What Raw Materials are Needed to Produce High Purity Sodium Carboxymethyl Cellulose
For high purity sodium carboxymethyl cellulose production, all the raw materials needed are refined cotton, wood pulp, chloroacetic acid, hydrochloric acid, alcohol and liquid alkali. Carboxymethyl cellulose sodium powder was obtained by etherification, alkalization and neutralization. After several times of alcohol washing, washing the excess salt, and then sieving, sodium carboxymethyl cellulose with different mesh number and fineness was obtained.

The refined cotton is mostly produced in China, which is divided into edible grade refined cotton and industrial-grade refined cotton.

Food grade CMC must be produced with edible grade refined cotton before it is edible and the price is high. Wood pulp is mostly imported from Canada and other countries. Good wood pulp polymerization degree can reach the level of edible grade refined cotton of general quality.

In recent years, due to the intensification of the state's efforts to rectify the chemical industry, the shortage of raw materials and the rise in prices have been caused first, followed by a chain reaction, resulting in an increase in the cost of finished factories. With the impact of shutdown and production restrictions, prices soared.
For the price rise caused by government orientation and market indigestion, according to the principle of the market economy, it must be digested and absorbed by the market itself. Therefore, for the price rise, customers will initially find it difficult to accept, until the inventory is exhausted, plus the upward trend.

Jining Fortune Biotech Co., Ltd., mainly engaged in the production and sales of carboxymethyl cellulose and polyanionic cellulose products, is the main sodium CMC supplier in China.

Jining Fortune Biotech Co., Ltd., the preferred choice for the purchase of sodium carboxymethyl cellulose, is in line with the business purpose of "win-win in good faith", providing high-quality products and excellent services for the vast number of new and old customers. We sincerely welcome colleagues from all walks of life to come and negotiate business.
