Suppliers of alternatives to lead- based stabilisers see opportunities to apply their expertise in areas such as Asia, while organics
Markets for PVC additives in the western hemisphere have been through some major changes in recent years, thanks most notably to moves in Europe to phase out lead-based stabilisers. That phase is over now, and a period of consolidation could be setting in. Additive suppliers that helped bring the changes about are now hoping that a similar feat may be accomplished elsewhere - lead stabilisers are still widespread in many regions, most notably across Asia. Some additive companies are also suggesting that organic stabilisers could well take a bigger share of the cake, providing alternatives to products based on metals such as barium and maybe even zinc. At the PVC Formulation 2017 conference organised
by Compounding World publisher Applied Market Information in Cologne in Germany in April, Reagens CEO Ettore Nanni discussed the drive towards more sustainable stabilisers. His presentation highlighted the four ‘sustainability principles’ set out by The Natural Step (TNS) NGO and the Additives Sustainability Footprint (ASF). Reagens claims to offer the broadest range of PVC stabilisers of any supplier, with a portfolio that covers calcium-organics, tin-based types, liquid soap stabilisers, and also lead-based stabilisers.

continue to gain market share. Peter Mapleston reports
Nanni described the ASF as “a new science-based
life cycle assessment framework combining existing ini- tiatives addressing environmental concerns with the four TNS [The Natural Step] System Conditions for sustainability.” In this assessment, cumulative contributions of all additives across the article life cycle are combined and presented as a colour-coded matrix. This identifies ‘hot spots’ (areas of concern) and benefits, and informs vinyl converters about innovation towards more sustainable formulations. “Reagens develops additives that contribute to a thriving and sustainable society through providing functionality (quality, durability, recyclability, etc) to PVC and other plastics that help support diverse human needs (for example, providing water, food, shelter, housing, etc) within the four TNS System Conditions,” he said. Nanni provided data on current consumption of various stabilisers around the world (much of it
