Specialty dispersions of antioxidants are commonly used as chain-stoppers in the polymerisation of PVC in order to allow higher production efficiency by terminating the free radical reaction at the desired conversion level. They also can significantly improve the whiteness of the PVC because the Antioxidant is intimately incorporated in the polymer during the polymerisation.
Aquaspersions has a continual development programme in place to ensure that new products are available to meet the needs of our customers. A particular area of focus recently has been the improvement of the PVC whiteness after dynamic ageing, ie shear and heat.
All our products are completely free of ionic surfactants and offer cost-effective high performance.
