Silicone molds are non-toxic. Because it is composed of silica gel, silica gel has no irritation, toxicity, allergic reaction and little rejection to human tissues; It is a very stable material with good physical and chemical properties. In the process of contact with body fluids and tissues, it can maintain its original elasticity and softness and is not degraded. It is a fairly stable inert substance. It can resist high temperature and disinfect. Convenient processing and molding, easy processing, carving and molding, and convenient use. Except that strong acid and alkali will affect silica gel, it is no problem for daily use.

Nowadays, many silica gel molds are made of silica gel, which has applications in various fields. Because of its environmental protection and safety characteristics, it has replaced plastics and other materials.

Silica gel is generally divided into two types:

1, inorganic silica gel

Inorganic silica gel is an amorphous substance, and its chemical molecular formula is mSiO2 nH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid.

2. Silica gel

Silicone gel has the basic characteristics of low surface tension, low viscosity-temperature coefficient, high compressibility and high air permeability, and has excellent characteristics such as high and low temperature resistance, electrical insulation, oxidation stability, weather resistance, flame retardancy, hydrophobicity, corrosion resistance, innocuity and tasteless, and no physiological inertia, and is widely used in aerospace, electronic and electrical, construction, transportation, chemical industry, textile, food, light industry and medical treatment.

From all aspects, silica gel itself is a non-toxic and high-quality product, which has no harm to the body and can be used with confidence. Silicone is the most common material in our daily life, especially in plastic surgery hospitals. Silica gel is usually used to make common key parts such as chin, chest and nose. Many people use this to change the shortcomings of their own province, so it is deeply loved by the public and can be used directly. Silica gel is forbidden to eat, because it is very stable and difficult to have chemical reactions. If used, it will damage the stomach.

De yi yang yang silicone mold

Silica gel is insoluble in water and any other solvent, and it is nontoxic and tasteless. At present, there are many silica gel manufacturers in the market, and many silica gel products are made. Silica gel made by conscientious merchants is non-toxic and tasteless, but some silica gel merchants will add some chemical reagents, which will produce irritating odor and be harmful to human body. It is very important to choose a good silicone manufacturer, and the silicone produced by the manufacturer is trustworthy.
