The main components of liquid silicone

Liquid silicone products are loved by many consumers in the market, with the advantages of being non-toxic, odorless, non oxidizing, non deformable, and highly reusable. Widely used in our daily necessities and mother and baby products, such as pacifiers, bottles, silicone toothbrushes, dental glue, and so on. What are the main components of liquid silicone? It has been a hot topic on the internet. Today, I will summarize the main components of liquid silicone.

1. Liquid silica gel is a highly active adsorption material, belonging to the amorphous state. Its chemical molecular formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic and odorless, chemically stable, and does not react with any substance except strong bases and hydrofluoric acid.

2. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

3. Silicone can be divided into macroporous silicone, coarse porous silicone, B-type silicone, and fine porous silicone based on their pore size. Due to their different pore structures, their adsorption properties have their own characteristics.

4. Coarse porous silica gel has a higher adsorption capacity under high relative humidity, while fine porous silica gel has a higher adsorption capacity than coarse porous silica gel under low relative humidity. However, B-type silica gel has a pore structure between coarse and fine porous silica gel, and its adsorption capacity is also between coarse and fine pores. Macroporous silica gel is generally used as a catalyst carrier, matting agent, toothpaste abrasive, etc. Therefore, different varieties should be selected based on different uses. After silica gel adsorbs water, it can be regenerated by methods such as exposure, roasting, and air drying.

5. Main uses of liquid silicone: Liquid silicone has a strong adsorption effect, which can quickly and effectively adsorb water inside sealed packaging, has stable chemical properties, and is non-toxic and harmless; In recent years, with continuous innovation and development, various types of silicone have also been widely used in drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification, beer purification, advanced coatings, and resin production or preservation.
