产品名称NAME：Cellulose Fiber（纤维素纤维）
产品描述PRODUCTION DESCRIPTION：
Cellulose fiber is a chemical material extracted from natural wood materials. Owing to water absorption characteristic and three-dimensional structure, the water inside can be transferred to the surfaces or interfaces of friction products quickly, which makes the bond strength and surface strength significantly increased. Its wood fiber dimensional stability and thermal stability contribute to stabilizing the coefficient of friction for friction materials.
