HY-Z-90

HY-Z-90

Product Description

HY-Z-90 is a kind of fine grinding process calcined kaolin with chemical composition of anhydrous aluminum silicate. In virtue of its good properties of high brightness, ultra-fine particle size and reasonable particle size distribution, it can significantly enhance paper brightness, smoothness, glossiness, opacity and improve the ink absorption ability and printing adaptability. Besides, it has high viscosity concentration and good mechanical dispersion, Widely used in the papermaking industry.
