polydimetylsiloksan

Polydimethylsiloxane, often abbreviated as PDMS, is a synthetic silicone polymer with a wide range of applications due to its unique properties. It is characterized by a backbone of silicon-oxygen atoms with methyl groups attached to each silicon atom. This chemical structure imparts to PDMS its notable features such as flexibility, chemical inertness, thermal stability, low surface tension, and biocompatibility.

PDMS exists in various forms, from viscous liquids to rubbery solids, depending on its molecular weight and cross-linking. Its low viscosity at room temperature makes it an excellent lubricant and antifoaming agent. The inert nature of PDMS means it does not readily react with other chemicals, making it suitable for use in sealants, adhesives, and coatings where resistance to environmental factors is crucial.

The biocompatibility of polydimethylsiloxane allows for its use in medical devices, personal care products, and food-grade applications. It is commonly found in contact lenses, prosthetics, shampoos, conditioners, and even in some food processing as an antifoaming agent. Its ability to form flexible films and its resistance to degradation under various conditions further contribute to its widespread adoption across numerous industries.
