Cellulose is the oldest and most abundant natural polymer on the earth. It is inexhaustible and the most precious natural renewable resource of mankind.

After alkali treatment of refined cotton, cellulose ether is prepared through a series of reactions with methyl chloride as etherifying agent.

Hydroxypropyl methyl cellulose is a cellulose variety with rapidly increasing production and consumption.

It is made of refined cotton after alkali treatment, in the presence of acetone, using ethylene oxide as etherifying agent.

After the cellulose ether in the mortar is dissolved in water, the surface activity ensures the effective and uniform distribution of the cementitious material in the system.

Not all carbohydrates can be digested and converted into glucose. Indigestible carbohydrates are called fiber.

Although cellulose can not be absorbed by the human body, it has a good role in clearing the intestines, and is a healthy food for IBS patients.

Cellulose is the most abundant natural polymer compound in the world. Its raw materials are wood, cotton, cotton linter, wheat straw, rice straw, reed, hemp, mulberry bark, brousso

At normal temperature, cellulose is not soluble in water, nor in general organic solvents, such as alcohol, ether, acetone, benzene, etc.

Cellulose is a macromolecular polysaccharide composed of glucose. Insoluble in water and general organic solvents. It is the main component of plant cell wall.

The water treatment agent polyaluminum chloride product is corrosive. If it is accidentally splashed on the skin, it should be immediately washed with water.
