JOYFORCE Polyvinyl Alcohol Water-soluble polymers are mainly used in surface sizing agents, pigment binders and paper additives in the paper industry. In the past, starch pigments were used for surface sizing agents, and casein was mainly used for binders. Polyvinyl alcohol has better adhesion to cellulose than casein, strong film-forming properties, and good film-forming strength. Therefore, the demand for polyvinyl alcohol as a paper processing agent is rapidly expanding. With the advancement of paper, large-scale and high-speed paper making equipment, and rationalization of packaging methods, there is an increasing demand for polyvinyl alcohol.
