SiO2 Reinforcement of Mechanical Properties for Ebonite from Natural Rubber

Nattawat Winya and Narupon Pittayaprasertkul
Abstract—To reinforce the mechanical properties of the rubber compounds, the silica was added. In this work, we measured the tensile strength and hardness of the compounds, in which the amounts of sulphur and silica were varied from 45 to 60 phr and 5 to15 phr, respectively. The experimental results showed that the addition of 10 phr silica 10 provides the maximum tensile strength and hardness. However for the amount of silica higher than 10 phr, the tensile strength tended to decrease. We also observe that the amount of sulphur 60 phr with 10 phr silica gives the maximum hardness (73 shore D).

Index Terms—Natural rubber, silica, ebonite, hard rubber, sulphur vulcanization.
