Generally speaking, the medical silicone tube can be divided into two categories: Organic medical silicone tube and inorganic silicone tube.
The inorganic medical silicone rubber tube is a kind of highly active adsorption material, which is usually reacted with sodium silicate and sulfuric acid. Silica gel is a kind of amorphous material, its chemical formula is mSiO2.nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, in addition to alkali, hydrofluoric acid does not react with any material. Various types of silica gel due to their different methods of production and the formation of different microporous structure. Silica gel chemical composition and physical structure, determines the characteristics of it has many other similar materials to replace the high adsorption properties, good thermal stability, chemical stability, high mechanical strength, do household desiccants, humidity regulator, deodorants; hydrocarbon industry as decoloring agent, catalyst carrier, adsorption agent separation and purification; with fine chemical agent, beer stabilizer, paint thickener, toothpaste friction agent, flatting agent etc.
Silicone is a silicone compound, means containing Si-C bond, and at least one organic compound base is directly connected with the silicon atoms, habits are often those connected with oxygen, sulfur, nitrogen and other organic radicals and silicon atoms compounds as organosilicon compounds. Among them, the silicon oxygen bond (-Si-O-Si-) polysiloxane skeleton composed of organosilicon compounds, is the largest number in a class, most widely and deeply studied, accounting for more than 90% of the total amount.
Extrusion of silica gel is more common, such as household electric cooker on the sealing ring, called the rice cooker silicone sealing ring.
Molded silicone is a bit more complicated, irregular shape, including silicone bowl, silica gel, silicone cake mold, and so on.
