◆ Performance:
-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 the color.
◆ Application:
-IS
7020 is generally used in unsaturated rubber formulations 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
requirements for performance.
◆ Packaging: Paper/plastic packages with a net weight of 25kg per package.
◆ Transportation
Condition: Meet the general transportation conditions of chemicals and avoid
mixing with alkaline substances.
