No. The substances that can make rubber vulcanize under certain conditions are collectively called vulcanizing agents.
Under certain conditions, rubber vulcanizing substances are collectively referred to as vulcanizing agents, the so-called vulcanization is to make the rubber linear molecular structure through the vulcanizing agent of the "bridge" into a three-dimensional mesh mechanism, so that the rubber's mechanical and physical properties have been significantly improved.
Rubber vulcanizing agents include elemental sulfur, selenium, tellurium, sulfur-containing compounds, peroxides, quinone compounds, amine compounds, resin compounds, metal oxides and isocyanates. The most commonly used are elemental sulfur and sulfur-containing compounds.
The process of adding sulfur and carbon black to raw rubber and heating it under high pressure to make it into vulcanized rubber is called vulcanization. But to achieve the ideal vulcanization process, in addition to selecting the best vulcanization conditions, the choice of matching agent, especially the choice of accelerator is of decisive significance.
With the increase in the variety of synthetic rubber, vulcanization methods and vulcanizing agent research in-depth, it has been found that there are many non-sulfur compounds also have a vulcanizing effect. Therefore, the term has developed into an industrial term with extended significance. After vulcanization of rubber, change the inherent low strength, little elasticity, cold hard hot sticky, easy to aging and other defects, wear resistance, resistance to swelling, heat resistance and other aspects of the significant improvement, expanding the scope of application.
