Comparison of properties of cellulose ether MST® HPmc
cellulose powder and MC:
1) Hpmc cellulose powder Manufacturers is easily soluble in cold water, and it will be difficult to dissolve in hot water. The gelation temperature of Hpmc cellulose powder Manufacturers in hot water is significantly higher than that of MC. The dissolution of Hpmc cellulose powder Manufacturers in cold water is much better than that of MC.
2) The viscosity of Hpmc cellulose powder Manufacturers is related to its molecular weight, and the higher the molecular weight, the higher the viscosity. Temperature will also affect the viscosity of Hpmc cellulose powder Manufacturers, as the temperature increases, the viscosity decreases. However, the effect of temperature on the viscosity of HPMC is lower than that of MC.
3) The water retention of Hpmc cellulose powder Manufacturers depends on its added amount, viscosity, etc. In application, the water retention rate of HPMC is higher than MC at the same amount.
The water retention of MC depends on its addition, viscosity, particle fineness and dissolution speed. Generally, if the addition amount is large, the fineness is small, and the viscosity is large, the water retention rate is high. Among cellulose ethers, MC and Hpmc cellulose powder Manufacturers have higher water retention rates.
4) Hpmc cellulose powder Manufacturers can be mixed with water-soluble polymer compounds to form a uniform and higher viscosity solution. The adhesion of Hpmc cellulose powder Manufacturers to mortar construction is higher than that of MC.
5) Hpmc cellulose powder Manufacturers has better enzyme resistance than MC, but its solution enzymatic degradation possibility is lower than MC.
In short: MST® Hpmc cellulose powder Manufacturers has better performance and is more widely used in construction industry.
