YPZ series of water-based colorants contain organic or inorganic pigment dispersed in the water by nonionic or anionic wetting & dispersing agents and are designed for the internal coloring of pulp fibers. YPZ series of water-based colorants cover a wide color range and show excellent tinting strength and strong retention performance due to good adsorbability on various paper fibers. The colorants are less affected by PH value and chemicals in the pulp during use, have no adverse effect on the original performance indexes of pulp and paper , have high weather resistance, light resistance and chemical resistance, and does not change color or migrate during drying.
Among YPZ series,purple YPZ801 and blue YPZ are substitutes for fluorescent brighteners widely used in papermaking industry and can also replace reddish blue and other dye colorants, mainly used for whitening and whitening of high-grade coated paper.
