No poison. Silica gel is non-irritating, non-toxic, non-allergic and has little rejection. It has good physical and chemical properties, and can maintain its original elasticity and softness when it comes into contact with body fluids and tissues, 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.

The main component of silica gel is silica, which is chemically stable and does not burn. Silica gel is an amorphous silica, and the dust content in the workshop should be controlled at no more than 10 mg/m3. Strengthen ventilation and wear a mask when operating.

Extended data

Silica gel type:

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.
