Some introduction of silica gel raw materials

2022-03-22

Because silica gel is environmentally friendly, it is becoming more and more popular. At present, more and more things are made of silica gel. In order to systematically understand silica gel products, we should first start to understand silica gel raw materials.

1. Silica gel raw materials can be divided into domestic materials and imported materials according to the source.


Domestic materials are mainly: East Jue, Rui Ying, HONGda, tianyu, New Oriental, polymerization and other big manufacturers.


The main import materials are: Japan Shinetsu, Toshiba, The United States dow Corning, France Rhodia, Germany Wacker and so on.


2 silica gel raw materials according to the performance can be divided into ordinary silica gel and meteorological silica gel


Ordinary silica gel is also known as precipitated silica gel


Color: translucent, milky white, light yellow, gray, etc.


Hardness: 30 °, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40° -70 °.


Density: 1.1 to 1.12 g/cm2


Elongation: 400%


Uses: the most used are mobile phone keys, miscellaneous parts, conductive adhesive and other middle and low grade silicone products.


Meteorological silica gel is also known as pure silica gel


Color: transparent.


Hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40° -60 °.


Density: 1.1 to 1.12 g/cm2


Elongation: 600%-700%


Features: Due to the good transparency of this material, strong tensile resistance. The cost is high.


Uses: silicone tube, protective sleeve and other high-grade need high elasticity products.


3 silica gel raw materials can be divided into solid silica gel and liquid silica gel according to the physical properties.


Solid silica gel is mainly used for molding products. For example: silica gel set, silica gel tableware, silica gel buttons and so on, liquid silica gel is mainly used for extrusion molding products, such as silica gel pacifier, silica gel tube and so on.
