Product detail:
Organic silicon compounds, containing Si-C bond, and at least an organic base is directly connected with the silicon atoms of compounds, often customary to oxygen, sulfur, nitrogen and other organic-based compounds of silicon atoms connectedas organic silicon compounds. Among them, the silicon-oxygen bond (-Si-O-Si-) for the skeleton composed of polysiloxane is the largest number of organic silicon compounds, the deepest, the most widely used class, accounting for more than 90% of the total amount of .
The structure of the silicone material has a unique structure:
(1) Si atoms sufficient methyl polysiloxane main chain of high-energy shielding;
(2) CH Promise of the intermolecular interaction is very weak;
(3) Si-O bond length is longer, the Si-O-Si bond angle;
(4) Si-O bond is 50% ionic bond characteristics of covalent bonds (covalent bond is directional, ionic bond non-directional).
