HPMC Chemical for Detergent ThickenerMarch 4th 2024
Construction grade HPMC (hydroxypropyl methylcellulose) is a non-ionic cellulose ether that is commonly used as a thickening, water-retention, and adhesion-enhancing agent in various construction materials, including tile adhesives, gypsum, wall putty, and mortar. It is a white or off-white odorless powder that is soluble in water and polar solvents.
HPMC is produced by etherifying cellulose, a natural polymer, with propylene oxide and methyl chloride. The degree of etherification determines the properties of the HPMC, such as its viscosity, water retention, and adhesion. Construction grade HPMC typically has a medium viscosity and high water retention capacity.
HPMC is used in construction because it can improve the workability, adhesion, and water retention of various materials. It can also help to prevent shrinkage and cracking, and it can extend the open time of adhesives and plasters. In addition, HPMC can improve the pumpability of concrete and mortar.
Here are some of the specific benefits of using construction grade HPMC:
Overall, construction grade HPMC is a versatile and valuable additive that can improve the performance of a variety of construction materials.
