For many people, the silicone rubber are often difficult to distinguish, even equated, in general, can be divided into two categories of silicone and inorganic silica silica gel according to their nature and components.
Inorganic silica is a highly active adsorbent material, usually by reaction with the sodium silicate and sulfuric acid, and after aging, acid bulbs series of post-treatment process such as the configuration diagram on silica gel obtained.
The Silicone case of amorphous material, its chemical formula 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 silica because of their different manufacturing methods and the formation of different pore structure. The silicone chemical components and physical structure, it has many of the characteristics of other similar materials is difficult to replace: high adsorption properties, good thermal stability, chemical stability, high mechanical strength.
The silicone is an organic silicon compound, 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, 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 .
Silica gel is a silicone rubber (Q), belonging to the liquid rubber of one-component RTV. Once exposed in the air, wherein the silane monomer condensed to form a network structure, the crosslinking system, can not be melted and dissolved, resilient, into a rubbery state, while the adhesive object. Its thermal conductivity is slightly higher than the average rubber Once cured, it is difficult to separate the bonded objects.
The rubbery high elastic polymer compound. Including the uncured sulfide varieties. Can be divided into two categories of natural rubber (NR) and synthetic rubber. Natural rubber by rubber plants obtained latex by processing. Synthetic rubber monomer polymerization or polycondensation obtained. Uncured rubber is commonly known as raw rubber, raw rubber. Called vulcanized rubber vulcanized rubber or rubber, commonly known as cooked. Widely used in the manufacture of tires, hoses, tapes, insulating materials, rubber shoes and other rubber products, Such as silicone gloves,silicone lid, silicone cake mold, silicone kitchen tools,silicone ice cube tray.
