Polydimethylsiloxanöl

Polydimethylsiloxanöl, often abbreviated as PDMS-OH or simply silicone oil with hydroxyl end groups, is a type of silicone polymer. It is characterized by a silicon-oxygen backbone with methyl groups attached to the silicon atoms. The "öl" suffix indicates it is an oil, and the "-OH" signifies the presence of hydroxyl functional groups at the ends of the polymer chains.

These hydroxyl groups make polydimethylsiloxanöl more reactive than its non-functionalized counterpart, polydimethylsiloxane. This reactivity allows it to be used as a building block in the synthesis of other silicone-based materials, such as silicone elastomers and resins. It can undergo cross-linking reactions to form three-dimensional networks, which impart properties like flexibility, thermal stability, and water repellency to the final product.

Polydimethylsiloxanöl finds applications in various industries. It can be used as a surface modifier to enhance the adhesion or release properties of materials. In personal care products, it might function as an emollient or conditioner. Its ability to form stable films also makes it useful in coatings and sealants. The specific properties and applications depend on the molecular weight and degree of functionalization of the polymer.
