Importancia y uso:

4.1 The rubber-filler interaction needed in silica technology for the rubber industry is based on the use of silane-coupling agents that react with the silanol groups on the surface of the silica during the processing step called silanization. Silane-coupling agents are multifunctional molecules able to create molecular bridges between the elastomer or rubber matrix and the silica surface.
