- Silicones are largely inert
compounds with heat-resistant, nonstick, and rubber like, frequently
used in cookware, medical applications, sealants, lubricants, and
- 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
- 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
- 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
- Applications of the new gel in
power electronic devices include forming high-density, multi-layer
interconnects capable of withstanding high temperatures and high rates
- 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
- 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
- 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.
