HPMC Manufacturing Process

The production of Hydroxypropyl Methyl Cellulose (HPMC) begins with refined cotton as the raw material. The fibers undergo alkalization with sodium hydroxide, followed by etherification using chloromethane and propylene oxide to introduce methyl and hydroxypropyl groups. These reactions occur under controlled temperature and pressure, ensuring the desired degree of substitution and viscosity. After the chemical reaction, the mixture is neutralized, washed, and purified to remove by-products. Finally, the product is dried, milled, and sieved into a fine powder, resulting in high-quality HEMC. The entire process is meet the requirment for ISO9001, ISO45001 and ISO14001.

Water Retention

Workability

Adhensive Force

It prevents premature drying, ensuring smoother application and a uniform, durable finish.

Durability

HPMC greatly enhances the durability of construction materials by reducing the risk of cracking and improving surface strength. Its excellent water retention ensures proper hydration and curing, preventing shrinkage-related failures. By reinforcing internal cohesion and adhesion, HPMC creates denser, more resilient structures that withstand mechanical stress and environmental changes. 

HPMC significantly improves the workability of construction and coating materials. By enhancing spreadability, it allows mortars, plasters, and adhesives to glide smoothly across surfaces with minimal effort. The improved consistency ensures uniform coverage and reduces drag during application, making the material easier to handle for both professionals and DIY users. In addition, HPMC provides excellent water retention, which prevents premature drying and keeps mixtures workable for longer periods. This extended open time helps reduce waste, allows for better adjustments on-site, and ultimately results in cleaner finishes and higher construction efficiency.

Exhibits excellent resistance to sagging. When used in tile adhesives, it ensures a strong and long-lasting bond. 

Thickening Effect

It enhances mortar viscosity, maintaining stable consistency and preventing ingredient separation during mixing and application.

Open Time

HPMC extends the open time of construction materials, giving applicators more flexibility and efficiency on the job site.
