ultrafine silica activity

الوصف

Activity ultrafine silica, silica of high purity, ultra-fine after treatment, fineness ***0 goal, achieving more than *5% 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 **0, **0 carbon black and high-quality, low-cost, rubber production costs can be greatly reduced. Welcome foreign companies to buy.
