The high cost-to-performance ratio has limited the common use of Calcium-Zinc stabilisers in other general applications where heavy metal based systems are permitted. However, with continued advancements in formulation technology, the performance of the new generation Calcium-Zinc stabilisers has improved substantially. Today, Calcium-Zinc stabilisers can effectively replace and compete with other common heavy metal based stabilisers in many processes for rigid and flexible PVC products.
The PVC industry trend is accelerating the phasing out of heavy metal stabilisers. This is driven by voluntary measures and new legislative regulations to achieve sustainable growth. Examples include the implementation of the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) Directive and Vinyl 2010 - Voluntary Commitment of the PVC industry in Europe to phase out Lead stabilisers by 2015. In line with these developments, Calcium-Zinc system solutions have become the preferred choice worldwide.
