Silicone is a polymer composed of silicon and oxygen, typically synthesized through a chemical process
Quartz sand
These raw materials are essential for producing high-quality silicone with specific properties tailored to various industrial and consumer applications
Silicon Dioxide (SiO2): Sourced from quartz sand, it serves as the primary raw material for silicon.
Metallic Silicon (Si): Produced by reducing silicon dioxide, this is essential for subsequent chemical reactions.
Chlorine Gas (Cl2): Used to produce silicon tetrachloride.
Hydrogen Gas (H2): Used to reduce silicon tetrachloride to silane.
Catalysts and Cross-Linking Agents: Used to control the polymerization and cross-linking of siloxane chains to form the final silicone structure.
Additives: Including pigments, plasticizers, and antioxidants, these enhance the performance and appearance of silicone.
The primary component of silicone is silicon dioxide (SiO2), which is widely found in nature in the form of quartz sand or sandstone. The process of manufacturing silicone involves extracting silicon from these natural resources and then synthesizing it through a series of chemical reactions.
Silicon is extracted from quartz sand. This process usually involves heating quartz sand with carbon in an electric arc furnace to produce metallic silicon and carbon dioxide
Silicon tetrachloride is reacted with hydrogen gas to produce silane (SiH4) and other hydrides
Metallic silicon is reacted with chlorine gas to produce silicon tetrachloride (SiCl4)
Silane is polymerized through controlled chemical reactions to form siloxane chains, which further cross-link to form the silicone network structure
Silicone is classified into several types based on its physical and chemical properties
Known for its low viscosity and suitability for injection molding, LSR is widely used in the production of high-quality silicone products.
