Abstract
The claimed invention refers to the development of rubber recipes to improve essential properties related to correlated rubber compounds. Silica gel is added to the rubber compound as a reinforcing agent, partially replacing some of the precipitated silica. The use of silica gel for the pneumatic market provides improved tear resistance, elongation and adhesion performance, and improves adhesion of the tire on wet surfaces.
