The MST® China Chemical Hydroxypropyl Methyl Cellulose suppliers produced by Milestone Inudstrial Co. Ltd. is a non-ionic cellulose ether with a white powder appearance. As a water-soluble polymer, it has excellent surface activity and acts as a colloidal protective agent. Function, it can effectively prevent the aggregation of polymer particles; it has acid and alkali resistance and is relatively stable in acidic and alkaline solutions. It has the characteristics of high water retention, good dispersibility, fineness, workability, and convenient dissolution.
Acid and alkali resistance of MST® Chemical Hydroxypropyl Methyl Cellulose:
1) China Chemical Hydroxypropyl Methyl Cellulose suppliers is generally stable in acidic and alkaline solutions, and will not be affected in the range of pH 2~12;
2) China Chemical Hydroxypropyl Methyl Cellulose suppliers can withstand a certain amount of light acid, such as formic acid, acetic acid, citric acid, succinic acid, phosphoric acid, boric acid and other acidic solutions. HPMC is stable in it. However, the viscosity of China Chemical Hydroxypropyl Methyl Cellulose suppliers will decrease in concentrated acid.
3) China Chemical Hydroxypropyl Methyl Cellulose suppliers has stable performance in alkaline solutions such as caustic soda, caustic potassium and lime water, etc., and will not be affected; but after mixing, the viscosity of the solution can be slightly increased during the dissolution process, and it will be slower in the future. The phenomenon of decline.
