BLK 6300 is a proprietary water-soluble polymers product used in the paper industry as a bulk & strength enhancer. BLK 6300 is a unique polymeric chemistry with its polymeric structure in built dispersing properties gives a partial restructuring of hydrogen bonds and forms in situ crosslinking creating stable micro voids stable to pressures and stress. BLK 6300 is an efficient strength enhancing agent for paper making. The main advantages of BLK 6300 in the production of paper making with normal thickness requires slightly lower amount of pulp contributing to saving cost per tons of pulp.

In addition to this bulking effect, BLK 6300 dramatically improve physical properties of paper like as strength & stiffness.
