Profiling Analysis of Polysulfide Silane Coupling Agent

Recently, in line with the oil-conservation movement, silica, as a non-petroleum resource, is increasingly used as a tire reinforcement filler. Fillers are typically mixed with rubber compounds used in tires to enhance reinforcement of the tire. Because silica has a hydrophilic silanol group on its surface, when added to the lipophilic elastomer rubber, it readily coheres to the rubber without actually bonding to the rubber molecule. Thus, the processibility and mechanical strength of the rubber compound is degraded, greatly affecting tire performance. For this reason, processing with a silane coupling agent is conducted to avoid this shortcoming.Recently, in line with the oil-conservation movement, silica, as a non-petroleum resource, is increasingly used as a tire reinforcement filler.
