what is silicone?
Silicone is a polymer composed of silicon and oxygen, typically synthesized through a chemical process
Quartz sand
Raw Materials of Silicone
Primary Raw Materials
- 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.
Chemical Reactants
- Chlorine Gas (Cl2): Used to produce silicon tetrachloride.
- Hydrogen Gas (H2): Used to reduce silicon tetrachloride to silane.
Additives and Agents
- 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.
Sources 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.
Manufacturing Process of Silicone
Extraction of Silicon
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
SiO 2 +2C→Si+2CO
Hydrogenation of Silicon
Silicon tetrachloride is reacted with hydrogen gas to produce silane (SiH4) and other hydrides
SiCl 4
Chlorination of Silicon
Metallic silicon is reacted with chlorine gas to produce silicon tetrachloride (SiCl4)
Si+2Cl 2
Polymerization Reaction
Silane is polymerized through controlled chemical reactions to form siloxane chains, which further cross-link to form the silicone network structure
nSiH 4 →(SiH 2 O)n

Types of Silicone
Silicone is classified into several types based on its physical and chemical properties
Liquid - Silicone Rubber (LSR)
High-Temperature Vulcanized (HTV) Silicone
Room Temperature Vulcanized (RTV) Silicone
Our Primary Uses of Liquid Silicone Rubber
Known for its low viscosity and suitability for injection molding, LSR is widely used in the production of high-quality silicone products.
Adult Products
- High Flexibility and Softness: LSR provides the desired flexibility and softness, making it ideal for producing safe and comfortable adult products.
- Non-Toxic and Hypoallergenic: Ensures user safety and comfort, meeting stringent health standards.
Kitchen and Tableware
- Heat and Cold Resistant: Perfect for kitchen utensils and tableware, LSR withstands a wide range of temperatures without degrading.
- Food Safe: Compliant with FDA standards, making it safe for direct contact with food.
Pet Products
- Durable and Chew-Resistant: Ideal for pet toys and accessories, LSR’s durability ensures long-lasting use even with active pets.
- Easy to Clean: Its non-porous surface makes LSR pet products hygienic and easy to clean.
