However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors.

Vulcanization & Accelerators - Nocil

Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C
