HPMC(Hydroxypropyl Methyl Cellulose) and HEMC(Hydroxyethyl Methyl Cellulose) have similar roles in building materials. They can function as a dispersant, water-retaining agent, thickener, and binder to increase cohesiveness, workability, reduce flocculation, improve viscosity and shrinkage. Their water retention property will help to reduce concrete surface water loss, increase strength, prevent cracks and weathering of water-soluble salts. They […]

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 kind of cellulose ether which could be used in many application, such as in construction industry, food industry, pharmacy industry, daily chemical industry, and plays very important roles in building material, such cement mortar, tile adhesive, gypsum-based plaster, detergent and so on, and it will be critical for you to know how […]

1. What’s the meaning of MSDS MSDS full name is material safety data sheet(MSDS), also called safety data sheet (SDS) and product safety data sheet (PSDS), it is a document that lists information relating to occupational safety and health for the use of HPMC, it cataloging information on chemicals, chemical compounds, and chemical mixtures. MSDS of our HPMC includes instructions for the […]

1 water retention Hydroxypropyl methylcellulose HPMC for construction avoids moisture infiltration into the wall. The proper amount of water stays in the mortar, so that the cement has a longer time for hydration. The water retention is proportional to the viscosity of the cellulose ether solution in the mortar. The higher the viscosity, the better […]

1.Water retention:  HPMC is mainly used as water retaining agent in dry-mixed mortar. It helps to retain moisture in the mortar, ensuring that the mortar has enough time to hydrate the cementing material after construction. By retaining water, HPMC is contribute to improve the construction performance of mortar and extend its working life. 2.Thickening and wet viscosity:  HPMC can thicken the […]

1.What is the gel temperature of HPMC related to? Normally, for putty powder, the viscosity of HPMC is enough at about 70,000 to 80,000. The main focus is on its water retention performance, while the thickening effect is relatively minor. For mortar, the requirements for HPMC are higher, and the viscosity needs to be around […]

Adhesives are widely used in various industries, from construction to automotive, for bonding different materials together. The viscosity of an adhesive plays a crucial role in its performance, as it determines its ability to flow and adhere to surfaces. To improve the viscosity of adhesives, many manufacturers turn to Hydroxypropyl Methylcellulose (HPMC), a versatile additive […]

In recent years, there has been a growing interest in the electrical properties of materials made from Hydroxypropyl Methylcellulose (HPMC). HPMC is a versatile polymer that is widely used in various industries, including pharmaceuticals, cosmetics, and food. Its unique properties, such as biocompatibility, film-forming ability, and controlled release characteristics, make it an attractive choice for […]
