ABSTRACT:
There is disclosed the use of esters especially methyl esters of rosin acids as total or partial replacements for oil in rubber formulations. Vulcanizate properties, low temperature performance, and processibility are comparable when using either the rosin ester or an aromatic oil, however, the rosin ester extended rubber demonstrates improved abrasion resistance and flex resistance.
