The relationship between time and temperature
Because the temperature in the rubber vulcanization decision varieties, such as the best natural rubber vulcanization temperature for 145-148 degrees, butyl benzene, butyl rubber, butadiene rubber so the best curing temperature for 148-153 degrees, silicone rubber vulcanization temperature for 170-175 degrees.
Send InquirySulfur vulcanization
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties.

Common Vulcanization Accelerators
Thiazoles. Thiazoles are some of the most widely used primary vulcanization accelerators. They have improved scorch safety and allow for cure at quite high temperatures with short curing time and broad vulcanization plateau. Due to their versatility, they are used for a wide variety of rubber products.

Vulcanization
Vulcanization of polychloroprene. Most conventionally used accelerators are problematic when CR rubbers are cured and the most important accelerant has been found to be ethylene thiourea (ETU), which, although being an excellent and proven accelerator for polychloroprene, has been classified as reprotoxic.
