Refined cotton,cotton linters pulp as ether, ester products, known as industrial
MSG in the world.It is a fiber material made of linters by alkaline cooking.
It can be used for industrial production of nitrocellulose, cellulose ether:CMC,
MC,EC,HPC,CEC etc. and acetate. We adopting 100% Xinjiang cotton linters as raw
material, alkaline cooking, oxidizing bleaching refined a uniform loose, no wood,
bamboo shavings, sand, oil, metals and other impurities on the white floc.
The main chemical ingredient is cellulose, lignin and hemicellulose. It is composed
of carbon, hydrogen, three kinds of elements, the oxidizing bleaching subtracting
refined cooking and refined cotton, has a low impurity content, the higher swelling
capacity and response, preferably a polymerization degree and whiteness
Our company refined cotton product features:
1. 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.
2 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.)
3 Our company refined cotton has following series goods:
M series: M5、M15、M30、M60、M100、M200、M400、M500、M650、M1000
Ether cellulose grade
X series:X15、X30、X60、X100、X200 Nitrocellulose
C series:C100、C200 Acetate grade
C series refined cotton standard specification for ACETATE GRADE |
