Silicone knowledge 
Silicone alias: Silicic acid rubber, a highly active adsorbent material, is an amorphous material. The main component of silica gel is silica (so called silica gel), which is chemically stable and does not burn. Chemical formula xSiO2·yH2O, transparent or milky white granular solid, has an open porous structure, strong adsorption, and can adsorb a variety of substances.  

The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
According to its properties and composition, silica gel can be divided into two major categories: organic silica gel and inorganic silica gel. Divided into extruded silica gel and molded silica gel according to its composition.
Inorganic silica gel is a highly active adsorbent material, usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gels have different microporous structures due to their different manufacturing methods. Organosilicone is an organosilicon compound, which refers to a compound containing Si-C bonds and at least one organic group directly connected to a silicon atom. It is customary to use organic groups and silicon through oxygen, sulfur, nitrogen, etc. Atom-linked compounds are also considered as organosilicon compounds. Among them, polysiloxanes composed of silicon-oxygen bonds (-Si-O-Si-) are the most widely studied and most widely used organosilicon compounds, accounting for more than 90% of the total dosage. .
Extrusion of silica gel is more common, such as the sealing ring on a rice cooker for household use, which is called a rice cooker silicone seal ring. Molded silicone is more complicated and irregular in shape, including silicone bowls, silicone ice trays, silicone cake molds, and so on.
How is platinum silica made?
Platinum silica gel is a kind of silica gel, which is a silica gel obtained by mixing and vulcanizing a two-component platinum vulcanizing agent with high transparent gas phase silica gel. The platinum vulcanizing agent is also called platinum water. The vulcanization principle is that in the presence of the catalyst platinum Pt, the hydrosilane oil and the vinyl double bond undergo a hydrosilylation reaction to achieve the purpose of cross-linking vulcanization. The product is used to play a role in vulcanization. (It is too expensive, use 180 yuan 1 gram of platinum as a catalyst. ☺) Since the hydrosilylation reaction is easy to react in the presence of Pt catalyst, the platinum vulcanizing agent is divided into component A (TNA). -00PS/J) and B (TNB-00PS/J) components. Platinum is so expensive, why should we add it to the silica gel? Platinum is a catalyst used to accelerate the solidification of food grade silica gel, making platinum silica gel more chemically stable. No matter whether it is high temperature or low temperature, strong acid or strong alkali, it will not emit any harmful substances. Inferior silica gel decomposes on heating. Because precious metals such as platinum have a strong "inertness", they will not react with the human body. Even if they enter the human body, they will be excreted with metabolism. I heard that some people in Japan and Taiwan still have gold foil in their dishes. Yes, that is what gold does.) Compared with other vulcanizing agents, platinum vulcanization has better environmental safety. It has no odor after vulcanization with silicone tube, high hygienic and environmental protection grade, high transparency of silicone tube, and greatly improved tensile strength and resilience of the product. Widely used in medical supplies, baby products, tableware supplies and other industries.

in conclusion:
Ordinary silica gel is made of ordinary translucent silica gel and traditional ordinary vulcanization. The material performance is more common. The product is non-toxic, odorless and has excellent performance in all aspects. It is sensitive to light, oxygen, heat and other environment. Yellow hair will occur in long-term use. Dark odor. Low cost, used in the production of common products, mainly used in industrial, construction, electronics and other fields, the performance will gradually age under long-term use. The raw material of platinum silica gel is made by mixing high-transparent gas phase silica gel with two-component platinum vulcanizing agent. It will not turn yellow and deform after long-term use, and has more outstanding safety performance, high effic
