The surface activity of hydrophilic and hydrophobic fumed silica is shown in figure 2.
Fumed silica can also be treated with bifunctional silanes to introduce functional groups such as vinyl, methacryl, epoxy and amino groups onto the surface to enhance silica-polymer interactions.
The Aerosil fumed silica process is also used for manufacturing other fumed oxides, such as titanium dioxide or aluminum oxide.
To improve mechanical properties such as tensile strength, modulus and tear strength, reinforcing fillers such as fumed silica or precipitated silica are often required in silicone rubbers.
These aggregated particles are what determine the morphology and influence the final properties of fumed silica and the properties seen in various applications.
Proper dispersion of fumed silica results in particles much closer to the aggregate structure originally formed in the flame tube.
It is through the surface silanol chemistry that various chemical treatments may be applied to influence the properties of fumed silica.
As fumed silica does not exist as discrete primary particles, it is more usual to classify these materials by the surface area.
Note that BXS-245 precipitated silica could be compounded at all combinations of silica and process aid loadings; however, fumed silica could not be compounded at high silica and low process aid loadings.
Current commercially available precipitated silicas do not match fumed silica's physical strength/hardness relationship.
These optimum formulations were predicted for both BXS-245 precipitated and fumed silica reinforced silicone rubber compounds.
This comparison indicated that BXS-245 precipitated silica was essentially equivalent to fumed silica's reinforcement performance.
