Evonik Resource Efficiency offers a large variety of organosilanes for many industrial applications. Evonik silanes are available in liquid form but also as dry liquid in combination with carbon black as carrier and pre-reacted as COUPSIL(R) with different silica types to facilitate the mixing process.

There are many applications for silica and silanes in rubber. Depending on the desired properties Optimum reinforcement is obtained by using silicas in combination with organosilanes such as Si 69®, Si 75®, Si 266® or Si 363TM.

The silanes form a chemical bond between filler and polymer and lead to improved reinforcement and, in particular, to optimized dynamic properties.
