Detailed Product Description

Features:1) 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 silicone coupling agent2) 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 workers3) Ultrafine silica activity applies 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 Specifications: 1) Name: ultrafine silica activity indicators 2) Heating reductions: 1.0 3) NBP absorption: 0.5 - 1.0 4) pH: 7 - 9 5) 45vm% residue screen: 0.1 6) Tensile strength MP: 19 7) Elongation at break: 500%8) 300% tensile strength MP: 2.0 - 6.0
