Sioplas process is a type of crosslinking process used for polyethylene materials. YJ-35 peroxide XLPE insulation compound is a type of material used for medium voltage (MV) cable insulation, which is capable of handling voltages up to 35kV. The Sioplas process involves the use of a catalyst to induce crosslinking between the polymer chains, resulting in improved mechanical, thermal, and electrical properties of the material. This process is commonly used in the cable industry to manufacture high-quality insulation compounds for various applications, including MV cables.
