Abstract
The low temperature and isothermal dynamic mechanical proper ties for different plasticizers like aromatic oil, paraffinic oil, and di-octyl phthalate (DOP) in epoxidized natural rubber (ENR) vulcanizates were stud ied. 10, 20, and 40 phr of aromatic oil were used for studying the effect of plasti cizer concentration on the above mentioned properties. Though the low temper ature flexibility was equally improved by all the three types of plasticizers, the addition of paraffinic oil was found to be more effective in ENR. Increasing con centration of aromatic oil in ENR showed that the Tg values are decreased and the low temperature flexibility increased.
