[0002] Silicone is an elastomeric material made from silicon raw materials. It has excellent tensile resistance, wear resistance, high temperature resistance, corrosion resistance and other properties. It is widely used in electronics, medical, construction, automobile and other fields. The main raw materials of silicone are silica and quartz sand. The raw materials need to be crushed, screened and other processes to ensure that the purity and particle size of the raw materials meet the requirements. The production process of silicone needs to control the quality of the raw materials and the parameters of the production process to ensure stable and reliable product quality.
