Silicone physical structure

Structure

Silicone materials have a unique structure:

(1) 1Adequate methyl groups on Si atoms shield the high-energy polysiloxane backbone;

(2) (2) C-H non-polarity, so that the interaction between molecules is very weak;

(3) 3Si-O bond length is longer, Si-O-Si bond bond angle.

(4) 4The Si-O bond is a covalent bond with a 50% ionic bond (the covalent bond has a directionality and the ion bond has no directionality).
