The high sulfur (HS) vulcanization system gives rise to higher apparent crosslink density and improvement in modulus, resistance to abrasion, compression set, heat buildup, rebound resilience, and dynamic set than that of the low sulfur (LS) vulcanization system. Tensile strength, tear strength, and flexing resistance were found to be better for the low sulfur (LS) vulcanization system. Rupture energy during tensile and tear failure determined from the Universal Testing Machine (Instron 1195) also reveals a similar phenomenon. Studies on fracture mode during different types of failure have been done by using a scanning electron microscope (SEM).
