Siloksaaneja

Siloksaaneja are a class of organosilicon compounds characterized by a silicon-oxygen backbone. This backbone consists of alternating silicon and oxygen atoms, with organic groups attached to the silicon atoms. The general formula for linear siloxanes is [R2SiO]n, where R represents an organic group such as methyl, ethyl, or phenyl, and n is the number of repeating units. Cyclic siloxanes have the formula [R2SiO]n, where n is typically 3 or more.

The properties of siloxanes are highly dependent on the nature of the organic groups attached to the silicon atoms and the length and structure of the siloxane chain. They exhibit a wide range of physical characteristics, from volatile liquids to viscous oils, greases, and solid polymers. A key feature of siloxanes is their thermal stability, resistance to oxidation, and inertness. They also possess low surface tension, good dielectric properties, and hydrophobicity.

Siloxanes find extensive use in various industries. They are employed as lubricants, sealants, adhesives, and as components in cosmetics and personal care products due to their smooth feel and water-repellent nature. In the medical field, their biocompatibility makes them suitable for implants and drug delivery systems. Silicone rubbers, which are cross-linked siloxane polymers, are used in a multitude of applications ranging from cookware to electrical insulation. The versatility and unique properties of siloxanes have made them indispensable materials in modern technology and consumer goods.
