HPMC Manufacturer

What is HPMC

Hydroxypropyl methyl cellulose (HPMC) is a commonly used additive in the construction industry. It is a non-ionic cellulose ether derived from natural cellulose and is available in the form of a white powder. HPMC offers several benefits in construction applications due to its unique properties. 

Here are some key uses of HPMC in construction:

Tile Adhesives: HPMC is added to tile adhesives to improve their workability, adhesion, and water retention properties. It helps to enhance the open time of the adhesive, allowing for easier tile positioning and adjustment.

Cement-Based Renders and Plasters: HPMC is used in cement-based renders and plasters to improve their workability, water retention, and sag resistance. It enhances the cohesion and consistency of the mixture, making it easier to apply and reducing the risk of cracks.

Self-Leveling Compounds: HPMC is incorporated into self-leveling compounds to improve their flow and leveling properties. It helps to achieve a smooth and even surface, especially for large areas, while minimizing shrinkage and improving the overall performance of the compound.

Exterior Insulation Finishing Systems (EIFS): HPMC is used in EIFS to enhance the adhesion, workability, and crack resistance of the coatings. It improves the durability and weather resistance of the system while maintaining its flexibility.

Gypsum-Based Products: HPMC is added to gypsum-based products such as joint compounds and gypsum plasters to improve their workability, adhesion, and crack resistance. It helps to achieve a smooth finish and reduces the risk of shrinkage cracks.

Mortars and Grouts: HPMC is used in cementitious mortars and grouts to improve their workability, water retention, and adhesion properties. It enhances the ease of application, reduces water loss, and improves the bond strength between the mortar or grout and the substrate.

Thermal Insulation Systems: HPMC is utilized in thermal insulation systems to enhance the adhesion and workability of the adhesive or mortar used for attaching insulation boards. It improves the performance and longevity of the insulation system.

Crack Fillers and Repair Mortars: HPMC is added to crack fillers and repair mortars to improve their workability, adhesion, and durability. It helps to fill and repair cracks effectively while enhancing the overall performance of the repair material.

Water-Based Paints and Coatings: HPMC is used in water-based paints and coatings to improve their rheological properties, adhesion, and sag resistance. It helps to achieve better film formation, leveling, and brushability.

Water Retention: HPMC acts as a water retention agent, allowing construction materials to retain water for a longer period. This property is beneficial in improving workability, reducing the risk of premature drying, and enhancing the curing process of various construction formulations.

HPMC is a versatile additive in the construction industry, offering benefits such as improved workability, adhesion, water retention, and crack resistance. Its usage contributes to the production of high-quality construction materials with enhanced performance and durability.

Construction grade HPMC properties:

1. Thickening: Cellulose can thicken to suspend, keep the solution uniform and consistent, and resist sagging.

2. Water retention: Make the putty powder dry slowly, and assist the reaction of lime calcium under the action of water.

3. Easy Construction: HPMC Cellulose has a lubricating effect, which can make the putty powder have good workability.

4. Resistant to hydrolysis and UV light: HPMC powder is suitable for use in high humidity and damp environments, which can also improve the durability of construction materials.

5. Non-ionic polymer:  Hydroxypropyl methyl cellulose does not react with other materials and can be used with a variety of additives.

Note: HPMC does not participate in any chemical reaction and only plays an auxiliary role.
