Classification and Properties of Silicone Products

Generally, according to their nature and components, silicone rubber can be divided into two categories of organic silicone and inorganic silicone. And it can be divided into extrusion silicone and molded silicone according to its component shape.

Inorganic Silicone

Inorganic silicone is a highly active adsorption material, usually a reaction with sodium silicate and sulfuric acid, and aging, acid bulbs obtained a series of post-processing. The silicone case is amorphous material, and its chemical formula is mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silicone, because of their different manufacturing methods, form different pore structures. The silicone chemical components and physical structure, and it has many characteristics of other similar materials difficult to replace: high adsorption properties, good thermal stability, chemical stability, high mechanical strength. Because of the superior performance characteristics of the inorganic silicone, it is used in various industries, such as the common colorful kids slap watches are made of inorganic silica.

Organic Silicone

The organic silicone is an organic silicon compound, refers to those containing a Si-C bond, and at least one organic group is directly connected to a silicon atom in the compound, it is customary also often to the organic group and the silicon through oxygen, sulfur, nitrogen, etc. atoms connected to the compound is also used as organic silicon compound. Wherein the silicon-oxygen bond (-Si-O-Si-) as a skeleton consisting of a polysiloxane, which is more than 90% of the total amount of the organic silicon compound (s) in the number of the most studied deepest, one of the most widely used class approximately. Extrusion silicone is more common, such as household electric cooker seals, called the rice cooker silicone ring. There are many other silicone products made of silicone.

Security Performance of Silicone

The main ingredient of silicone is silica, chemically stable, and does not burn. Silica gel is an amorphous silica, should control the workshop dust content of not more than 10 mg / cubic meter, the need to strengthen the exhaust, wear masks when operating. Silicone has a strong adsorption capacity, human skin can produce dry and, therefore, the operation should wear overalls. If the silicone comes into the eyes need plenty of water and seek medical treatment as soon as possible. Blue silicone, because it contains a small amount of cobalt chloride, toxic, should be avoided and food contact and inhalation of the mouth, such as the occurrence of poisoning should immediately seek medical treatment. The silica during use due to the adsorption of water vapor in the medium or other organic substances, the adsorption capacity decreased, and it can be reused after regeneration.
