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, it’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.
On the other hand, it’s because surface of nano-silica contains a lot of silicon-based light particles, these particles can form the network structure through hydrogen bonding and van der Waals forces, in the meantime, silica particles will have a strong interaction with polysiloxane molecules to improve the interface condition.
