Insoluble sulfur is a new rubber vulcanizing agent used as the best vulcanizing agent for rubber.
Advantages:
1. The rubber doesn't spout frost during storage time. It can keep the
uniform function of the rubber material. And it prevents the pollution to
the rubber product and the models.
2. It has no moving phenomenon between rubber layers, and can protect the
surfaces to form stickiness. Reduce coking during the mix smelting and
storage time.
3. Shorten vulcanization time, reduce the consumption of sulfur and
improve the rubber products anti-oxidize property.
