Application

Octamethylcyclotetrasiloxane is primarily used as a precursor in the production of polydimethylsiloxanes (PDMS) and other silicone-based materials. It finds applications in cosmetics, where it acts as an emollient and carrier fluid due to its smooth texture and volatility. Additionally, it is employed in industrial lubricants, dielectric fluids, and as a solvent in chemical synthesis. Its thermal stability also makes it suitable for high-temperature applications in coatings and elastomers.
