I will explain about "silicone," which is surprisingly not well-known despite seeming familiar!
"Silicone" generally refers to an organic silicon polymer material that has a skeleton formed by the bonding of silicon and oxygen (siloxane bond / -Si-O-Si-) with organic groups (methyl groups) attached to the side chains of silicon atoms. It is chemically inert, has a small change in viscosity with temperature, and is characterized by low surface tension. Compared to the C-C bonds of typical organic compounds, the Si-O bond energy is higher, and the internal rotational energy is nearly 0 KJ/mol, making the rotation of the main chain bonds easy. It possesses properties such as flexibility, heat resistance, cold resistance, low surface tension, and gas permeability. Organic silicon resins, polyorganosiloxanes, and polysiloxanes may also be collectively referred to.

basic information
**Chemical Properties of Dimethylsilicone** - The bond energy of Si-O-Si is large, making it strong against heat. - The internal rotational energy of the Si-O-Si bond is nearly 0 KJ/mol, making it less susceptible to temperature effects. - The ionic nature of the Si-O-Si bond is high, allowing for changes in bond angles with relatively small forces. - The bond spacing of Si-C is large, making it resistant to decomposition from heat and oxidation. - It is less affected by intermolecular forces and does not crystallize at low temperatures. *For more details, please feel free to contact us.*
