IS7520 Introduction
Rubber Vulcanizing Agent IS7520
 
Insoluble Sulfur 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.
