In recent years flint - acid fillers became important raw materials for the tire industry.
Kremnekislotny fillers were pervonaalno used for strengthening of the light-painted rubber products in which technical carbon could not be obviously applied. Now "silika" is applied in tires together with technical carbon and silane that promotes considerable decrease in resistance to swing and improvement of controllability on roads. Besides, "silika" plays an important role as the matting substance at production of paints and coverings, and also improves the covering ability of emulsion paints.
Silika is used as the strengthening filler in rubber industry for the most different products - from high-quality soles of footwear and rubber products to tires with a low resistance to swing, high coupling with the wet road and excellent winter characteristics.
Artificially received "silika" represents thin loose white powder, is in certain cases delivered in the granulated look. Its particles are amorphous and therefore with - are vershenno harmless in comparison with crystal particles. Contains in the chemical composition of "silika" pribliz. 99% of dioxide of silicon (SiO2).
