Brief Introduction of Calcium Silicate

 calcium silicate is commonly used as high temperature insulation materials. It is white, asbestos free, rigid. Industrial grade piping and equipment insulation is often fabricated from calcium silicate. Calcium silicate competes in these realms against rock wool,perlite mixture and vermiculite bonded with sodium silicate.It is manufactured and sold in three different forms: preformed block, preformed pipe, and board.

our cal,sil is mainly exported to Korea, Japan, Thailand, some to America, Europe and Middle East.

Product Characteristics Absolutely excellent!

  1. superior insulation property (relatively flat thermal conductivity curve)

  2. refractory , having a high melting point, resistant to melting. Refractory materials are often used to line the interior of industrial furnaces.

  3. extremely high compressive strength, and high flexural strength, could withstand considerable physical abuse without loss of insulating efficiency.

  4. a Class A rating for Flame Spread/Smoke Developed, and is noncombustible (ASTM E136),

  5. “green”-asbestos free

  6. high-temperature structural integrity

  7. corrosion inhibition.

  8. a major contributor to conservation of energy

  9. good maintainance of those properties over time up to its classified temperature (superior durability)

  10. no reports of calcium silicate's being hazardous or harmful to humans


(ASTM) C533 Yes, we can!

American Society for Testing and Materials (ASTM) C533

Type I: maximum-use temperature of 1,200°F(649°C),maximum density:15 pounds per cubic foot (lbs/ft3) (240kg/m³)or 22 lbs/ft3 (352kg/m³)

Type II: 700°F (927°C)and maximum density of 22 lbs/ft3 (352kg/m³)

Both types: Compressive strength is greater than 100 pounds per square inch (psi) (688 kPa), at a 5-percent deformation.Flexural strength is greater than 50 psi (344 kPa). The maximum linear shrinkage: only 2 percent.

Both the flame spread and smoke developed index are 0 per ASTM E84.Maximum allowable mass loss values: 20%and 40% after tumbling for 10 minutes and 20 minutes, respectively, demonstrating its resistance to breakage.


Common Applications Right here, hesitate no more!

We insulate process and laboratory kilns and furnaces, thermal analytical instruments, and specialty applications, high-temperaturepipe and equipment in industrial facilities, such as oil refineries, petrochemical plants, power plants, steam distribution lines, chemical plants, refineries.

Q:Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board?
Ceramic fiber boardCeramic fiber board product categories:1260 standard ceramic fiber board sygx-264 1260 high purity ceramic fiber board sygx-3641400 zirconium ceramic fiber board sygx-564 1400 high alumina ceramic fiber fire plate sygx-464D1400 zirconium ceramic fiber fire baffle sygx-564D
Q:What is the difference between ceramic fiber board and nano ceramic fiber board?
The nano ceramic fiber board through the introduction of nanotechnology, the special production process, product performance has been greatly improved, high strength, low thermal conductivity, good heat insulation performance, energy saving effect is obvious, which improves the safety of the furnace, and in high temperature and high pressure conditions, can also play a good performance the product.
Q:Ceramic fiber plate and aluminium silicate plate are chosen as lining materials
Ceramic fiber board is of high quality ceramic fiber cotton with low slag ball content as raw material, using specific pulp and mixing equipment, ensure the cutting length and the concentration uniformity of cotton fiber, using international advanced vacuum molding technology and international advanced processing technology, the product not only has excellent mechanical strength and precise geometry the size, and maintains the excellent properties of fibrous insulation materials, can be substituted for calcium silicate board also requires tough, self-supporting and refractory insulation field.
Q:What are the specifications of the ceramic fiber board?
Ceramic fiber board density in conventional 300-350Kg/m over 350Kg/m to fand, fand fireproof plate series.
Q:What are the sound-absorbing fiber boards?
The theory on the absorption coefficient is the best sound-absorbing board sound-absorbing effect 1 (all suck, no reflections), but in reality, this material does not exist (black holes in the universe are the sound absorption coefficient is 1, which is completely absorbed)
Q:What are the differences between nano ceramic plate and ceramic fiber board?
The biggest difference between the two is that:1, the coefficient of thermal conductivity is different, the nano ceramic plate is about three times of the ordinary ceramic fiber board2, temperature class is not the same, nano ceramic board maximum temperature of 1050 degrees, ceramic fiber board should be 1400 degrees temperature.3, the range of applications is different. Nano ceramic plate is mainly used in high, fine and sharp technical fields, and has strict requirements on thermal conductivity. Ceramic fiber boards are widely used and can be used wherever there is flame or temperature.
Q:What are the uses of ceramic fiber boards?
Ceramic fiber board is the main use of heat insulation, fire protection, insulation to use, but also with sound absorption, noise reduction, thermal shock resistance and so on. Ceramic fiber board is mainly used in all kinds of furnace lining insulation, kiln wall lining insulation, metallurgical industry furnace fire, aluminum reduction tank, refractory brick backing.
Q:What are the standards for ceramic fiber boards?
Ceramic fiber board currently only GB, and many production enterprises are also in accordance with GB to perform.
Q:Is there any difference between ceramic silicon fiber board or ceramic fiber board?
1, high compressive strength, long service life; 2, low heat capacity, low thermal conductivity;3, non brittle material, good toughness;4, accurate size, good flatness;5 、 easy to cut and install, easy to construct;6, excellent wind erosion resistance;7 、 continuous production, uniform distribution of fiber, stable performance.
Q:How much pressure can the ceramic fiber board withstand?
Ceramic fiber fireproof plate, the density of 350-400Kg/m ceramic fiber board, fand; density above fand 400Kg/m.
