Detailed Product Description

Activity ultrafine silica, silica of high purity, ultra-fine after treatment, fineness 1200 goal, achieving more than 95% white. After the integrated treatment of high-tech chemical processing and surface activity silane coupling agent. Reduce the original silica, volatile and difficult scattered shortcomings, thereby increasing the activity of ultrafine silica and rubber affinity, wearable and put strong performance. Greatly reduce the pollution and protect the health of workers. Ultrafine 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.
