In the case of commercial gaskets, T95% was always lower than those values obtained for plastisols prepared in the laboratory, particularly in the case of the asparagus jar and pesto sauce gaskets, where T95% values were clearly lower all the other mate- rials, either prepared or commercial. The explanation of this behaviour could be obtained when observing GC/MS results for plasticizers composition (Fig. 3). Thus, it was observed that any commercial gasket showed lower ESBO concentrations than those prepared in the laboratory and this was especially evident for pesto sauce gaskets which showed no ESBO at all in their composition, and consequently no stabilization from this compound should be expected. The case of asparagus gaskets is a bit more complicated, since some ESBO (around 6 ` 1 wt%) was determined in their composition. It was indicated that the increase caused by the ESBO stabilization is noticeable at concentrations higher than 1e2 wt%, and consequently these gaskets should show similar T95% values to those observed for the other commercial samples. However, the main difference in composition between asparagus and other gaskets is the presence of an important amount of ATBC (around 20 wt%) in their composition. This plas- ticizer has shown far lower values for T95% (around 145 C) than any other plasticizer detected in gaskets. Therefore, a double effect could be expected: on the one hand the stabilizing effect by ESBO
