biomass balanced plasticisers only in accordance with the REDcert2 certification scheme. Since June, its biomass-balanced plasticisers are also certified to the ISCC Plus certification scheme. Better meeting customers’ needs is the driver
for expansion of the plasticiser product range at Evonik Oxeno, the company says. Its latest innovation in the sector is the specialty plasticiser Elatur TM, which has been developed for demand- ing applications such as high temperature cables, dashboards, car seating parts and high-quality interior fittings including steering wheel trim. “The portfolio expansion is in line with our

performance in both PVC and in bioplastic resins. They can be used as single plasticisers, in combina- tion with each other, or in conjunction with other plasticisers. Both are biodegradable.
Mass-balance approach Germany’s BASF has been using a biomass-bal- anced (BMB) approach for its Hexamoll DINCH BMB, Palatinol N BMB, Palatinol 10-P BMB and Plastomoll DOA BMB plasticisers since 2020. Further supporting its circular goals, the company recently expanded its BMB portfolio with Plasto- moll DNA and the polymeric grades Palamoll 652, 654 and 656 in a BMB version. “Customers are focusing on smart ways to

reduce the carbon footprint in their formulations,” says Ellen Strubel, Head of Sales Plasticisers EMEA at BASF. The company says that using biomass- balanced versions of known plasticisers means customers can realise a reduced carbon footprint through the attribution of renewable raw materials within BASF’s integrated production system. Such plasticisers offer the same product features as their conventional counterparts, so they can be used and processed in the same way. Calculation of the product carbon footprint (PCF) follows the “Together for Sustainability” methodology, in which BASF and several other chemical companies have agreed on a global guideline with the goal of assessing, auditing, and improving sustainability practices within their global supply chains. TÜV Rhineland has certified that BASF’s method to calculate cradle-to-gate product carbon footprint is in line with the relevant ISO standards and with the Greenhouse Gas Protocol Product Standard. Prior to June of this year, BASF offered its

expansion strategy with the latest generation of isononanol (INA)-based plasticisers,” says Roland Pietz, Market Segment Head for Oxo-Alcohols and Plasticisers at Evonik Oxeno. He says the product launch strengthens Evonik’s business in the PVC plasticiser sector. The Elatur TM introduction further extends
Evonik’s Elatur product line, which comprises the Elatur DINCD and Elatur CH (DINCH) general purpose plasticisers for outdoor and indoor applications, and Elatur DPT fast gelling plasticiser. The company’s portfolio also includes Vestnol 9 (DINP), a high molecular weight universal plasti- ciser that the company says is suitable for almost any flexible PVC applications. Evonik Oxeno’s ISCC Plus certification means it can use mass balance methods to offer grades that can be attributed as bio-based, circular, bio-circu- lar, or reduced-footprint. The company also recently developed its myFlexino portal, oroviding customers with 24/7 access to relevant technical documents and supplementary information, including online sample request. Poland’s Grupa Azoty has for some time focused its plasticiser developments and business on non-phthalate grades, introducing its first non-
