FEATURES
● All raw materials we adopt the Xinjiang and Central Asia cotton linters, the cotton linters has high maturity, refined cotton made by the cotton linters has high alpha cellulose content, etherification reaction to reduce polymerization degree in small amplitude. ● Because of the use of advanced and reasonable production technology, refined cotton whiteness could reach 87%, the polymerization degree can reach more than 2800, low content of impurities, without other fiber (no three wire.)APPLICATION
Refined cotton is the main material for manufacturing nitrocellulose (nitrocellulose) , widely used in food, medicine, daily chemical, plastics, electronics, paper making, metallurgy, aerospace and other fields, known as "special industrial monosodium glutamate".
