The main composition and application of liquid silicone products

Liquid silicone rubber is relative to solid high-temperature vulcanized silicone rubber. It is a liquid rubber with good fluidity, fast vulcanization, safer and more environmentally friendly, and can fully meet food-grade requirements. Liquid silicone products are formed by injection molding of liquid silicone. The products are soft and are widely used in simulating human organs and medical silicone breast pads because of their soft characteristics.

Liquid silicone products are loved by many consumers in the market. Its advantages are: non-toxic, odorless, non-oxidizing, non-deformation, and strong repeated use. So, do you know the main ingredients and applications of liquid silicone products?

The main components of liquid silicone:

1. Liquid silicone is a highly active adsorption material, which is an amorphous substance and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvents, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkalis and hydrofluoric acid.

2. Various types of silicone form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

3. According to the size of its pore size, silicone is divided into: macroporous silicone, coarse pore silica gel, B-type silica gel, fine pore silica gel. Due to the difference in pore structure, their adsorption properties have their own characteristics.

4. Coarse-pored silicone has a higher adsorption capacity when the relative humidity is high, while fine-pored silica gel has a higher adsorption capacity than that of coarse-pored silica gel when the relative humidity is low. Type B silica gel has a larger pore structure between coarse and Between fine-pored silica gel, the adsorption capacity is also between coarse and fine pores. Macroporous silica gel is generally used as catalyst carrier, matting agent, toothpaste abrasive and so on. Therefore, different varieties should be selected according to different uses. After silica gel absorbs water, it can be regenerated by exposure, roasting, air drying and other methods.

The main use of liquid silicone:

Liquid silicone has a strong adsorption effect, can quickly and effectively adsorb the moisture in the sealed package, is chemically stable, non-toxic and harmless; in recent years, continuous innovation and development, various silica gels have also been widely used in drug purification, DNA Separation, food drying, high-precision electronics, high-grade cosmetics, sewage purification, beer purification, high-grade paint and resin production or preservation. Liquid silicone is suitable for the production of high-transparent pacifiers and other baby products, daily necessities, silicone toothbrushes, teethers, diving goggles and leisure products.
