Is The Silicone Cup Lid Toxic After High Temperature?

No, the silicone itself is non-toxic.

Silicone is a high pressure resistant and environmentally friendly material. It can be used at temperatures ranging from -60 ° C to 250 ° C without any chemical reaction. Moreover, it is odorless and does not decompose colored objects. It is a harmless and healthy material. The chemical is relatively stable and does not react chemically at temperatures of 200 degrees. In fact, in Europe and the United States, people used silicone products, silicone tableware and other products a few years ago. There is a lot of experience in technology. The World Health Organization is more concerned about the quality of our food materials, and cares about the production requirements of silicone products. If it is not up to standard, it cannot be produced. Therefore, everyone can use it with confidence.

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

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, is insoluble in water and any solvent, and is non-toxic. It is tasteless and chemically stable.

Various types of silicone have different microporous structures due to their different manufacturing methods.

The chemical composition and physical structure of silicone 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. Silicone is classified according to its pore size: macroporous silicone, coarse pore silicone, B-type silicone, fine pore silicone, and the like.
