Thermal stability of HPMC and MHEC is affected by their gel temperature. In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that HPMC. On the other hand, because there are more hydrophilic groups in the structure of MHEC, it has better hydrophilicity. The water retention rate of MHEC in mortar is a little higher than HPMC at the same dosage of products with the same viscosity.

6. A simple test method for the ash content of cellulose ether: weigh one to two grams of cellulose ether, ignite it with a lighter, weigh the ash residue left by the combustion of cellulose ether, and when the ash residue / cellulose ether is ≥ 5%, the quality of cellulose ether is basically unqualified. (there are sometimes errors in this method. First, the manufacturer compounded the products suitable for specific customers for customers before leaving the factory; second, the agents or manufacturers added flammable substances with low ash content when adulterating)
