What is the  Chemical cross-linking Method for compounds ?

Chemical cross-linking is a method used to manufacture cable compounds, which are materials used to insulate and protect cables in electrical systems. This method involves the use of a chemical agent, such as a cross-linking agent, to create a network of chemical bonds between polymer molecules, resulting in a material that is more stable, durable and have improved electrical properties than the original polymer.

One of the most commonly used chemical cross-linking agents is dicumyl peroxide (DCP). DCP is added to the polymer in small amounts, typically between 0.1 to 2 percent, before the polymer is extruded or molded. The DCP decomposes at the high temperature of the extruder or mold and the resulting free radicals react with the polymer to create cross-links. The cross-links are responsible for the increased mechanical and electrical properties of the final polymer compound.

Another commonly used chemical cross-linking agent is sulfur. Sulfur is added to the polymer as a cross-linking agent, typically between 0.1 to 2 percent. The sulfur reacts with the polymer during the extrusion or molding process, creating cross-links. Sulfur cross-linked compounds are known for their improved electrical properties, high temperature resistance and excellent mechanical properties.

A third commonly used chemical cross-linking agent is silane. Silane is added to the polymer
