Abstract
The industry's commitment under Vinyl 2010 to phase out lead stabilisers by 2015 has generated market potential for more environmentally friendly stabiliser systems. The market volume for calcium/zinc and zinc free organic stabilisers is expected to increase strongly in the next 3–5 years. Most of these stabiliser formulations need costabilisers such as mineral acid scavenging additives. A new mineral additive, calcium aluminium hydroxyl carbonate, is described which is suitable for use as an acid scavenger for many PVC end applications. The performance of the new additive is shown to be acceptable in both zinc and zinc free systems using an organic core stabiliser. Screened applications include flexible PVC end uses such as sheeting and wire and cable, as well as rigid PVC applications including sheeting and profiles.
