Reason: The water temperature fluctuated greatly during dissolution, resulting in uneven dissolution of HPMC. Insufficient stirring time or too short resting time, HPMC is not completely dissolved. HPMC batch differences or improper storage conditions affect viscosity stability. Solution: Maintain a constant water temperature during the dissolution process, stir and leave it for enough time (usually […]

HPMC is very sensitive to temperature and exhibits significant differences in dissolution characteristics at different temperatures. Therefore, it is necessary to control the water temperature to prevent sudden changes in viscosity or incomplete dissolution.HPMC usually disperses better in cold water, while it tends to swell or agglomerate in hot water. Solution: Avoid using high temperature […]

Water Retention: HPMC is highly effective in retaining water in construction materials, preventing the premature drying of mortars and improving their workability. This ensures that the materials remain workable for longer periods, allowing for better application. Improved Adhesion: HPMC improves the bonding strength of building materials such as tile adhesives, gypsum-based products and cement-based plasters. […]

HPMC is a cellulose derivative. It is widely used in the construction, daily chemical and pharmaceutical industries, which is generally safe for human use. Construction In construction, HPMC is used in products such as tile adhesives, wall putty and other mortars. In this context, the main exposure route for humans is through skin contact during handling or inhalation […]

In dry mix mortar, adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar. ● Water Retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have […]

In dry mix mortar, adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar. Generally, a small amount of HPMC can greatly increase the water retention rate of the mortar. When the content reaches a certain […]

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 […]

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 water retention […]

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 […]
