Product Description

The mechanical intensity of pure rubber is very low. But rubber’s tensile strength will be increase from 0.*5MPa to *4MPa after adding some wanjing nanometer silicon dioxide (VK-SR*1).The rate of tensile strength increases more than *0 times , but other rubbers can increase 1.***0 times only. Nanometer silicon dioxide (VK-SR*1)is the best filling used to increase the strength of high-temperature sulfurate silicone. Nanometer silicon dioxide can increase the strength of rubber effectively. Adding nanometer silicon dioxide (VK-SR*1)in rubber will form a microcrystalline area where silicon dioxide are nucleus. And then the physical junctions will increase. The tensile strength will increase more than *0 times in this way.
