Patent number: 11970817Abstract: A method for preparing an aqueous suspension may include providing a fibrous substrate comprising cellulose having a Canadian Standard freeness equal to or less than 450 cm3, and microfibrillating the fibrous substrate in an aqueous environment by grinding in the presence of a grinding medium consisting essentially of mullite. The grinding may be carried out in the absence of grindable inorganic particulate material. The grinding medium may be present in an amount of at least about 10% by volume of the aqueous environment. The microfibrillated cellulose may have a fibre steepness of from about 20 to about 50.Type: GrantFiled: May 27, 2022Date of Patent: April 30, 2024Assignee: FIBERLEAN TECHNOLOGIES LIMITEDInventors: John Claude Husband, Per Svending, David Robert Skuse, Tafadzwa Motsi, Mikko Likitalo, Alan Coles
