The present invention relates to a general formula (I) derived from a vinyl chloride resin and a diacid selected from succinic acid, glutaric acid, adipic acid, ethyl succinic acid, methyl glutaric acid and mixtures thereof. [Chemical 1] (Where: A is a C 4 -C 6 linear or branched aliphatic chain, R is alkyl, cycloalkyl or aryl) And a plasticizer comprising at least one diester having: The plasticizers according to the invention have good performance for different types of formulations (foams, films and pastes). The plasticizer gels rapidly, has a very low viscosity and ages very well. Efficient defoaming is one of its important characteristics. Foams produced using the plasticizer have very low density, high expansion rate, and excellent quality. |
