Product Applications
1. Used as a binder: In the pharmaceutical field, this product is mainly used as a binder, such as for tablets, granules, and pellets. The dosage is generally 1%-5% of the drug weight, and RT-L or RT-J type is preferred. It can increase the stability and hardness of the tablets, and the dissolution time is better than that of tablets using raw materials as binders.
2.Used as a film coating material for tablets. H-HPC has excellent film-forming properties, producing tough and elastic films that are comparable to plasticizers. It has a very low equilibrium moisture content. By mixing it with other heat-resistant coating agents, the stability of the film can be further improved. The RT-L type is generally preferred.
