Is silica gel toxic at high temperatures?

Issuing time:2018-09-18 11:15Author:余洪

No, the silicone itself is non-toxic.

The material used for the silicone heated sheet is imported flame retardant silica gel, although it will not burn when there is an open flame.

Silicone electric heating plate is a silicone product made of flame retardant material. It will not burn when exposed to fire.


Silicone alias: Silicic acid gel is a highly active adsorbent material, which is an amorphous substance with a chemical molecular formula of mSiO2·nH2O. It does not react with any substance except strong alkali and hydrofluoric acid, and is insoluble in water and any solvent. It is non-toxic, tasteless and chemically stable.


Various types of silica gels have different microporous structures due to their 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, chemical stability, and high mechanical strength. Silica gel is classified according to its pore size: macroporous silica gel, coarse pore silica gel, B-type silica gel, fine pore silica gel, and the like.
