Raw Materials Raw Materials

Raw Materials

The major raw materials required for the production of cellulose ethers include refined cotton and some commonly used chemical solvents such as propylene oxide (PO for short), chloromethane, liquid soda, caustic soda, ethylene oxide, toluene and other auxiliary materials. The upstream industry enterprises in this industry include refined cotton and some chemical companies. Fluctuations in the prices of the major raw materials mentioned above will have varying degrees of impact on the production costs and selling prices of cellulose ethers.

Production Process Production Process

Production Process

With the advanced international production Technology, we have introduced German horizontal kettle“one - step”production process. There are two automatic production line, 8 etherification kettles. The cellulose products have been widely used in industry chemicals, such as construction building materials and detergent grade.
