1. Silicone raw materials can be divided into domestic materials and imported materials according to their sources.
Domestic materials mainly include major producers such as Dongjue, Ruiying, Hongda, Tianyu, New Oriental, and Juju.
The main imported materials include: Shinetsu and Toshiba from Japan, Dow Corning from the United States, Rodia from France, Wacker from Germany, and so on.
2. Silicone raw materials can be divided into ordinary silicone and meteorological silicone according to their properties
Ordinary silicone, also known as precipitated silicone
Colors: semi transparent, milky white, light yellow, gray, etc.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° -70 °.
Density: 1.1-1.12g/cm2
Elongation rate: 400%
Usage: It is commonly used in low-end silicone products such as mobile phone buttons, miscellaneous parts, conductive adhesive, etc.
Meteorological silicone, also known as pure silicone
Color: Transparent.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° -60 °.
Density: 1.1-1.12g/cm2
Elongation rate: 600% -700%
Features: Due to its good transparency and strong tensile resistance. The cost is relatively high.
Usage: High grade products that require high elasticity, such as silicone tubes and protective sleeves.
3. Silicone raw materials can be divided into solid silicone and liquid silicone based on their physical properties.
Solid silicone is mainly used for molded products. For example, electronic cigarette protective covers, silicone wristbands, silicone buttons, etc. Liquid silicone is mainly used for extruded products, such as cake molds and food utensils.
