HPMC (hydroxypropyl methyl cellulose)

It is an odorless, tasteless, nontoxic white or off-white powder. Hydroxypropyl methylcellulose is a non-ionic cellulose type ether made of natural polymer material-refined cotton through a series of chemical processes. It is divided into two types: hot-dissolving type and instant-dissolving type.
Hot melt type is mostly used in dry powder, internal and external wall putty powder, mortarand other products. The instant type is mostly used in construction glues, coatings, washingand other liquid products.

• 
  06

  HPMC for Exterior Wall insulation Mortar

  Enhance the adhesion with the wall surface, and can enhance the water retention, so that the strength of mortar can be improved.
  Improved lubricity and plasticity to improve construction performance, Controlling air penetration eliminates micro-cracks in the coating, resulting in an ideal smooth surface.

‌HPMC's production process mainly includes raw material preparation, reaction process, refining process, packaging and storage steps.

1. Raw material preparation:

The raw materials for the production of HPMC mainly include methyl cellulose, propylene oxide, catalyst, etc. When preparing raw materials, it should be ensured that their quality meets the production standards and is formulated in accordance with the formula proportion.

2.‌ The reaction process ‌ :

The methylcellulose is mixed with the catalyst and dissolved by stirring at a certain temperature to obtain a pre-solution.

The pre-solution was mixed with propylene oxide in a certain proportion, the catalyst was added, and the reaction was carried out at a certain temperature and pressure.

The temperature and pressure should be controlled during the reaction process to ensure the smooth progress of the reaction, and pay attention to avoid production safety accidents.

After the reaction is completed, the crude hydroxypropyl methyl cellulose is obtained.

3.‌ refining process ‌ :

The crude product is centrifuged to remove impurities and unreacted raw materials.

The centrifuged solids are washed to remove the remaining catalysts and unreacted propylene oxide.

The washed solid was dried to obtain refined hydroxypropyl methyl cellulose.

‌ 4.Packaging and storage:

The refined hydroxypropyl methyl cellulose is measured and packed to ensure that the product meets the quality standard.

This product is packed in multi-layer paper bags lined with polyethylene layer. Net weight 25KG.
Empty bags can be recycled or incinerated. Unopened packaging can be stored for several years. Open packaging can make the moisture content of this product affected by air humidity. Store in a cool, dry place away from sunlight. Avoid storage under pressure.

HEC vs HPMC

In the world of pharmaceutical and cosmetic formulations, the discourse surrounding hydroxyethylcellulose (HEC) and hydroxypropyl methylcellulose (HPMC) has gained significant interest. Both compounds are widely utilized as thickening agents, stabilizers, and emulsifiers, but they possess distinct characteristics and applications that set them apart.

Hydroxyethylcellulose Powder (HEC) is a non-ionic, water-soluble polymer derived from cellulose. It is characterized by its ability to form clear gels when dissolved in water. HEC is particularly valued for its superior film-forming properties and high rheological performance. This makes it ideal for use in various applications, from skincare products to pharmaceuticals, where a smooth texture and stability are paramount. Hydroxyethylcellulose powder is often chosen for its excellent compatibility with a variety of ingredients and its ability to enhance the sensory feel of the final product.

On the other hand, Hydroxypropyl Methylcellulose (HPMC) is another cellulose derivative that is used extensively in the industry. HPMC powder offers excellent water retention and is less prone to temperature fluctuations compared to HEC. It serves a significant role in both culinary applications—as a thickener in sauces and dressings—as well as in pharmaceuticals and construction, where it acts as a binding agent and helps in maintaining moisture in products like adhesives and cement.

When comparing HEC vs HPMC, the choice depends on the specific requirements of the formulation. For instance, if clarity and film formation are essential, HEC may be the better option; however, if moisture retention is critical, HPMC could be preferred.
