to further strengthen supply security and the availability of all plasticisers. Elatur DINCD is offered alongside Evonik’s Elatur CH and Elatur DPT fast fuser plasticis-

Extended portfolio Bio-based Drapex Alpha primary plasticisers have been available from Galata Chemicals for several years and the company continues to extend the portfolio. It has established grades for calendered compounds and plastisols — Drapex Alpha 200 and Drapex Alpha 215 respectively. The latest addition to the range is Drapex Alpha 250, a non-GMO bio-based plasticiser grade manufactured from renewable feedstocks non-related to the food supply chain. According to Peter Frenkel, Vice President
Technology at the company, the Drapex Alpha plasticisers “consistently demonstrate their excel- lent extraction resistance, low volatility and low smoke generation as well as resistance to microbial growth while imparting low-temperature flexibility, enhanced processability and heat stability.” He says a completed cradle-to-gate Life Cycle Assessment (LCA) shows incorporation of the plasticisers results in substantial reduction in Global Warming Poten- tial (GWP) of PVC compounds. Galata has also developed a range of high
efficiency heat stabilisers, such as Mark 3600, which are designed specifically for use in compounds plasticised with the Drapex Alpha plasticisers. “This type of bio-based plasticiser/stabiliser combina- tions [provide] substantially extended long-term heat stability at stabiliser loadings reduced by up to 50-80% compared to compounds stabilised with the conventional Ca/Zn stabilisers and plasticised with the conventional plasticisers,” says Frenkel. Two bio-based plasticisers were recently added

to the Valtris product line-up. Santicizer Platinum G-2000 is based on soybean oil sourced in North America and is marketed in North and South America. Santicizer Platinum G-2030 is based on EU-sourced rapeseed oil and will be offered in Europe and Asia Pacific. Both plasticisers are claimed to provide an 85% renewable carbon content. The company has completed LCAs to ISO 14040 and ISO 14044 on both products, conducted
according to the LCIA EN 15804 + A2 methodology. Key results of
