The bentonite products Sinomont and Sinosorb are used for retention, elimination of sticky residues or water treatment in the paper production supporting the optimum flocculation behavior and high adsorption capacity of disruptive substances during the recycling of waste paper and helping to avoid problems with resins or sticky residues. Through the large surface area and cation exchange capability the products are often used in the microflotation stage of the de-inking process. The products contribute to achieving a high level of process reliability, effectively reduce paper machine downtime and thus have a direct positive effect on cost reduction.
