The difference between silicone and silicone rubber
According to some chemical books on the name of "silica gel" should be a condensate of silica, the molecular formula is mSiO2 • H2O. The "silica gel" is a highly active adsorbent material, is an amorphous material, insoluble in water and any solvent, non-toxic and tasteless, chemical stability, in addition to alkali, hydrofluoric acid does not react with any substance. And we often say that the rhinoplasty, breast filled with silica gel is the kind of silica gel.
But in the mold industry, we refer to the "silica gel" is usually not referred to above the silica hydrate silica gel. Mold industry, silicone is usually a kind of polysiloxane, simply put, the mold industry, "silicone" is a synthetic rubber, because it contains silicon atoms so called silicone rubber, so was referred to as "silicone".
Mold industry, "silicone" a wide range of different uses. As for the performance of the product according to the different raw materials have a great gap, but in general this "silicone" (indeed silicone rubber) in the future showing a trend instead of rubber.
We often put in the "silicone" is often not simply refers to the silica condensate, nor is it said that the mold industry above the silicified synthetic rubber. But the above two types of products are called "silicone". At this time we again "silicone" is divided into organic silica gel and inorganic silica gel. Inorganic silica gel is what we mentioned as the first "silica gel" - silica hydrate.
Mold industry silicon-containing synthetic rubber because it contains hydrocarbons is called organic silicone. In some places talking about "silicone rubber" when it will be defined as "between the organic matter and inorganic matter", but more manufacturers of silicone rubber or boast is the production of silicone.
From the above three cases, the concept of "silica gel" is very confusing, but unfortunately, to the present there is no state expressly called the law.
When we hear the word "silica gel" when we must understand whether it is silica or silicon-containing synthetic rubber, or in the end is inorganic silica gel or organic silicone.
It is necessary to mention here and the "silicone" called the law of several words: silicone rubber, silicone, silicone
Silicone rubber and the relationship between silica gel has been said above, the difference between silicone and silicone rubber, silicone rubber is "silicone" inside the organic "silicone". "Silicone" is the name of Hong Kong and Taiwan, in the mainland called "silicone", then in accordance with the mainland "silica gel" chaos called, silicone is also a mess of the term. Silicone is transliteration of silicone, we usually say that he is "silicone".
