Hydroxypropyl Methyl Cellulose Ether HPMC
Description of Hydroxypropyl Methyl Cellulose:
Hydroxypropyl Methyl Cellulose is an Industrial Grade HPMC, which is mainly used as a dispersant in the production of PVC. It is the main auxiliary for the preparation of PVC by suspension polymerization. In addition, it is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film forming agent, etc. in the production of other petrochemical, paint, building materials, paint remover, agricultural chemicals, ink, textile printing and dyeing, ceramics, paper making, cosmetics and other products. The application in the synthesis of Resin can make the obtained products have the characteristics of regular particles, loose, appropriate specific gravity, and excellent processing performance, thus basically replacing gelatin and Polyvinyl Alcohol as dispersants. In addition, in the construction process of the building industry, it is mainly used in the mechanized construction such as wall laying, plastering and caulking; Especially in decorative construction, it can be used to paste ceramic tile, marble and plastic decoration with high adhesive strength and can also reduce the amount of cement. Used as a thickener in the coating industry, it can make the layer bright and fine, without removing powder, and improve leveling performance.
