1. Introduction. Silica is one of the reinforcing fillers widely used in rubber compounds. It not only improves tear strength and abrasion resistance but also reduces rolling resistance in tires when compared to the traditional carbon black,, .Synthetic amorphous silica can be mainly categorized into two types, precipitated silica (PSi) and pyrogenic silica or fumed silica (FSi).
Available in a variety of formulations, the quality, purity and proven performance of PPG's precipitated silica products enables them to function as premium, value-focused alternatives to fumed silica in black, non-black, colored, and translucent silicone rubber compounds by incorporating the following mechanical properties:
Alibaba offers 1,413 fumed silicone rubber material products. About 3% of these are silicone rubber, 1% are rubber sheets, and 1% are other rubber products. A wide variety of fumed silicone rubber material options are available to you, such as chemical auxiliary agent, double components adhesives, and silicon dioxide.

XYSIL® fumed silica is an efficient reinforcement and rheology control additives for silicone rubber. As the surface area of fumed silica increases, so does thickening and reinforcement. However, high surface area XYSIL® fumed silica require high shear dispersion equipment to achieve optimal performance.

Hydrophilic Fumed Silica is a white colloidal powder. This fumed silica has properties that include much or less of the following: reinforcing filler in elastomers, anti-settling or anti-sagging agents, improved free flow and anti-caking characters of powders, transparency in unsaturated polyester resins, and reinforcing filler in elastomers, rheology and thixotropy control of liquid systems .
