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?
Sheng Yang series of ceramic fiber board is based on the traditional process of comprehensive upgrading of the excellent vacuum forming insulation materials, slag ball content of less than 3%, fiber distribution uniformity, internal and external strength consistent, size controllable.Ceramic fiber board is made by spraying superfine ceramic fiber through water washing, slag removal, fiber freezing and vacuum forming. The product has superior high temperature resistance, excellent rigidity and toughness.
Q:What is the difference between ceramic fiber board and nano ceramic fiber board?
The traditional ceramic fiber board has good heat insulation, high temperature resistance to certain characteristics, widely used in kiln products, but this tradition also has some shortages, low intensity, high temperature and high pressure, there are restrictions on the application of kiln stress.
Q:Ceramic fiber plate and aluminium silicate plate are chosen as lining materials
Volume density is low: the density of the ceramic fiber lining is about 25% of the lining of the light heat insulation brick, about 10% of the lining of the light pouring material; adopting the fiber lining can greatly reduce the steel structure load of the furnace and prolong the service life of the furnace lining.
Q:What are the specifications of the ceramic fiber board?
Ceramic fiber board, also known as aluminum silicate or refractory fiber, including ceramic fiber blanket, ceramic fiber, ceramic fiber fireproof plate (plate).
Q:What are the sound-absorbing fiber boards?
Sound-absorbing material:1, itself has sound-absorbing properties, porous fiber material.2, does not have sound-absorbing material, but processed into sound absorption structure.Common sound-absorbing materials are: polyester fiber sound-absorbing board, trough wood sound absorption board, hole wood sound-absorbing board, recycled wood sound-absorbing board, the latest is Dr. sound, high temperature ceramic sound-absorbing board, a fire prevention, water quality, hard environmental protection
Q:What are the differences between nano ceramic plate and ceramic fiber board?
Ceramic fiber board is a kind of ceramic fiber cotton produced by injection technology. It is made by continuous production and advanced technological production line.
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?
Ceramic fiber board is aluminum silicate fiber board, a refractory material. Even after heating, good mechanical strength is maintained. The product is a fibrous insulation product that is rigid and has a supporting strength compared to fiber blankets. Features: ceramic fiber board has excellent quality, toughness and strength, besides, it has excellent resistance to wind erosion. The utility model has the advantages of no heat expansion, light weight, convenient construction, and arbitrary shearing and bending. The utility model is an ideal energy-saving material for kilns, pipes and other heat preservation equipment.
Q:How much pressure can the ceramic fiber board withstand?
Ceramic fiber board has the characteristics of tough, high compressive strength, excellent resistance to high temperature and excellent supporting force. The compressive strength of ceramic fiber board increases with the increase of density of ceramic fiber board.
Q:What method should be used to measure the thermal conductivity of fiberboard?
It is concluded that the test error of this method and device is about 2%. This filament ultra light aluminum silicate fiber product: the filament ultra light aluminum silicate product is by Shandong Zibo high quality burnt precious stone as raw material, passes through the smelting furnace, the rejection silk, blows the cotton, the auxiliary mold and so on to deliver the work procedure. Therefore, the thermal conductivity of fiberboard is chosen by heat flow meter method.
