Each port is tailor-made to ensure 100% kiss and does not affect the function of the port. When the port is not in use, it prevents dust and moisture from entering, prevents oxidation, and indirectly extends the service life...
(Some friends often ask if this dust plug will affect the heat dissipation. Here is a friendly reminder that the heat dissipation of MACBOOK is concentrated in the keyboard area, so there is no need to worry about this problem at all!*)
→Material Description:
Silica gel(Silica gel; Silica)Alias: Silicone rubber is a kind of highly active adsorption material, it 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. Various types of silica gel 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.
