The main use is as a dispersant in the production of polyvinyl chloride (PVC), being a major auxiliary in suspension polymerization for PVC production. Additionally, it is used as a thickener, stabilizer, emulsifier, plasticizer, water-retaining agent,leveling agent, and film-forming agent in other petroleum chemical,building materials, paint remover, agricultural chemicals, ink, textile printing and dyeing, ceramics, paper-making, cosmetics, and other products.In the application of synthetic resins, it can make the obtained products have regular particles, loose, suitable apparent specific gravity, and excellent processing performance. Furthermore, in the construction industry, it is mainly used in mechanized construction such as walling, plastering, and sealing; especially in decorative construction, it is used for pasting tiles,marble, and plastic decorations, with high adhesion strength and can also reduce the amount of cement used. Used as a thickener in the paint industry, it can make the coating bright and delicate, without powdering, and improve leveling performance. Used in plaster, bonding plaster, sealing plaster, and water-resistant putty, it can significantly improve water retention and bonding strength.
