The present invention is a modified micro-crystalline cellulose (microcrystalline cellulose: MCC) is charged, or a combination to improve the physical properties is as bio-content is increased by the polyurethane and on the production method thereof, and more particularly to non-surface-modified fine with an aqueous or hydrophobic crystalline cellulose (microcrystalline cellulose: MCC) that relates to a combination, the coating reaction, a method of polymerization or polyurethane and polyurethane to be filled. Polyurethane of the present invention has the advantage of improving the tensile strength, yield strength and biomass content and at the same time, increase the surface compatible (compatibility) of the modified microcrystalline cellulose and polyurethane. In addition, the polyurethane of the present invention has the advantage that a high biomass content of the bar, the carbon dioxide emissions that inhibit the use of the oil.
