1、The HPMC is widely used in building material, coating, synthetic resin, ceramics, medicine, food, textile, agriculture, cosmetics, and tobacco industry and so on. The methylcellulose is take the natural high polymer material cellulose as a raw material, but makes the non-ionic cellulose ether after a series of chemistries processing. The PHMC is tasteless, non-flavor non-toxic white powder, can dissolve to the cold water, forms transparently thick solution. Have the characters of thicker the solution, agglutination, disperser, emulsification, form film, aerosol, adsorption, gelatin gelling, surface activity, maintenance moisture content and protective colloid and so on. 2.
