Brief Introduction:
Microcrystalline cellulose (MCC) is the product of natural cellulose hydrolyzed by acid to the limit degree of polymerization. Its color is white or near white, odorless and tasteless. The particle size is generally about 2-80 μm. It has low density, high modulus; with the advantages of renewable, degradable, and wide sources, it can be used as a reinforcing agent for composite materials to improve the performance of materials.
