AVICEL® PH-105 NF is a microcrystalline cellulose product used in the pharmaceutical industry. PH-105 has the smallest particle size from AVICEL® PH family and is the most compressible of the PH products. It is useful in direct compression of coarse, granular, or crystalline materials; can be mixed with PH-101 or PH-102 to achieve specific flow and compression characteristics. It has applications in roller compaction; poorly flowable by itself – cannot determine neat compressibility.
