Ultrafine Silica Activity

Activity ultra-fine silica is that silica of high purity, ultra-fine after treatment, fineness 1200 goal, achieving more than 95% white. After the integrated treatment of hig h-tech chemical processing and surface activity silane coupler agent. Reduce the original silica, volatile and difficult scattered shortcomings, thereby increasing the activity of ultra-fine silica and rubber affinity, wearable and put strong performance. Greatly reduce the pollution and protect the health of workers. Ultra-fine silica activity   apply a light-colored, use of color and other rubber products. Furthermore, in a black rubber products can replace 660, 330 carbon black and high-quality, low-cost, rubber production costs can be greatly reduced. Welcome foreign companies to buy.
