HPMC, or hydroxypropyl methylcellulose, is a chemical compound commonly used in a variety of industries, including pharmaceuticals, cosmetics, and construction. Here are some frequently asked questions about HPMC: What is HPMC? HPMC is a synthetic polymer made from cellulose, a natural substance found in plants. It is created by chemically modifying cellulose with methyl and […]

SLEOCHEM cellulose ethers are a popular group of chemical additives used in the construction industry for various purposes. These additives are derived from natural cellulose and are modified to enhance their properties, making them ideal for use in a wide range of construction applications. Some of the advantages of using SLEOCHEM cellulose ethers in building […]

HPMC in construction mortar plastering mortar High water retention can fully hydrate the cement, significantly increase the bonding strength, and at the same time can appropriately increase the tensile strength and shear strength, greatly improve the construction effect and increase the work efficiency. HPMC in water-resistant putty powder In the putty powder, the cellulose ether […]

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 […]
