Abstract: Methods of re-dispersing and de-agglomerating dewatered, partially dried and dried compositions of microfibrillated cellulose and compositions of microfibrillated cellulose and inorganic particulate material, into liquid compositions comprising same, by applying ultrasonic energy to such liquid compositions of dewatered, partially dried and dried compositions of microfibrillated cellulose, or compositions of microfibrillated cellulose and inorganic particulate material. Methods for preparing an aqueous suspension comprising microfibrillated cellulose and, optionally, inorganic particulate material, with enhanced viscosity and tensile strength properties, suitable for use in methods of making paper or coating paper, and to filled and coated papers made from such aqueous suspensions.

Abstract: A process for modifying the paper burst strength enhancing attributes of microfibrillated cellulose may include subjecting an aqueous suspension including microfibrillated cellulose, and optionally inorganic particulate material, to high shear, wherein the high shear is generated, at least in part, by a moving shearing element, to modify the paper burst strength enhancing attributes of the microfibrillated cellulose. An aqueous suspension may include microfibrillated cellulose, and optionally inorganic particulate material, obtainable by the process. A papermaking composition and/or a paper product may be obtained from the process.
