Wood Cellulose Fiber, also named Lignocellulose, Xylem Fiber, is a environment friendly products, gained from replenishable raw materials. Kundu Chemical Wood Cellulose Fiber KDT800M(Average fiber length 800㎛), especially can be used for wood-base-type clay products. It is a water-insoluble natural fiber with excellent flexibility, dispersibility and chemical inertness. It is microscopically in the form of long microporous fibers, has a large specific surface area, is rich in plant chemical bonds, and has good toughness, dispersibility, chemical inertness, and good hygroscopicity. Adding to clay products can enhance crack resistance, enhance material toughness, improve the tensile strength.
