PPT Silica for Pharmacy
Medicinal PPT silica powder is a new kind of excipient used in pharmaceutical preparations. It is a white powder with high purity and good fluidity. It is an excellent flow promoter in the process of tablet preparation. It can greatly improve the particle fluidity, increase the bulk density, increase the hardness of tablets, shorten the disintegration time and improve the dissolution rate of medicines. Because most of the extracts of Chinese patent medicines are moist and hygroscopic. The micro-powder silica gel has the characteristics of adsorbing water and promoting flow. It is also very suitable for use in capsules and other drugs.
