IS 7020 is a mixture of polymerized sulfur and orthorhombic sulfur, insoluble in rubber, which can prolong the scorch time of rubber compound, prevent the migration of sulfur and improve the viscosity of rubber surface;
IS 7020 is pollution-free and does not change color.
IS 7020 is generally used in unsaturated rubber formula with high sulfur content, especially when the number of added parts exceeds the solubility of soluble sulfur;
IS 7020 is widely used in various tires due to its low migration rate, uniform dispersion and long scorch time;
IS 7020 can also be used in vulcanized rubber products with high performance requirements.
