Influence of Plasticizers Basing on Renewable Sources on the Deformation and Fracture Behaviour of Elastomers

Abstract

This contribution is focused on the quasi-static and impact fracture behaviour of technical, filler-reinforced elastomer compounds containing plasticizers basing on renewable sources in various amounts. Beside the conventional plasticizer TDAE as benchmark, various plasticizer products like epoxidized rapeseed oil, rapeseed oil methyl or propyl ester, epoxidized canola oil or epoxidized ester of glycerol formal from canola oil were used. Main aims are to find products as replacement of traditional mineral oil-based plasticizers and to understand the interaction of polymer and plasticizer and the resulting properties, especially the deformation and fracture behaviour. It was shown that by using renewable plasticizers a comparable or better property level of technical rubber vulcanizates is possible.
