Use: Insoluble sulfur is mainly used in the rubber industry. When used as a vulcanizing agent, the surface of rubber products is not sprayed with frost, which can enhance the steel-adhesive adhesion. Because it is evenly distributed in the rubber, it can ensure the vulcanization quality. Therefore, it is widely used in tire carcass rubber, especially in all-steel radial tires. It can also be used in rubber materials for rubber products such as cables, rubber rollers, rubber shoes, etc.

Packaging: 25 kg, plastic woven bag lined with PE bag, paper-plastic composite bag, kraft paper bag.
