1. OBJECTIVE To determine the crosslink parameters of a vulcanised natural rubber 2. INTRODUCTION Natural rubber is an elastic substance derived from the latex sap of trees, especially trees belonging to the Hevea and Ficus genera. Natural rubber is either an elastomer or an elastic hydrocarbon polymer. Synthetic rubber is a man-made rubber produced at manufacturing plants by synthesizing it with petroleum and other minerals. Cross-like polymers are a type of polymer whose molecular chai...
