What is calcium silicate insulation used for?
What is calcium silicate insulation used for?
Calcium silicate (sometimes referred to as “calsil”) is used to insulate high temperature pipes and equipment and to achieve fire endurance. It is manufactured and sold in three different forms: preformed block; preformed pipe; and board.
What type of insulation is calcium silicate?
Calcium silicate insulation is inorganic, noncombustible, asbestos-free and meets or exceeds the physical and thermal property requirements of ASTM C533, Type 1.
What is Calsil pipe insulation?
Calcium Silicate Pipe and Block Insulation (Calsil insulation) is a molded, high temperature, abuse-resistant pipe and block insulation with exceptional structural strength, composed of hydrous calcium silicate for use on systems operating up to 1200°F (649°C).
Is calcium silicate harmful?
Calcium silicate causes physical irritation when in contact with the eyes, skin, or upper respiratory tract of exposed workers.
What is the common name for calcium silicate?
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2. It is also referred to by the shortened trade name Cal-Sil or Calsil. It occurs naturally as the mineral larnite.
What is calcium silicate insulation made of?
Calcium silicate insulation is manufactured from amorphous silica, lime, reinforcing fibers and other additives that are mixed with water in a batch mixing tank to form a slurry. This slurry is pumped to a pre-heater where it is heated to boiling and quickly poured into molds.
What is Pyrogel insulation?
Pyrogel XTE is a flexible, high-performance, aerogel blanket insulation designed for use in industrial applications. Pyrogel XTE is engineered to deliver superior thermal performance while offering excellent protection against corrosion under insulation (CUI).
Is calcium silicate a carcinogen?
In the available data on subacute toxicity, genotoxicity and developmental toxicity studies, no adverse effects were reported for silicates and talc. From the only chronic toxicity study (with calcium silicate) available, there was no indication for carcinogenicity.
How is calcium silicate insulation made?
Is calcium silicate the same as silica?
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2. It is also referred to by the shortened trade name Cal-Sil or Calsil. It occurs naturally as the mineral larnite….Calcium silicate.

How do you make calcium silicate insulation?
Is aerogel and Pyrogel the same thing?
Pyrogel and Cryogel (Aerogels) are flexible insulation blankets using patented nanotechnology. Aerogels are made with reinforcing fibres to deliver superior thermal performance at low and high temperature applications.
How much do aerogels cost?
At about $23,000 per pound, aerogel is currently more expensive than gold [source: NASA JPL, FAQs]!
What is calcium silicate made from?
Calcium silicate is produced from lime, hydrochloric acid, and sodium silicate. Burnt lime is treated with hydrochloric acid to produce calcium chloride. The calcium chloride solution is then treated with a clear sodium silicate once calcium silicate is precipitated out.
Is silicate and silicone the same?
Silicon links up with oxygen (which makes up 55% of the earth’s crust) to form the most common suite of minerals, called the silicates. Quartz, feldspars, olivine, micas, thomsonite, jadeite, and prehnite are all silicates. There is so much oxygen around that pure native silicon is almost never found naturally.
How long does aerogel insulation last?
The results show that for the different investigated materials, the increase in the thermal conductivity over the pristine conditions is typically below 10% for aging exposure corresponding to 20 years in typical conditions.
What company makes aerogel?
Aspen Aerogels, the world’s leading manufacturer of aerogel insulation, has filed for an initial public offering of its common stock. Aspen, which expects to trade under the stock symbol “ASPN” on the New York Stock Exchange, is looking to raise a maximum of $86.25M with this initial offering.
What are the downsides to using aerogel?
Disadvantages: Increased density (typically about one-third to one-half the density of water) Decreased clarity (from translucent to foggy to opaque) Decreased surface area (by about half)
How long does aerogel last?
Is silica toxic to humans?
Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen.
