Silicone is becoming more and more popular because of its environmental properties. Now more and more other material products on the market are replaced by silicone products, if you want to know more about silicone products, you must first start from silicone raw materials.
1. Silica gel raw materials can be divided into domestic materials and imported materials according to the source.
2. Silicone raw materials can be divided into ordinary silicone and rubber silicone according to performance
Ordinary silica gel is also known as precipitation silica gel
Color: translucent, milky white, light yellow, gray, etc.
Hardness: 30 °, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40° -70 °.
Density: 1.1-1.12g/cm2
Elongation: 400%
Usage: The most used are mobile phone buttons, miscellaneous parts, conductive rubber and other 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: 1.1-1.12g/cm2
Elongation: 600%-700%
Features: Due to the good transparency of this material, strong tensile strength. The cost is high.
Application: silicone tube, protective sleeve and other high-grade products requiring high elasticity.
3. Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to physical properties.
Solid silica gel is mainly used for molding products. Such as: silicone sets, silicone tableware, silicone buttons, etc., liquid silicone is mainly used for extrusion products, such as silicone pacifiers, silicone tubes and so on.
4. Food grade silicone
Introduction: Food-grade silicone tube is the use of imported silica gel raw materials, the use of scientific production technology, the use of intermittent method for the production of raw rubber, for the high tear resistance and high transparency of the vapor phase of the rubber, the ultra-high and lower hardness of the mixed rubber, functional rubber and other characteristics of the production of silicone tubes, this product has a wide range of adaptability. Compared with the traditional double 24 vulcanization process of silicone tubes and silicone profiles, it has the advantages of high transparency, tasteless, unchanged yellow, no spray frost, especially to solve the problem of black hose spray frost and blue products fade.
Main features:
1. Non-toxic, odorless, high transparency, no yellowing;
2. Soft, elastic, kink resistance without deformation;
3. No cracking, long service life, cold and high temperature resistance;
4. With higher tear strength and superior electrical performance;
5. More suitable for food machinery silicone tube;
Performance parameters:
1, temperature range: -60℃~200℃;
2, rated voltage: 4000V ~ 10000V;
3, common specifications: Φ0.5mm ~ Φ120mm;
4, hardness: 45~80 degrees;
5, elongation: 500~700%;
6, commonly used colors: transparent, white, black, red, green, blue, gray;
Main uses:
1. Medical equipment connection pipeline, catheter, etc.;
2. Baby bottle straws, catheters, etc.;
3. Electrical instruments and other casing, profile;
4. Food pipe products;
5. Connecting pipe for food machinery;
6. Connecting tubes and conduits for water dispensers, coffee POTS and children's suction cups.
