PERFORMANCE OF DI-N-HEXYL PHTHALATE IN FLEXIBLE VINYL FORMULATIONS

摘要

Low molecular weight esters have been available to the PVC compounder for many years. They have found a significant niche in the performance vs. permanence compromise as a compound ingredient that provides manufacturing efficiency or some special property with adequate permanence far many vinyl applications. In many respects, low molecular weight esters are the processing aids of the plasticizer family. This group of plasticizer may be said to include C_4 to C_7 dialkyl phthalates, the benzyl phthalates and the benzoic acid esters. This paper will introduce and compare di-normal hexyl phthalate (DNHP) to other phthalates against which it will directly compete.
