Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to their physical properties. Solid silica gel is important for molding products. For example: silica gel cover, silica gel kitchen supplies, silica gel buttons, etc., liquid silica gel is mainly used for extrusion molding products, such as silica gel glass bottle, bottle nipple, silica gel tube, etc. Thermal insulation silica gel pad, excellent high temperature professional ability, silica gel (food grade stainless steel plate silica gel) can withstand 200 ℃ high temperature and can be used for a long time, the product production and processing of raw materials in line with SGS standards, according to FDA food grade stainless steel plate silica gel test specification, colorless, tasteless, non-toxic, manufacturers according to the mold production and processing, color, appearance can be customized.
Silica gel raw materials can be divided into general silica gel and climatological silica gel according to their properties. General silica gel is also called stacking silica gel
Color: translucent, milky white, light yellow, dark gray, etc. Compressive strength: 30 ° 40 ° 50 ° 60 ° 70 ° and so on, generally in the middle of 40 ° to 70 °. Density: 1.1-1.12g/cm2 tensile strength: 400%
Scope of application: most of them are middle and low grade silicone products such as mobile phone keyboard, miscellaneous parts, conductive adhesive, etc. Weather gel also known as pure silica gel color: transparent. Compressive strength: 30 °, 40 °, 50 °, 60 °, 70 ° 80 ° and so on, generally in the middle of 40 ° to 60 °. Features: due to the good picture quality of the raw material, the compressive strength is strong. The cost is high. Scope of application: silicone tube, protective cover and other high-grade products with high elasticity.
