Stabilisers
Stabilisers are added to PVC to allow its processing and to improve its resistance especially in outdoor applications, weathering and heat ageing and have an important influence on the physical properties of PVC finished articles.
Factors such as process technology involved, technical requirements of PVC end product, regulatory requirements and cost, influence the choice of the stabiliser used.
ESPA is a unique organisation representing three sub-associations:
The European calcium organic stabilisers association (ecosa)
Calcium-based stabilisers (including Ca-Zn & organic) for food contact, medical applications, and lead replacement.
The European liquid stabilisers association (elisa)
Liquid stabilisers used in a wide range of flexible PVC applications including sheets, flooring.
The European tin stabilisers association (etinsa)
Tin-based stabilisers used primarily in rigid applications including food contact use.
