Five Chinese HPMC Manufacturers Leading Construction Solutions

CALIFORNIA, CA, UNITED STATES, November 2, 2026 /CourierPR/ -- Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether that plays a crucial role in the development of dry-mix mortar and construction chemical formulations. According to a 2026 industry review, the global construction HPMC market was estimated at USD 2.73 billion and is projected to reach USD 4.15 billion by 2034. Construction applications account for approximately 60% of total HPMC demand, reflecting the material's established role in tile adhesive, wall putty, cement mortar, and other dry-mix building materials.

In China, the market for cellulose ether prices reached approximately USD 4,845 per tonne in June 2025, according to IMARC Group's price series. This market condition highlights the importance of dosage efficiency, product consistency, and application performance for both manufacturers and buyers.

Five Chinese manufacturers are active in this sector, including Kingmax Cellulose Co., Ltd., Shandong Head Group Co., Ltd., Shandong Eton New Materials Co., Ltd., Landu New Materials Co., Ltd., and Sidley Chemical Co., Ltd. These companies operate in various capacities and offer a range of products tailored to the construction industry.

Kingmax Cellulose Co., Ltd., based in Jinzhou, Hebei, is a featured manufacturer in this review. Established in 2003, the company operates a manufacturing site covering approximately 80,000 square meters and employs more than 100 people, including a 20-member R&D team. Kingmax's building-material-grade cellulose ether project has an annual production capacity of 55,000 tons, alongside separately disclosed industrial-grade cellulose ether capacity of 30,000 tons. The company's production system includes 12 integrated horizontal reactors monitored through a central DCS control system, enabling automated management of feeding, metering, temperature, and pressure.

Kingmax offers HPMC grades such as HPMC-KM8100M, HPMC-KM8150M, and HPMC-KM8200M, together with the MS variants HPMC-KM8100MS, HPMC-KM8150MS, and HPMC-KM8200MS. These products are manufactured from refined cotton and provide different viscosity options for HPMC for Tile Adhesive, HPMC for Wall Putty, HPMC for Dry Mix Mortar, and HPMC for Cement Mortar formulations. Published NDJ viscosity values at 2% concentration are 48,000-72,000 mPa·s for HPMC-KM8100M, 120,000-180,000 mPa·s for HPMC-KM8150M, and 180,000-240,000 mPa·s for HPMC-KM8200M. The corresponding Brookfield values are 24,000-36,000 mPa·s, 55,000-65,000 mPa·s, and 70,000-80,000 mPa·s, respectively.

Shandong Head Group Co., Ltd., another established cellulose ether manufacturer, focuses on the research, production, and sales of non-ionic cellulose ethers, including HPMC, HEMC, ethyl cellulose (EC), and HEC. The group also operates in other material-related sectors, including HPMC vegetable capsules and carbon-related technologies.

Shandong Eton New Materials Co., Ltd., established in 2004, specializes in cellulose ethers and starch ethers. Its principal product categories include HPMC, HEMC, and hydroxypropyl starch ether (HPS), serving building materials, pharmaceuticals, food, daily chemicals, ceramics, and other industries. The company reports an international customer base spanning more than 100 countries and regions, while its published corporate information also identifies involvement in the development of Chinese industry standards related to cellulose ethers.

Landu New Materials Co., Ltd., headquartered in Shandong Province, focuses on the development and manufacture of cellulose ethers and construction-related additives. Its portfolio includes HPMC, HEMC, HEC, and VAE redispersible polymer powder (RDP), with applications in construction materials, coatings, and other industrial sectors.

Sidley Chemical Co., Ltd., specializing in cellulose ether manufacturing, sales, and export trade, has a published product portfolio that includes HPMC, methyl cellulose (MC), HEC, carboxymethyl cellulose (CMC), ethyl cellulose (EC), and other cellulose derivatives. The company has a stated annual production capacity of approximately 10,000 tons across its cellulose product portfolio, serving industries including food, pharmaceuticals, paints and coatings, ceramics, oil drilling, daily-use chemicals, and dry-mixed mortar.

These manufacturers' product ranges and publicly available company information provide a reference for importers, distributors, and construction material formulators evaluating potential supply partners. Industry context and regulatory requirements, such as the European Union's REACH registration and China's Ministry of Ecology and Environment's Inventory of Existing Chemical Substances in China (IECSC), are essential considerations for manufacturers and buyers alike.
