This article provides an in-depth overview of HPMC manufacturing in China, highlighting the major companies, their technologies, product portfolios, and the role they play in the global cellulose ether market.

Overview of the HPMC Industry in China

Development of Cellulose Ether Manufacturing

Cellulose ether production began developing in China in the late twentieth century. Initially, the industry relied heavily on imported technology and products from European and American companies. Over time, domestic manufacturers invested heavily in research and development, enabling them to develop their own production processes and expand their manufacturing capacity.

Today, China is one of the world’s leading producers of HPMC and other cellulose ethers such as:

• Hydroxyethyl Cellulose (HEC)
• Hydroxyethyl Methyl Cellulose (HEMC / MHEC)
• Carboxymethyl Cellulose (CMC)
• Methyl Cellulose (MC)

Chinese manufacturers supply a large portion of the global demand for construction-grade HPMC used in tile adhesives, dry-mix mortar, wall putty, gypsum products, and self-leveling compounds.

Applications of HPMC

HPMC has diverse industrial applications because of its unique chemical properties. The most common applications include:

Construction Materials

The construction industry represents the largest market for HPMC. In dry-mix mortar formulations, HPMC acts as a water retention agent and thickener, improving workability and adhesion. It is widely used in:

• Tile adhesives
• Wall putty
• Cement renders
• Self-leveling compounds
• Exterior insulation systems

HPMC helps prevent water loss during cement hydration, ensuring stronger bonding and improved durability.

Pharmaceutical Industry

In pharmaceutical formulations, HPMC is used as a binder, film-forming agent, and controlled-release matrix. It plays an important role in tablet coatings and capsule production.

Food Industry

Food-grade HPMC is used as a stabilizer, emulsifier, and thickening agent in various processed foods. It helps improve texture, moisture retention, and shelf life.

Personal Care and Cosmetics

HPMC is widely used in cosmetics and personal care products such as shampoos, lotions, and creams due to its thickening and stabilizing properties.
