Use and possibilities for substitution of cadmium stabilizers.
Of all plastics, Polyvinyl chloride is the only product stabilized with cadmium compounds, and then only to a certain extent. The amount of cadmium used as stabilizers is approximately 15% of the world production. The general importance of stabilization in view of ecotoxicological problems is discussed, leading to a more detailed consideration of the specific sectors in which plastic materials are used. Stabilization is strongly connected with the intended application and processing technology. It is obvious that stabilization of rigid PVC is indispensable in outdoor applications. If, at present, no substitute for cadmium stabilization is available, it is emphasized that the industry is strongly interested in resolving the problem, i.e., in searching for a cadmium-free stabilizer, for economic as well as environmental reasons.
