It is usually difficult for us to pay attention to the existence of silica gel, but silica gel is widely present in all places of our life, household appliances, precision instruments, clothing and leather, food, medicine and so on. Silicone has so many uses so what is it made of?

What material is silica gel

Literally, silica gel is a porous solid silicon dioxide material with a large specific area. Silica gel property is amorphous material, is a kind of high activity adsorption material. Compared with other similar materials, silica gel has many advantages, such as high adsorption performance, stable chemical properties (in addition to strong alkali, strong acid does not react with any substance), good thermal stability, high mechanical strength, etc..

Silica gel can be divided into: macroporous silica gel, B type silica gel, coarse porous silica gel, fine porous silica gel according to the size of its aperture; According to its composition shape is divided into extruded silica gel and molded silica gel; According to its properties and composition can be divided into organic silica gel and inorganic silica gel two categories.

The use of silica gel

Silicone is mainly used in aviation, cutting-edge technology, military technology departments of special materials and construction, electronics and electricity, automobile, machinery, chemical and light industry, medicine and medical care, etc. Inorganic silica gel is mainly used in desiccant, catalyst carrier, extinction agent, toothpaste abrasive, etc. The toughness and elasticity of silica gel products are very good, and they will not be deformed by external forces, and they are non-toxic, tasteless and colorless, and do no harm to the human body.

Is it safe to use silicone products?

Silica gel because of its good stability and special resistance to high temperature and low temperature, so you can use microwave oven high temperature heating without deformation or release toxic substances, can also be placed in the refrigerator refrigeration!

Because the texture of silica gel is close to human skin, and it is non-toxic and odorless, it is also very healthy for children to use the pacifier made of silica gel. And good silica gel has automatic disinfection function, does not stain, easy to clean, now a lot of fashionable families are using silica gel kitchen utensils, because it can cook with microwave oven completely, save worry and time, more importantly, it will not produce lampblack.

The information about what silicone material and silicone products are safe is introduced here. It is good for us to know more about the things we contact in daily life. I hope these contents can help you.
