Insoluble Sulfur possessing higher level of thermal stability provides optimum resistance to reversion to the soluble form of sulfur even at elevated temperatures. Such a product would facilitate enhanced bloom protection. High stable DIAMOND SULF ensures more consistent vulcanizing properties and allows storage at relatively higher ambient temperature.
