The difference and classification between silicone and silicone rubber

The application of silicone has been very extensive, but some people may not be very familiar with the understanding and distinction between silicone and silicone rubber. Today, this article will elaborate on the differences and classifications between silicone and silicone rubber. At present, the concept of "silicone" is not standardized, as there is no clear national definition of its term. When we hear the word 'silicone', we must understand whether it is silica or silicone containing synthetic rubber, or ultimately whether it is inorganic silicone or organic silicone.

There are several related terms for the term "silicone": silicone rubber, silicone rubber, and silicone. The relationship between silicone rubber and silicone is different from silicone rubber and includes silicone rubber. Silicone rubber is an organic "silicone" within "silicone". "Silicone" is a term used by Hong Kong and Taiwan. In Chinese Mainland, it is called "silica gel". Silicone and Silikon are transliterations of English silicone. We usually say that it means "silica gel".

In summary, silica gel can be divided into two categories based on its properties and components: organic silica gel and inorganic silica gel.

Inorganic silica gel is a highly active adsorption material, usually prepared by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid foaming. Silicone is an amorphous substance with the chemical formula mSiO2. nH2O. Insoluble in water and any solvent, non-toxic and odorless, chemically stable, and does not react with any substance except strong bases and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods.

The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. Due to its chemical properties, it is used to make many types of silicone products, such as silicone sealing rings, silicone sealing strips, silicone kitchen utensils, and so on.
