The first time I heard the term platinum silicone, I also wondered if there is really metal in it (of course it can't be platinum). But after a preliminary understanding, I have to come out to refute a rumor: in theory, there is no platinum in platinum silicone!

There are many different forms and synthesis methods of silica gel today. Platinum "Platinum" in platinum silica gel is a catalyst, a substance used to speed up the synthesis of silica gel. In terms of chemical properties, platinum silica gel is more stable and will not decompose during heating like inferior silica gel. But it does not rule out that some platinum will be mixed into the silica gel during the processing. But it doesn't matter, precious metals such as platinum and gold will not react with the human body because of their strong "inertness", and platinum silica gel contains only a small amount of metal, even if it enters the human body, it will be excreted with metabolism (listen It is said that in Japan and Taiwan, some people really add gold leaf to their dishes to eat, yes, it is the kind made of gold). 

Platinum silica gel is a kind of silica gel. It is a polymer of "silicon" and "oxygen" - silicone resin (also called silicone, silicon licang. It is called Silicone in English, and some also call it silicone), although the texture is soft It is elastic, but in composition it is more like glass (the main component of glass is silica). However, it should be noted that the translation definition of "silica gel" in China is a confusing account: many people confuse the silica gel used as a mold with the silica gel used as a desiccant (Silicone rubber in English). Silicone and Silicone rubber can both be called "silica gel" in Chinese, but they are substances with completely different properties and uses.
