Abstract: The invention relates to a plasticizing composition comprising a vinyl chloride resin and a plasticizing agent which comprises at least one diester having the general formula (I), derived from a diacid selected from succinic acid, glutaric acid, adipic acid, ethylsuccinic acid, methylglutaric acid and mixtures thereof wherein: A is a C4 to C6 linear or branched aliphatic chain, and R is an alkyl, a cycloalkyl or an aryl. The plasticizing agent according to the present invention has a good performance for different types of formulations (foam, film and paste). Said plasticizer gels rapidly, has a very low viscosity, and ages very well. Efficient debubblizing is one of the key properties thereof. The foams prepared with said plasticizer have very low densities, a high expansion rate, and excellent qualities.
