Silicone is more and more popular because of its environmental performance. Now more and more other products on the market are replaced by silicone products. If you want to know more about silicone products, you first need to start with silica raw materials.
1. Silicone raw materials according to the source can be divided into domestic materials and imported materials. Domestic materials are: East Jazz, Ruiying, HTC, Tian Yu, New Oriental, polymerization and other larger producers. Import materials are: Japan's Shin-Etsu, Toshiba, Dow Corning, France Luo Diya, Germany WACKER and so on.
2. Silicone raw materials according to the performance can be divided into ordinary and meteorological silica gel ordinary silica gel, also known as precipitation Color: translucent, milky white, light yellow, gray and so on. Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° - 70 °. Density: 1.1-1.12g / cm2 Elongation: 400% Uses: used more than the phone buttons, miscellaneous pieces, such as conductive plastic middle and low silica products. Weather silica gel, also known as pure silica gel Color: transparent. Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° and 60 °. Density: 1.1-1.12g/cm2 Elongation: 600%-700% Characteristics: Due to the good transparency of this material, strong tensile strength. High cost. Uses: silicone tube, protective sleeve and other high-end products require high flexibility.
3. Silicone raw materials by physical properties can be divided into solid and liquid silicone gel. Solid silica gel is mainly used for molded products. For example: silicone case, silicone tableware, silicone keys, etc. Liquid silicone is mainly used for extrusion products, such as silicone pacifiers, silicone tubes and so on.
