SPECIAL MOLECULAR WEIGHT CHITOSAN
The amino group in the molecular structure of chitosan is more active than the acetylamino group in chitin, which makes the polysaccharide have excellent biological function and can be chemically modified. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.
In the manufacturing process, the relative molecular weight of chitosan is usually expressed by the viscosity.Low molecular weight N-succinyl-chitosans with different degrees of substitution were synthesized by controlling reaction temperature, reaction time, and the molar ratio of the low molecular weight chitosan to succinic anhydride.
Usually,finished chitosan product needs deacetylation,filtration,dessication,crushing and a lot process then gets refined.
Special molecular weight chitosan is refined from high quality product and the range of molecular weights is from 20,000 to 300,000.Specifically,molecular weights are 300,000 , 250,000 , 200,000 , 150,000 , 100,000 , 50,000 and 20,000/This product is suitable for many applications in different fields and some indexes such as degree of deacetylation can be customized.
Deacetylation degree and other indicators can be produced according to customer demand.
