Abstract:
A precipitated carbonate polysaccharide structure which, when used as a filler, improves the structural strength of paper or board, or gypsum boards, plastics or gums, among others, as well as the stiffness level and optical properties (brightness and opacity) of the paper or board, together or separately with other fillers; carbonates, in particular. The invention further improves the setting of printing ink on the surface of the paper or board. The invention also includes the manufacturing method of the precipitated carbonate polysaccharide structure.
