Cement is a fundamental building material used in construction projects around the world. It is made up of several components, including water, aggregates, and Portland cement. However, these components alone may not be enough to achieve the desired properties, such as workability, strength, and durability, that are necessary for construction applications. Therefore, additives are commonly […]

Hydroxypropyl methyl cellulose is a kind of nonionic cellulose ether, which is made from natural plant macromolecular cellulose through a series of chemical processing. It is an odorless, tasteless, non-toxic white powder. Soluble in cold water and organic mixtures. In the production process of hand sanitizer, adding an appropriate amount of hydroxypropyl methyl cellulose can […]

Methyl cellulose MC and hydroxypropyl methyl cellulose (HPMC) have stable chemical properties. Mildew resistance and water retention are not affected by changes in pH. Viscosity can be used between 50,000 and 200,000, but in production, higher viscosity is better. Viscosity is inversely proportional to bond strength. The higher the viscosity, the lower the strength. Regarding […]

MC is a kind of methyl cellulose, which is obtained by treating refined cotton with alkali and using MC as etherification agent through a series of reactions to generate cellulose ether.The degree of substitution is generally 1.6 to 2.0, depending on the solubility. HPMC is hydroxypropyl methyl cellulose, is refined cotton alkalization, with acetal oxide […]

Cellulose ether HPMC(hydroxypropyl methyl cellulose) and MHEC(Methyl hydroxy ethyl cellulose) in dry mortar:  The water retention of cellulose ether(HPMC,MHEC) comes from its own solubility and dehydration. Although the molecular chain of cellulose contains a lot of hydroxyl groups with strong hydration properties, it is not soluble in water, This is because the cellulose structure has a […]

HPMC (Hydroxypropyl Methyl Cellulose) and HEMC (Hydroxyethyl Methyl Cellulose) are two types of cellulose ethers that are commonly used in various industries including pharmaceuticals, food, construction, and personal care. The main difference between HPMC and HEMC is the chemical structure of the cellulose molecule. HEMC has a hydroxyethyl group attached to the cellulose backbone, while […]

Hydroxypropyl Methyl Cellulose (HPMC) is indeed a high-viscosity cellulose ether. It’s commonly used in various industries including construction, pharmaceuticals, and cosmetics. Here’s a breakdown of its properties and uses: Properties: Viscosity: HPMC can have varying viscosities depending on its molecular weight and degree of substitution. Solubility: It’s soluble in water and some organic solvents. Film Forming: It can […]

Hydroxypropyl methyl cellulose ether, a water-soluble polymer, is widely used in the field of building materials. Its application in cement mortar has undoubtedly injected new vitality into this ancient material. HPMC has excellent adhesion, fluidity and crack resistance, making it an ideal choice for improving the performance of cement mortars. 1. Improve bonding force and […]

Hydroxypropyl methyl cellulose is a building material additive. It is a kind of odorless white powder. The raw material of hydroxypropyl methyl cellulose is mainly natural polymer material cellulose. The non-ionic cellulose ether produced by oftencomplicated chemical processing has more Features such as thickening, water retention, dispersion, emulsification, film formation,adhesion. HPMC hydroxypropyl methyl cellulose used for […]
