Cellulose Ethers

As a switch to continuous twin screw granulation is quickly gaining momentum, the suitability of binders needs to be evaluated towards this novel granulation process.  Binder suitability depends on binder effectiveness, which is affected by binder attributes. These critical attributes need to be…
