What is silicone?

1. What Silicone Is (Chemically)

  • Base element: Silicon (Si), a metalloid element from the periodic table.
  • Polymer structure: Silicone is made by combining silicon with oxygen and organic groups (like methyl or phenyl).
  • General formula: (R₂SiO)n, where R represents organic side groups.

This creates a siloxane backbone (Si–O–Si) — flexible, stable, and resistant to heat, UV light, and moisture.


🧱 2. Common Forms of Silicone

Silicone can be formulated into different materials depending on additives and processing:
