KimaCell® HPMC Factory offers an in-depth look into the production, technology, applications, and significance of KimaCell® HPMC, shedding light on the inner workings of Kima Chemical’s world-class HPMC factory.

What is HPMC (Hydroxypropyl Methyl Cellulose)?

HPMC is a non-ionic cellulose ether made from refined cotton linter or wood pulp through a series of chemical processes including etherification with methylene chloride and propylene oxide. It is water-soluble and forms a colloidal solution when dissolved in water. Key properties include:

• Thickening

• Binding

• Film-forming

• Emulsifying

• Water retention

• Lubrication

These properties make it indispensable in industries ranging from construction to pharmaceuticals.

The HPMC Manufacturing Process at Kima Chemical

1. Raw Material Selection

The process begins with the selection of high-purity refined cotton linters, which are rich in alpha-cellulose.

2. Alkalization

Cellulose is treated with caustic soda (NaOH) to form alkali cellulose. This step is crucial for activation and increases the accessibility of hydroxyl groups.

3. Etherification

In this step, the alkali cellulose is reacted with methyl chloride and propylene oxide to introduce methoxy and hydroxypropyl groups.

• Temperature and pressure are tightly controlled.

• The substitution level determines the final viscosity and solubility.

4. Purification

The crude product is purified by washing to remove sodium chloride, by-products, and unreacted chemicals.

5. Drying and Milling

The purified HPMC is dried in hot air dryers and then milled to the required particle size (typically 80–200 mesh).

6. Quality Control and Packaging

• Every batch is tested for viscosity, moisture content, pH, and substitution levels.

• Packaged in 25 kg PE-lined paper bags or bulk bags, suitable for global shipping.
