Top Cellulose Ether Manufacturers in China

As one of the leading HPMC cellulose ether manufacturers in China, we at HPMC Cellulose Ether pride ourselves on producing high-quality cellulose ethers that cater to a wide range of applications. In this article, we will delve into the properties, manufacturing process, applications, particularly in the construction field, and specifications of HPMC (Hydroxypropyl Methylcellulose) cellulose ether.

What is HPMC Cellulose Ether?

Hydroxypropyl Methylcellulose (HPMC) is a non-ionic, water-soluble cellulose ether derived from natural cellulose. It is used extensively in various industries due to its unique properties, such as solubility in water, thickening, gelling, film-forming, and binding capabilities.

Properties of HPMC Cellulose Ether

1. Water Solubility: HPMC dissolves easily in cold or hot water, forming clear or slightly turbid solutions.
2. Thickening Agent: It is widely used as a thickener in various formulations.
3. Film-Forming Ability: Provides excellent film-forming properties.
4. Binding Properties: Acts as an effective binder in various applications.
5. Adhesion: Offers good adhesive properties, making it ideal for use in adhesives and coatings.
6. Thermal Gelation: Exhibits thermal gelation properties, forming gels upon heating and reverting to solutions upon cooling.

Manufacturing Process of HPMC Cellulose Ether

The production of HPMC involves several steps:

1. Purification: The raw cellulose is purified to remove impurities.
2. Alkali Treatment: The purified cellulose is treated with alkali to form alkali cellulose.
3. Etherification: The alkali cellulose is reacted with etherifying agents such as methyl chloride and propylene oxide to produce HPMC.
4. Neutralization: The reaction mixture is neutralized to remove excess alkali.
5. Purification: The HPMC is purified by washing and filtration.
6. Drying: The purified product is dried to obtain the final HPMC product.

Applications of HPMC Cellulose Ether

HPMC cellulose ether finds applications in a variety of industries, including:

1. Construction: Used in tile adhesives, cement renders, plasters, and mortars for its water retention, workability, and adhesion properties.
2. Pharmaceuticals: Acts as a binder, film former, and controlled-release agent in tablet formulations.
3. Food Industry: Used as a thickener, stabilizer, and emulsifier in food products.
4. Paints and Coatings: Enhances the rheology and stability of paints and coatings.
5. Cosmetics: Used in creams, lotions, and shampoos for its thickening and stabilizing properties.
6. Oil Drilling: Serves as a viscosity modifier and fluid loss reducer in drilling fluids.

Application of HPMC Cellulose Ether in the Construction Field

In the construction industry, HPMC cellulose ether plays a crucial role in improving the performance of building materials. Its applications include:

1. Tile Adhesives: Enhances the adhesion and workability of tile adhesives.
2. Cement Renders and Plasters: Improves water retention, workability, and crack resistance.
3. Self-Leveling Compounds: Provides excellent flow and leveling properties.
4. Mortars: Enhances the workability, water retention, and strength of mortars.
5. Gypsum Products: Improves the workability, adhesion, and setting time of gypsum-based products.

Specifications of HPMC Cellulose Ether

The specifications of HPMC cellulose ether vary depending on the type and application. Common specifications include:

1. Viscosity: Measured in mPa.s, varies depending on the application requirements.
2. Particle Size: Typically ranges from 80 to 100 mesh.
3. Moisture Content: Usually less than 5%.
4. pH Value: Typically ranges from 6.0 to 8.0.
5. Degree of Substitution (DS): Indicates the average number of ether groups per anhydroglucose unit, affecting solubility and viscosity.
