Can be applied to rubber products. As a reinforcing agent and anti-aging agent, nano-silica can be used in rubber products to improve strength, toughness, anti-aging, anti-friction fire, prolong life, and other functions. The mechanical strength of pure rubber is very low. When the nano-silica reinforcing filler is mixed, the microcrystalline area with silica as the crystal core is formed, which increases the physical cross-linking point and is more prone to crystallization. The strength of rubber can be significantly improved. It can be seen that the use of nano-silica filler plays an important role in the final performance of silicone rubber. https://www.nanotrun.com/nano-silicon-dioxide-powder-sio2-nanoparticles-cas-14808-60-7-p00899p1.html
