Omya developed the Smartfill technology platform to improve the performance of Calcium Carbonate in polyesters and especially in Polylactic Acid. In Polyolefins and Polystyrene, the use of Calcium Carbonate is well known and addition rates of up to 40% are quite common. However, in the case of PLA, using conventional Calcium Carbonate products has led to poor product performance as a result of hydrolysis during processing. For this reason, high loadings of Calcium Carbonate in PLA or PLA rich compounds have not been feasible or beneficial. With the development of Omya Smartfill® technology the situation has changed. Products like Omya Smartfill® developed specifically for PLA applications demonstrate almost no hydrolysis when processed at high loading. At the same time, the addition of Omya Smartfill® improves product stiffness, impact resistance, elongation, heat transfer, and it contributes to an overall reduction in formulation cost. |
