Applications
In the polymerization of synthetic resins, HPMC serves multiple roles. It acts as a dispersant and suspending agent for the polymerization of vinyl chloride and its copolymers. For the copolymerization of dichloroethylene and vinyl acetate, it functions as an emulsifier, while it stabilizes the suspension in the copolymerization of vinyl acetate and vinyl chloride. Additionally, HPMC is a stabilizer for the graft copolymerization of butadiene, acrylonitrile, and styrene.
In the pharmaceutical and food industries, HPMC is utilized as an additive for its thickening, solidifying, film-forming, dispersing, and stabilizing properties. It also provides moisture retention and mold prevention. In the coating industry, HPMC is used as an emulsifier, thickener, film-forming agent, and stabilizer. For photosensitive printing boards, its film-forming ability and photodegradability are crucial, enabling quick development with water. As a detergent additive, HPMC enhances the stain resistance of fabrics.
