What is silicone?
Silicone is a type of polymer whose backbone consists of alternating silicon and oxygen atoms, with various organic groups attached to the silicon atoms. It includes silicone resins, silicone rubber, and silicone oils.
What is silica gel?
Silica gel is a highly active adsorbent material mainly composed of silicon dioxide, with the chemical formula mSiO2·nH2O. It is insoluble in water and any solvent and has stable chemical properties.
Difference between silicone and silica gel:
Silicone is produced by reacting hydrated silica and methylchlorosilane through heating, while silica gel is mainly composed of silicon and oxygen and is not an organic material. This is because silica gel cannot be extracted from carbon-containing compounds but from silicates. Silicone has high temperature stability, chemical inertness, and flame retardancy, while silica gel is chemically stable and resistant to corrosion by chemicals, making it a material with significant application and research value.
Silicone Application Areas ：
Construction Industry: It possesses excellent waterproof, weather-resistant, and corrosion-resistant properties, ensuring the long-term durability and reliability of buildings.
Electronics Industry: Its good insulation and high-temperature resistance properties make it widely used in the manufacturing of electronic components and circuit board assembly.
Medical Field: Silicone's good biocompatibility and stability make it widely used in medical devices, medical supplies, and pharmaceutical production.
Automotive Industry: Used in the manufacturing of automotive seals, sound insulation materials, and coatings, providing reliable assurance for automotive manufacturing and maintenance.
Silica Gel Application Areas:
Daily Life: Silica gel's excellent adhesion and water resistance make it widely used in sealing and bonding applications for household goods, bathroom fixtures, glass curtain walls, etc.
Automotive Industry: In automotive manufacturing and maintenance, silica gel provides excellent sealing and bonding, ensuring vehicle reliability and performance.
Electronics Industry: Silica gel's insulation and high-temperature resistance make it an essential material in the manufacturing of electronic components and circuit boards.
In summary, although both silica gel and silicone contain silicon, their chemical structures and physical properties differ significantly. Therefore, different preparation processes and compositions determine their physical properties and applications in various industrial, daily life, and technological fields.
