PolydimethylsiloxanNetzwerke

Polydimethylsiloxane, often abbreviated as PDMS, is a silicone polymer with the chemical formula [(CH3)2SiO]n. It is the most common type of silicone fluid. PDMS is known for its inertness, flexibility, and stability over a wide range of temperatures. It is widely used in various applications due to its unique properties.

One of the key characteristics of PDMS is its non-polar nature, which makes it resistant to oxidation and degradation. This also contributes to its water-repellent (hydrophobic) properties. PDMS is also characterized by its low surface tension, meaning it spreads easily over surfaces. Its viscosity can vary significantly, from a thin liquid to a semi-solid gel, depending on the molecular weight and degree of cross-linking.

In terms of applications, PDMS is found in a multitude of products. It is a common ingredient in lubricants, sealants, and adhesives. It is also used in cosmetics and personal care products, such as shampoos, conditioners, and lotions, for its smoothing and conditioning effects. In the medical field, PDMS is employed in medical devices, prosthetics, and as a component in contact lens solutions. Its biocompatibility makes it suitable for these sensitive uses. Furthermore, PDMS is utilized in the food industry as a defoaming agent and in various industrial processes.
