Hydroxypropyl methylcellulose (HPMC) is an odorless, odorless, non-toxic milky white powder that can be dissolved in cold water to produce a transparent viscous aqueous solution. It has the characteristics of thickening, adhesion, dispersion, emulsion, demulsification, floating, adsorption, suspected glue, surface activity, moisturizing and hydrating, and maintaining colloidal solution.

Construction Grade Hpmc 

1. Lime mortar and cement mortar

High-moisture storage can make concrete fully solidify. The compressive strength of bonds continued to rise. In addition, the tensile and cutting compressive strength can be improved. Further improve the actual effect of project construction and enhance work efficiency.

2. Waterproof putty

The key function of cellulose ether in putty powder is to maintain moisture, adhesion and wetting, prevent cracks or open glue caused by too fast water shortage, improve the adhesion of putty powder, and reduce the suspension condition of the construction site. Make the project construction more complete and save human capital.

3. Interface agent

The key is as an emulsifier, which can increase the compressive strength and tensile strength, improve the surface coating, and improve the adhesion and adhesive compressive strength.

4. External wall insulation mortar

Cellulose ethers play a key role in bonding, improving compressive strength, making cement mortar easy to coat, and improving efficiency. In addition, it has the advantages of anti-vertical suspension work ability and strong water-locking work ability, which can increase cement mortar. Improve the anti-collapse and cohesion performance of the cement mortar, improve the process performance, and increase the adhesive compressive strength.

5. Tile glue

The high-grade water features do not need to pre-soak or wet the ceramic floor tiles and roadbeds, which can significantly improve the adhesive compressive strength. The mortar can have a long construction period, beautiful, well-proportioned, convenient construction, and strong ground slip resistance.

6. Grout Grout

The addition of cellulose ether has excellent edge adhesion, low shrinkage rate and high wear resistance. The basic raw materials will not be damaged by mechanical equipment and prevent the adverse effects of flooding on all buildings.

7. Self-plain materials

The stable viscosity of the cellulose ether ensures the excellent circulation of the cellulose ether and the self-leveling ability of the cement, controls the water retention rate, makes the cellulose ether coagulate rapidly, and reduces cracks and shrinkage.

Different Grades Of HPMC

Hydroxypropyl methylcellulose (HPMC) is available in different grades with specific characteristics and applications. Here are the different grades of HPMC in the context of construction, pharmaceuticals, food, and detergent industries:

Construction HPMC:

Construction hydrocel HPMC is primarily used in cement-based products, such as dry mixed mortars, tile adhesives, gypsum renders, and self-leveling compounds.
Construction Grade HPMC Viscosity (NDJ, mPa.s, 2%) Viscosity(Brookfield,mPa.s,2%)
HPMC MP400 320&#;480 320&#;480
HPMC MP60M &#; &#;
HPMC MP100M &#; &#;
HPMC MP150M &#; &#;
HPMC MP200M &#; &#;
Some key features of construction grade HPMC include:

· Improved workability: HPMC enhances the workability of cementitious materials, allowing for easier mixing, spreading, and application.

· Water retention: It helps in retaining water in the formulation, preventing rapid drying and ensuring proper hydration of cement.

· Increased adhesion: HPMC enhances the adhesion of cement-based materials to substrates, improving bonding strength.

·Sag resistance: It reduces sagging or slumping of vertical or overhead applications, maintaining the desired shape and preventing material wastage.

·Crack resistance: HPMC improves the flexibility and cohesion of cementitious materials, reducing the risk of cracking and enhancing durability.

HPMC in Pharmaceutical

Pharmaceutical-grade HPMC is widely used in the pharmaceutical industry for various applications, including controlled drug release systems, film coating, and mucoadhesive formulations.

Some key characteristics of pharmaceutical-grade HPMC include:

Controlled drug release: HPMC acts as a matrix former, enabling the controlled and sustained release of drugs from oral solid dosage forms.

Film-forming properties: It forms a smooth and protective film when applied to tablets or capsules, improving stability, appearance, and swallowability.

Mucoadhesive properties: HPMC enhances the contact time of drugs with mucosal surfaces, facilitating absorption and improving therapeutic efficacy.
Hydroxypropyl Methyl Cellulose In Food

Food grade HPMC is used in the food industry as a thickener, stabilizer, and emulsifier. It offers several advantages.

Some key characteristics of food-grade HPMC include:

· Thickening and stabilization: HPMC imparts viscosity, texture, and stability to food products such as sauces, dressings, and dairy items.

· Fat replacement: It can serve as a fat replacer, providing a desirable mouthfeel and texture in low-fat food formulations.

· Water retention: HPMC helps retain moisture in food products, maintaining freshness, juiciness, and preventing water loss.

· Film-forming properties: It forms a protective film on food surfaces, extending shelf life and enhancing appearance.
HPMC For Detergent

Detergent grade HPMC is specifically designed for use in laundry and cleaning products.
