What does sulfur do to rubber?

Mineral sulfur is a widely used ingredient to form cross-links between the rubber chains in the vulcanization process. During compounding, a high elastic state of sulfur at temperatures between 40°C and 70°C promotes elongation of its particles and, next, breaking these thin and weak needles into pieces.
