What is the composition of silicone?
The basic material of silicone chemistry is quartz, itisie silica or silicon dioxide, SiO2. The name “silicon” comes from the Latin silex, silicis: pebble. Silicon exists in nature only in a combined form, mainly as silicon dioxide and silicates.
Its excellent properties insulating, also appreciated in electronics, are thus expressed independently of the temperature. If a fire breaks out, the silicone does not emit any aggressive or corrosive gases, and forms, moreover, insulating silica ashes.
They must be brought to the recycling center, if possible in their original packaging or specifying their nature on their new container. They are then taken care of by EcoDDS to be recovered in terms of energy (heating, electricity), recycled or disposed of under conditions that respect the environment.
But silicone is more resistant to heat, chemical attack, fungal attack, UV and ozone than normal rubber.
The first operation, in the preparation of a silicone, is the manufacture of the silicon. The silicon dioxide SiO 2 is reduced to the state of silicon by heating in an electric furnace, in the presence of carbon. Silicon is in the form of a solid body, black gray, having a metallic reflection.
The most common type is linear polydimethylsiloxane (PDMS). The second largest group of silicone materials are silicone resins, formed by branched or cage-shaped oligosiloxanes. The word silicone is epicene. So we say:
The history of silicones results from the combination of university and industrial research. The basic material of silicone chemistry is quartz, ie silica or silicon dioxide, SiO 2. The name “silicon” comes from the Latin flint, silicis: pebble.
