Silicone Oil or Siloxane
Silicone oil refers to any hydrophobic linear synthetic polymers consisting of repetitive silicon-oxygen (Si-O) units and organic side chains. One of the simplest and most widely used silicone oil is polydimethylsiloxane (PDMS).
Properties of silicone oils (PDMS)
Silicone oils and polydimethylsiloxane are colorless liquid substances existing in various viscosity in different applications. They have interesting properties such as high thermal stability, electrical insulation, water repulsion, anti-adhesive characteristics, biocompatibility, and good mechanical properties that make them useful in different industries. Silicone oils possess physiological inertia, good chemical stability, are odorless, non-toxic, and non-irritating to the skin. The viscosity range of silicone oils is 1 to 1000000 centistokes (cSt). Increasing the molecular weight of silicone oil leads to longer polymer chains and higher viscosity. In the Sinoxe company, there are dimethylsiloxanes with two different viscosities: 350cSt and 1000cSt.
Application of silicone oils in different industries
Silicone oils are widely used as anti-foam agents, lubricants, and heat transfer fluids in different industries.
Silicone oil in medicine
In the medical field, silicone oil is used as a substitute for vitreous fluid to treat difficult cases of retinal detachment.
