In the construction industry, cement-based and gypsum-based products are common building materials. Cement and gypsum, as the main components, play crucial roles in enhancing product strength, durability, and water resistance. However, with technological advancements and the diversification of user demands, improving the performance of these traditional building materials has become a key area of research. […]

Following are some of the key factors that may have an impact on HPMC viscosity: 1. Molecular weight: The higher the molecular weight, the higher the viscosity. 2. Degree of substitution: The number and type of substituent groups determine the polymer’s solubility and viscosity. 3. Concentration in solution: The higher the concentration, the thicker the solution. 4. Temperature: The viscosity […]

Chemical Structure: HPMC is made by replacing cellulose’s hydrogen atoms with hydroxypropyl and methyl groups, leading to a non-ionic, stable compound. Water Solubility: It dissolves easily in water, making it ideal for applications requiring stable dispersions or consistent texture. Thermal Gelation: HPMC’s gelation upon heating offers valuable control in pharmaceutical and construction uses. pH Stability: […]

Thermal stability of HPMC and MHEC is affected by their gel temperature. In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that […]

Used as thickener, dispersant, water retention agent and air-entraining agent etc. Mainly used in cement and gypsum based dry mix mortar to increase bond strength, workability, and water retention. Reduce water loss on concrete surface, preventing cracks and increase scrape area. It is widely used in wall plaster and tile adhesive products In paints, as […]

Water Retention: One of the primary functions of HPMC in mortar is to enhance water retention. By forming a thin film around cement particles, HPMC effectively reduces water evaporation during the curing process, ensuring prolonged hydration and optimal development of mortar strength. This property is particularly advantageous in hot and dry climates or during prolonged […]

HPMC belongs to the family of cellulose ethers, derived from natural cellulose through a series of chemical modifications. Its chemical structure comprises repeating units of glucose molecules substituted with methyl and hydroxypropyl groups. The degree of substitution (DS) and the molar substitution (MS) determine the properties of HPMC, including viscosity, solubility, and thermal stability. The […]

Efficient Construction Processes: The improved workability and extended open time provided by HPMC contribute to more efficient construction processes. This is particularly beneficial in large-scale projects where precise application and flexibility during construction are essential. Sustainability and Environmental Considerations: Derived from renewable resources, HPMC aligns with the growing emphasis on sustainable construction practices. Its biodegradability […]

Enhanced Workability and Water Retention: HPMC’s exceptional water retention capacity is a game-changer in construction materials. By forming a film around cement particles, it extends workability, allowing for more precise application and finishing in applications such as mortar and plaster. Improved Adhesion and Cohesion: The role of HPMC in promoting adhesion cannot be overstated. Its […]
