Activators for Fillers

Inorganic active fillers like silica behave in the elastomer matrix other than the most commonly used filler - carbon black. Activators for Filler enable chemical coupling between filler particles and the polymer matrix. As activators can be used various bifunctional compounds, especially silanes have proved to be very beneficial. In particular those silanes with sulfur-functional groups are mainly used in the rubber industry. For processes in which peroxide vulcanization takes place, vinyl silanes have proven. Aminosilanes find applications for specialty elastomers such as AEM.
