The production process and properties of the domestic insoluble sulfur (IS) OT20 were presented. The production process was based on the direct melting method, but the temperature was elevated to 620~700℃. The product OT20 possessed high content of insoluble sulfur, good high temperature stability and similar dispersibility as the imported insoluble sulfur. When OT20 was applied in the compounds of the belt and carcass of all-steel belt radial tire, the processing property and physical properties of the compounds met the production requirements, and the blooming did not occur at all in the semi-ifnished products.
