For csm/smr 20 cv blend, the cure index shows a maximum at 20 pphr of smr 20 cv in the blend at lower vulcanization temperature, an observation which is attributed to the incompatibility between csm and smr 20 cv and the faster cure rates of the latter.

Up to 10% cash back vulcanization of natural rubber (nr) with conventional accelerated sulphur (cv) system leads to vulcanizate with polysulfidic linkages in the network. These polysulfidic linkages are less stable at elevated temperature due to reversion, which reduces the mechanical properties and increases the compression set.

Vulcanisation Is Measured By The Increase In The Torque Required To Maintain A Given Amplitude Of Oscillation At A Given Temperature.

Fourier transform infrared spectroscopy with attenuated total refletance analysis and gel content confired crosslinking occurred in the rubber blends in the presence of peroxide dtbpib percentage. Cure characteristics such as scorch time and cure time of the natural rubber compounds decrease with increasing recycled rubber powder loading but show slight increases in minimum torque. Studies including tensile properties, dynamic mechanical properties, thermogravimetric analysis (tga) and water absorptivity showed the changes in.
