Not just any white powder, fumed silica

Fumed silica unusually broad product range is the product of many application possibility of the image.

Without gas oxides, many things in daily life would be unthinkable.Gas phase oxides can be found in the cosmetics industry, for example, where they increase the temperature stability of lipstick.They are also used in the production of high-seas yachts or electronics industries.

Similarly, fumed silica is also used in Silicon dichtungsmassen or car lacquer in the bathtub.For example, gas oxides cause thixotropy, low moisture absorption, mechanical strength and rheological properties optimization.
