Silicone is becoming more and more popular due to its environmental performance. To understand the knowledge of silicone products, you must start with silicone raw materials.
1.The silica gel raw materials can be divided into ordinary silica gel and weather silica gel according to their performance.
Ordinary silica gel
Color: translucent, milky white, light yellow, gray, etc.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, etc., commonly used between 40 ° -70 °.
Density: 1.1-1.12g / c
Elongation: 400%
Uses: More commonly used are low- and middle-grade silicone products such as mobile phone keys, miscellaneous pieces, and conductive adhesives.
Weather rubber
Color: transparent.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° -60 °.
Features: As this material has good transparency and strong tensile strength. High cost
Uses: Silicone tubes, protective sleeves and other high-end products that require high flexibility.
2. The raw materials of silica gel can be divided into solid silica gel and liquid silica gel according to their physical properties.
Solid silica gel is mainly used for molded products. For example: silicone cover, silicone tableware, silicone buttons, etc. Liquid silicone is mainly used for extrusion molding products, such as silicone nipples, silicone tubes, etc.
Insulated silicone pad, excellent high temperature resistance, silicone (food-grade silicone) can withstand high temperatures of 200 ° C and can be used for a long time. The raw materials for this product meet the SGS standard and pass the FDA food-grade silicone test standard. Mold production, color and shape can be customized.
