Insoluble Sulfur IS-HS(High Thermal Stability)
Insoluble Sulfur IS-HS(High Thermal Stability) can improve the resistance to both fatigue and ageing of all kinds of rubber products. It is used as the best vulcanizing agent for rubber. And it is widely used in the manufacture of the rubber chemistry such as tire, rubber pipe, shoes, cable and wire, insulating materials, latex, and all kinds of automobile rubber parts, especially for radial tires.
Advantages of Insoluble Sulfur:
The rubber no need spout frost during storage time. The Insoluble Sulfur is able to keep the unanimous features of the rubber material, and prevent the pollution to rubber product and the models.
With Insoluble Sulfur, there will be no transferring phenomenon between rubber layers that protects the moulding stickiness of the surfaces.
Reduce coking while mix smelting and storage .
Shorten vulcanization time, reduce the dose of sulfur and improve the property of anti-aging of the product.
