What are the similarities between the airliner and a sponge for washing dishes, cars, and contact lenses, telephone and the space station? All of these mechanisms, things and devices contain silicone.
It can be a liquid such as water or as hard as glass - or simply polyorganosiloxane silicone, in the opinion of many scientific experts, is the main material of the XXI century, radically changed our lives. Any compound having in the silicon can be attributed to the silicone. Actually from the English name Silicon and takes the name of the entire group of silicone materials.
Silicones are of paramount importance in today's industry. If you look around, almost no matter what the subject of the modern world we have not seen each of them incorporates a silicone.
Oxygen and silicon are the most abundant elements on Earth. Quartz, rock crystal and regular river sand - all based on silicon, natural reserves are large and constantly replenished, and hence resource for silicones is practically inexhaustible.
silicone raw material
Of such silicone "cake" can be made by curing the silicone material is any of the properties.
To understand why this stuff is so popular, it is necessary to consider it at the deepest molecular level.
To the main chain silicon-oxygen-silicon (Si-O-Si) can be connected almost all the elements in each sequence. This may be a non-linear structure and the molecular lattice. Ability to organize a lot of different options of the chemical bond - the unusual properties of silicone.
Silicone materials appear through the combination of seemingly incongruous elements, so they have special properties. It silicones have a very high and very good range of temperatures - from -120 to +300 degrees. In this case, -60 to +200 runs any, even the most common form of this material.
The sharp temperature drop between the marks - the extreme conditions for many materials. But not for silicones, which is very easy to check. The boiling point of water 100 degrees and instantly drop to zero (since the formation of ice) does not leave a trace of silicone samples. This ability has made them indispensable silicones in aviation, learn more about silicone gaskets
The plane is very obvious example. When he was flying at an altitude of 10 thousand meters, where the temperature is -60 degrees, and sits down at the airport, where +30-50 degrees, the silicone components do not react to such extreme temperatures and it can withstand them with ease and properly seals all what you need.
