Rubber silanes - driven by our passion for high performance applications

Evonik has been active in the field of sulfur-functional organosilanes since the early 1970s. The first and still most important of these products Si 69® was developed as far back as 1971. In particular, the manufacture of tires was revolutionized by the introduction of the Silica/Silane- technology. Two of the three most important properties (rolling resistance, wet grip and abrasion resistance) are significantly improved by the Silica/Silane-system. Wet grip and rolling resistance were ameliorated largely with silica and silane without negatively changing the mileage of a tire. This was called the extension of the magic triangle.


Evonik Resource Efficiency manufactures silane products in several locations worldwide.
