polydimethylsiloksenit

Polydimethylsiloxanes, often abbreviated as PDMS, are a group of polymers with the chemical formula [-(CH3)2SiO-]n. They are the most common type of silicone fluid and are characterized by their high flexibility, thermal stability, and inertness. PDMS is a clear, odorless, and non-toxic substance. Its unique properties stem from the silicon-oxygen backbone, which is very stable, and the methyl groups attached to the silicon atoms, which provide hydrophobicity and flexibility. The chain length, represented by 'n', can vary significantly, influencing the viscosity and physical state of the PDMS, ranging from low-viscosity liquids to rubbery solids.

PDMS finds widespread application across numerous industries. In the personal care sector, it is a common ingredient in shampoos, conditioners, skin creams, and cosmetics due to its emollient and conditioning properties, providing a smooth feel and improving spreadability. The medical field utilizes PDMS in devices like catheters, tubing, and prosthetics because of its biocompatibility and resistance to degradation. In the industrial realm, PDMS serves as a lubricant, a component in sealants and adhesives, a defoaming agent in food processing and manufacturing, and a dielectric fluid in electrical applications. Its resistance to oxidation and UV radiation also makes it suitable for outdoor applications. The versatility and beneficial properties of polydimethylsiloxanes have cemented their importance in modern materials science and technology.
