Some basic knowledge about silicone products

Silicone raw materials can be divided into domestic materials and imported materials according to their sources.

Domestic materials are mainly produced by major manufacturers such as Dongjue, Ruiying, Hongda, Tianyu, New Oriental, and Poly.
The main imported materials include: Shin Etsu and Toshiba from Japan, Dow Corning from the United States, Rodia from France, Wacker from Germany, and so on.

Silicone raw materials can be divided into ordinary silicone and meteorological silicone according to their properties
Ordinary silicone gel, also known as precipitated silicone gel
Color: Translucent, milky white, light yellow, gray, etc.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly between 40 ° and 70 °. 
Density: 1.1-1.12g/cm2
Elongation rate: 400%
Usage: Commonly used in low-end silicone products such as mobile phone buttons, miscellaneous items, conductive adhesive, etc.

Meteorological silicone, also known as pure silicone
Color: Transparent.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly between 40 ° and 60 °.
Density: 1.1-1.12g/cm2
Elongation rate: 600% -700%
Features: Due to its good transparency and strong tensile strength. The cost is relatively high.
Usage: Silicone tubing, protective covers, and other high-end products that require high elasticity.

Silicone raw materials can be divided into solid silicone and liquid silicone according to their physical properties.
Solid silicone is mainly used for molded products. For example, silicone covers, silicone tableware, silicone buttons, etc. Liquid silicone is mainly used for extruded products such as silicone nipples, silicone hoses, etc
