What are Siloxanes?

Siloxanes are a family of chemical compounds composed of silicon and oxygen atoms. Silicon dioxide (SiO₂) is the fundamental component of sand. Siloxanes are found in nature in minerals like sand, quartz, and opal. They can also be synthetically produced.

Properties of Siloxanes

  • Siloxanes are colorless, odorless, and tasteless liquids or solids.
  • They are resistant to water.
  • They are heat-resistant.
  • They have insulating properties.
  • They are resistant to chemicals.
  • They are biologically compatible.

Applications of Siloxanes

  • Construction Materials: Used in waterproofing materials, adhesives, sealants, and paints.
  • Personal Care Products: Used in cosmetics, shampoos, soaps, and deodorants.
  • Medicine: Used in medical implants, prosthetics, and contact lenses.
  • Textiles: Used to produce water-resistant and stain-resistant fabrics.
  • Automotive: Used in engine oils, greases, and coolants.
  • Electronics: Used as insulation and coating materials.

RS-PDMS 12,500 cSt

RS-PDMS 12,500 cSt is a type of silicone liquid known as polydimethylsiloxane (PDMS) with a high viscosity of 12,500 centistokes (cSt). It is a clear, colorless, odorless, and non-toxic liquid. Its high viscosity makes it thick and resistant to flow.

Key Properties

  • High Viscosity: As mentioned, it has a high viscosity of 12,500 cSt, making it thick and resistant to flow.
  • Wide Temperature Range: It has a wide operating temperature range from -50°C to +200°C, making it suitable for various applications where temperature fluctuations are a concern.
  • Chemical Stability: Chemically inert and resistant to many chemicals, including acids, bases, and oils. This makes it suitable for applications that may come into contact with harsh chemicals.
  • Electrical Insulation: A good electrical insulator, making it useful in electrical applications.
  • Water Repellency: Water-repellent, making it suitable for applications where water resistance is desired.
  • Biocompatibility: Generally considered biocompatible, meaning it is compatible with living tissue and can be used in medical applications.

Applications

  • Lubrication: Used as a lubricant in various applications such as shock absorbers, precision device lubricants, and heat transfer fluids due to its high viscosity and good thermal stability.
  • Antifoaming Agent: Can be used as an antifoaming agent in various industrial processes such as food processing and chemical manufacturing.
  • Damping Agent: Can be used as a damping agent to reduce vibration and noise in various applications such as automotive parts and electronic devices.
  • Medical Devices: Used in various medical devices such as catheters, implants, and prosthetics due to its biocompatibility.
  • Cosmetics: Used in some cosmetic products such as skin creams and hair care products due to its lubricating and water-repellent properties.
