Abstract

L'invention se rapporte à des stabilisateurs de PVC contenant un mélange surbasique de sels tels que par exemple, des sels de magnesium et de zinc, d'acide benzoïque non substitué et/ou à substitution alkyle et, éventuellement, un ou plusieurs acides aliphatiques gras, qui contiennent un stabilisateur au carbonate et/ou au silicate et qui, de préférence, contiennent un ou plusieurs polyols dont le nombre de groupes hydroxyle est compris entre 2 et 10. L'ensemble offre une réduction appréciable et inattendue en ce qui concerne la tendance à la volatilisation et la formation de brouillard lors d'une exposition à des températures modérément élevées, sans disparition par ailleurs des autres propriétés de stabilisation souhaitables.
