Σκόνη HPMC
Σκόνη HPMC is refined from cotton after alkalization. It uses propylene oxide and methyl chloride as etherification agents to produce non-ionic cellulose mixed ether after a series of reactions. Milestone Industrial Co. Ltd. has 20 years of experience in the production of HPMC powder, with professional laboratories and workshops, and efficient after-sales service guarantee. It can customize Σκόνη HPMC with different viscosities according to customer needs.

Σκόνη HPMC product features:
1. Σκόνη HPMC 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 Σκόνη HPMC 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 Σκόνη HPMC is lower than that of methyl cellulose.
3. The water retention capacity of Σκόνη HPMC depends on its added amount, viscosity, etc.; the water retention rate is higher than that of methyl cellulose.
4. Σκόνη HPMC 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. Σκόνη HPMC is stable to ordinary salt, but when the concentration of the salt solution is high, the viscosity of the Σκόνη HPMC solution tends to increase.
5. Σκόνη HPMC 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. Σκόνη HPMC 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 Σκόνη HPMC and mortar structure is higher than that of methyl cellulose.
Σκόνη HPMC produced by MST is used in the fields of water-resistant putty powder, putty paste, tempered putty, paint glue and thermal insulation mortar.
