Vulcanization is a critical process in rubber technology, where cross-linking of polymer chains creates a network that provides strength, elasticity and durability. These properties are essential for demanding applications – such as tire treads – requiring abrasion resistance and mechanical stability. Traditionally, vulcanization is performed by compression molding, which depends on conductive heat transfer. Although reliable, this method is time-consuming, energy-intensive and prone to temperature gradients that reduce cure uniformity in thicker sections. Microwave-assisted vulcanization offers an alternative by heating the material uniformly throughout its volume. This work evaluates its suitability as a scalable process for silica-filled SSBR tire tread compounds.
