Adding stability to vinyl compounds
The market for PVC additives supply is changing. In recent years there has been a shift in manufacturing from giant chemical producers to smaller companies that are well positioned to move rapidly with technology development. Anticipating market needs helps this new generation of suppliers to stay ahead of the curve – and their competitors. Large corporations still supply additives, of course,
but many are dropping out of the market or scaling back operations to focus on larger-volume chemicals and higher-priced specialities. Companies that have recently divested all or part of their PVC additives businesses include AkzoNobel, Arkema, Chemtura, Dow Plastics and the Hammond Group. Their successors – which have bought either
business units from the majors or been spun off from them – are becoming key suppliers in the market. They are committed to PVC additives, have clear visions and strategies for growing their businesses, and are seeking partnerships with compounders to develop formulations for current and evolving applications. This is having a big impact on materials. Most

Pat Toensmeier reviews the latest technical developments in PVC stabilizers as well as looking at
changes among the manufacturers and suppliers of such additives
suppliers say that the use of tailored formulations has exploded – from just 10-20% a few years ago, to as much as 80% of production today. Custom, moreover, does not necessarily restrict the availability of formula- tions. It often means that suppliers who develop special grades will eventually supply them to the entire market, thereby increasing additive selection.
Right on time It is a good time to be compounding PVC, since there have probably never been as many product choices
