Carbon black, as reinforcement

White reinforcement This is obtained through the use of silica. Grades are defined by size surface area and method of mannfacture, although there is no universally accepted grading system such as exists for carbon black. A comparison of the effects of silica and carbon black as reinforcing fillers is given in Table 2. In general, unless one needs a non-black rubber, less trouble is experienced with black reinforcement.
