HPMC v prahu product features:

1. HPMC v prahu is easily soluble in cold water, hot water will dissolve. Its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also much better than methyl cellulose.

2. The viscosity of HPMC v prahu is related to the molecular weight. When the molecular weight is large, the viscosity is high. Temperature will also affect its viscosity, as the temperature increases, the viscosity decreases. But the high viscosity of HPMC v prahu is lower than that of methyl cellulose.

3. The water retention capacity of HPMC v prahu depends on its added amount, viscosity, etc.; the water retention rate is higher than that of methyl cellulose.

4. HPMC v prahu is stable to acid and alkali, and its aqueous solution is stable in the range of pH = 2-12. Caustic soda and lime water have little effect on its performance, but alkali can accelerate its dissolution and slightly increase its viscosity. HPMC v prahu is stable to ordinary salt, but when the concentration of the salt solution is high, the viscosity of the HPMC v prahu solution tends to increase.

5. HPMC v prahu can be mixed with water-soluble polymer to form a uniform and high viscosity solution. Such as polyvinyl alcohol, lake water powder ether, vegetable glue, etc.

6. HPMC v prahu has better enzyme resistance than methyl cellulose, and the possibility of enzymatic degradation of its solution is lower than that of methyl cellulose.

7. The adhesion between HPMC v prahu and mortar structure is higher than that of methyl cellulose.

   

HPMC v prahu produced by MST is used in the fields of water-resistant putty powder, putty paste, tempered putty, paint glue and thermal insulation mortar.
