产品名称NAME：Rock Wool（岩棉纤维） 产品编号PRODUCT CODE：BL-YM-160
产品描述PRODUCTION DESCRIPTION：
Rock wool is a friction raw material reinforced fiber, it is an asbestos substitute material, which helps to substantially bring down the cost of asbestos free friction products. Compared with glass fibers and wollastonite, it can reduce brake noise as well as improve the wear resistance. It is a clean engineering mineral fiber. Due to its short length, it is easier to open during dry mixing, and it has excellent dispersion properties when mixed with various fibers. It has a high degree of biology degradation performance.
