Step 1: Select the right grade of HPMC for your formulation. The market is flooded with different types, and they all have different characteristics. The viscosity (measured in cps), particle size, and whether or not a preservative is required will determine what HPMC you should choose. It is important to use surface-treated HPMC when making […]

The HPMC chemical structure affects its performance in various ways. The degree of substitution affects the solubility, gelation temperature, and viscosity of HPMC. A higher DS results in a more hydrophilic polymer, which increases its solubility in water. It also reduces the gelation temperature of HPMC, making it easier to form gels. The molecular weight […]

HPMC has a wide range of applications in various industries, including pharmaceuticals, food, cosmetics, detergent and construction. Its applications are based on its unique properties, which are a result of its chemical structure. In the pharmaceutical industry, HPMC is used as a binder, disintegrant, and controlled-release agent in tablet formulations. Its high viscosity and good […]

HPMC is a semi-synthetic polymer derived from cellulose. It is made by treating cellulose with an alkali solution to form alkali cellulose. The alkali cellulose is then reacted with methyl chloride and propylene oxide to form HPMC. The HPMC chemical structure is complex, but it can be simplified as a cellulose backbone with methyl and […]

Use basic properties to qualify its quality 1. Appearance: The appearance should be white free-flowing uniform powder without irritating smell. Possible quality manifestations: abnormal color; impurity; particularly coarse particles; abnormal smell. 2. Dissolution method: Take a small amount of redispersible polymer powder and put it into 5 times the water, stir first and then wait […]

The setting time of concrete is mainly related to the setting time of cement, and the effect of aggregate is not large. Therefore, the setting time of mortar can be used to study the effect of Hydroxypropyl methylcellulose HPMC on the setting time of underwater non-dispersed concrete mixtures. Since the setting time of mortar is […]

One of the biggest differences between dry mix mortar and traditional mortar is the modification of dry mix mortar with a small amount of chemical additives. Adding one additive to dry mortar is called primary modification, and adding two or more additives is secondary modification. The quality of dry powder mortar depends on the correct […]

HPMC solubility in water has two types: surface-treated HPMC and non-surfaced treated HPMC. hpmc-solubility-in-water 3.1 surface treated HPMC solubility in cold water When adding surface-treated HPMC into the water, HPMC will disperse into the cold water. But don’t have any viscosity. It is just dispersed. stir it and wait around 2 minutes, the solution becomes […]
