Silicones form a group of synthetic polymers in which silicon atoms are linked via oxygen atoms to form molecular chains and / or network-like. The remaining free valence electrons of silicon are saturated by hydrocarbon residues (mostly methyl groups). Due to the chemical composition of these polymers, silicone compounds differ from traditional synthetic rubbers in that they are characterized by high performance.
They are highly resistant to hot air (+ 200C to peaks up to + 300C for a limited time with special base polymers) and retain their elasticity even at very low temperatures. After vulcanization, these products are resistant to oxygen, ozone, weather and UV radiation.
The vulcanized articles, produced from specially developed silicone mixtures, are physiologically inert, odorless, tasteless and can in some cases be used to produce articles that are used in the food and medical sectors. Other typical areas of application are the automotive and aerospace industries, the clothing and sports industries, and the electrical insulation of lines and cables.
