Natural rubber is the main polymeric base of aircraft and heavy vehicles tyre rubbercompounds. The effect of the same amount of a silica nanofiller on the curing,mechanical and dynamic properties of natural rubber compounds was investigated.The silica surfaces were pre–treated with bis[3–triethoxysilylpropyl] tetrasulfide(TESPT) to chemically bond silica to rubber. The rubbers were primarily cured byusing sulfur in TESPT, and the cure was optimized by the addition of accelerator andactivator, which helped to form sulfur chemical bonds between the rubber and filler.Different amounts of accelerator and activator were needed to fully crosslink thefilled rubbers. The mechanical and dynamical properties of the vulcanizates improvedsubstantially by the incorporation of the filler in the rubber. This was due to high levelof rubber–filler adhesion and formation of chemical bonds between the rubber andTESPT.<\div>
