Product Description

                                                                       Cellulose Ether
Construction grade cellulose ether is divided into HPMC and HEMC according to diferent substituent groups, The substitutegroups of HEMC are hydroxyethyl and methoxy, while the substitute groups of HPMc are hydroxypropyl and methoxyCompared with HPMC, HEMc has more hydrophilic groups, which means it has a relatively higher gel temperature, better wateiretention in hot environments, and better thermal stability, HPMC has better water retention and workability in wall putty, tileadhesive,and other products.

The performance of Cellulose Ether in dry mortar:
Excellent water retention can effectively prevent the mortar from losing water so quickly as to lose its operability, avoid rapidA.surface drying and cracking, and make the mortar have a longer openingtime and adjustment time;
B. The thickening effect of Cellulose Ether can control the mortar to achieve the best consistency, improve the cohesion ofthemortar, achieve the anti-sagging effect, improve operability, and greatly improve construction efficiency.C. it can improve the bonding strength of the mortar, and it can ensure sufficient moisture and time to fuly hydrate the cementthereby ensuring that the mortar has better bonding performance and strength even in a high temperature environment.


Surface-treated products are specially developed to avoid clumping in wet mixing applications. When preparing a solution witha surface-treated product, pour the product directly into cold water. The cellulose ether will quickly disperse into the water andslowly form a viscous solution within a certain period. The delaved dissolution time for surface-treated products (based on pH=7is usually around 5 minutes. However, if the pH value of the solution increases, the delayed dissolution time will be shortenedthe delaved dissolution time can be adiusted according to customer reauirements, Some surace-treated products are indicatecby the suffix'S" in the product grade,such as MP150000S
