High purity Cellulose acetate butyrate with best price CAS NO.9004-36-8

the mcc is a white or shite-like hollow cellulose powder. it main is used as exciplent and

binding agent for producing solid medicants and has good crumbling effect.

the mcc has good flowability and compressible property and extensible in meeting water. it

has strong capillarity. the product can be used for producing drying prowder tablet,and to save

prill and drying process.it can increases hardness of the tablet.especially the mcc is added in

the extract tablet of traditional chinese medicine,it also can speed up crumbling velocity of

the tablet.there for it is a good crumbling agent.after the mcc is mixed in the tablet,the

tablet has many advantages such as not rot edge,not chap,bright surface,stabilityiy in the lingt

and hot and resestance mildew and rot.
