Histrorically, the measure of thermal performance on given PVC compositions has been approximated by the metal content of the chosen heat stabilizer. However, advances in tin and ligand chemistry necessitate the evaluation of thermal stabilizers on criteria other than metal content. Many factors including the nature of the metallic species and relative activity of the organic ligands must be considered. A discussion will be given on the facets of heat stabilizer compositions and their effects upon PVC formulations and processing. Performance criteria for organotin stabilizers. The take-home point will be that tin content alone, in most formulations, is not the most important determinant in PVC heat stabilizer effectiveness.
