The author summarizes Synthetic Calcium Carbonate, especially Ultra-fine precipitated calcium carbonate (UF-PCC) and its function as Rubber Additive as follows: within Rubber formulation where Precipitated Silica was applied, the small amount of UF-PCC accelerated integration between Rubber and Precipitated Silica.
Also UF-PCC provided the better properties such as dispersion, tear strength and heat build-up to Rubber Compoundas well.
In the case of Carbon Black applied above formulation instead of Precipitated Silica, UF-PCC reduced BIT in mixing the rubber compound.
We also found that UF-PCC played a role of acid acceptor in the halogenated rubber utilizing UF-PCC and its alkaline property.
