Ultra-fine Precipitated Calcium Carbonate and its Function as Rubber Additive Shoichi TSUTSUI SHIRAISHI CENTRAL LABORATORIES CO., LTD Nippon Gomu Kyokaishi,(2005),78(6),218-223 General Review in Japanese Abstract 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 Compound as 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. Keywords: Ultra-faine Calcium carbonate, Nano-particle, Additive, Heat build-up, BIT
