US MASTERFILL has selected high quality ultrafine CaCO3 to product high concentration particles via twin screw pelletizers with a worlwide market share of approximately 70%, plays the dominant role.
As a largely inactive, low-cost filler, Calcium carbonate yields a reduction in the cost of the finished formulation without dramatic changes in properties. On account of its generally high chemical purity, good dispersion characteristics, and ability to be used at high filler loadings, US MASTERFILL offers a numbers of advantages to thermoplastics, such as slightly increased elastic modulus and impact strength, shrinkage reduction, good coloration, and excellent surface finish.
