Nanometer Silicon Dioxide Used For Rubber

We are offering to our clients a wide spectrum of Nanometer Silicon Dioxide Used For Rubber. As we know, mechanical strength of pure rubber is low. However, the tensile strength of vulcanized rubber can be improved from 0.35MPa to 14MPa and reinforcement rate can be 40 times higher than common rubber when the rubber is mixed with nano-silica to reinforce mechanical strength. It shows our nanometer silicon has a decisive role in the final performance in the use of silicone rubber.

Application:
1. As a reinforcing agent, anti-aging agent, our nano-silica can be used in rubber products to increase strength, toughness, anti-aging, anti-friction of rubber products and prolong life and other functions
2. nano-silica is a effective reinforcing filler of RTV silicone rubber, can significantly improve their strength. The reasons are as follows:
On the one hand, ita s because of the small particles and large surface area of nano-silica.Usually,the smaller the particle size is, the larger the surface area is, the higher the structure is, the better reinforcing effect is, the higher the strength and hardness of vulcanized rubber is.
