accelerator for rubber vulcanization
Vulcanization Accelerators CROW. Accelerators for Sulfur Vulcanization of Rubbers. Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in ...
