Information @ a Glance


  • Silicones are largely inert compounds with heat-resistant, nonstick, and rubber like, frequently used in cookware, medical applications, sealants, lubricants, and insulation.
  • Silicones are synthesized from chlorosilanes, tetraethoxysilane, and related compounds.
  • Silicones are synthetic polymers of dimetylpolysiloxane manufactured in a variety of physical forms ranging from a thin, watery liquid to hard plastic.
  • It is colorless and has a centristoke value of 200 , allowing it to pass through a narrow-gauge needle.
  • Silicone rubber offers good resistance to extreme temperatures, being able to operate normally from -55°C to +300°C.


  • Dow Corning’s silicone-based products and technology are used for many applications, including pulping, coatings and recycling, with a focus on improving end product performance as well as processing, helping to lower costs and increase productivity.
  • Structural silicone glazing application promotes optimum sound and heat insulation.
  • The application of Silicone, particularly the gel form, is used in bandages and dressings, in breast implants and a variety of other medical uses.
  • Silicone, particularly the gel form, is used in bandages and dressings, in breast implants and a variety of other medical uses.
  • Silicone rubber received attention as an alternative to polyvinyltoluene in applications in which the scintillator is exposed to high doses because of the increased resistance of the rubber to the formation of blue absorbing color centers.
  • Applications of the new gel in power electronic devices include forming high-density, multi-layer interconnects capable of withstanding high temperatures and high rates of acceleration.


  • Silicone elastomers are typically molded by three main methods: liquid injection molding (LIM), transfer molding, or compression molding.
  • The LIM process, often chosen for high-volume applications, employs lower pressures and higher temperatures than the other molding methods—250 to 2000 psi injection pressure and temperatures of 245° to 485°F.
  • Method for preparing silicones involves reacting a chlorosilane with water. This produces a hydroxyl intermediate, which condenses to form a polymer-type structure.
  • Preparation of silicone elastomers requires the formation of high molecular weight (generally greater than 500000g/mol). To produce these types of materials requires di-functional precursors, which form linear polymer structures.


  • Silicone gel, is designed to meet the needs of the growing number of automotive electronics manufacturers who are adopting hybrid circuit designs that must be sealed and protected from harsh, under-the-hood conditions.
  • According to forecasts of the experts, one expects that subsequent growth of technical silicone production will be on average by 6% per year during the forthcoming five years.
  • China was the main producer of technical silicone and ferrosilicone.
  • According to the forecasts of European Photovoltaic Association (EPIA), average growth rate of photovoltaic elements market will come to 30% till 2020 and to 15% per year during the period from 2020 to 2040.
  • The main exporters of the product were Brasilia, China, USA and Norway, which together occupied more than 75% of the common global market.
