What is the compressive strength of calcium silicate board with a density of 300? Calcium silicate board with a density of 300 kg/m ³ has a moderate to low compressive strength and is suitable for non structural insulation and fire protection applications with low load-bearing requirements.
                                                                

The relationship between density and strength

The strength of calcium silicate board is directly positively correlated with its density. The higher the density, the denser the internal structure, the stronger the bond between fibers and fillers, and the higher the compressive and bending strength.
Density of 300 kg/m ³: It belongs to the common density range of insulation boards, and its design intention is to balance low thermal conductivity (good insulation) and certain mechanical strength. Calcium silicate board with a density of 300 kg/m ³ is an excellent lightweight insulation and fireproof material. Its compressive strength is sufficient to meet its design purpose as a "covering layer" and "filling core material", but it cannot be used as a structural load-bearing component.


How to obtain accurate data

The most reliable approach is to request the 'Technical Data Sheet' or 'Testing Report' of the product from the supplier. You should focus on the following parameters:
Compressive strength: a clearly marked value, usually measured in MPa or N/mm ².
Bending strength: For sheet metal, bending strength is sometimes more critical than compressive strength, as it reflects the ability of the sheet metal to resist bending deformation.
Execution standard: Which national standard does the product comply with (such as GB/T in China, ASTM in the United States, EN in Europe), and the strength grade will be specified in the standard.

Aluminum foil glass wire mesh rock wool roll felt: Rosetexwool empowers multi scene insulation

In the fields of industrial pipeline transportation, building wall and roof construction, the quality of insulation performance is directly related to energy loss control, environmental comfort improvement, and engineering safety assurance. Improper insulation of large-diameter pipelines can increase energy consumption due to temperature loss; If the walls and roofs of buildings lack efficient insulation layers, it can lead to cold winters and hot summers, significantly increasing the cost of air conditioning and heating. Rosewool Insulation Refractory Co.,Ltd has launched a glass fiber reinforced plastic wool roll felt with aluminum foil, which, with its unique structural design and excellent performance, has become a high-quality choice for solving insulation problems in multiple scenarios. ​

ceramic fiber  plus blanket

What is the difference between ceramic fiber blanket plus blanket and international Morgan blanket?

What is the difference between ceramic fiber blanket plus blanket and international Morgan blanket? Rosetexwool's ceramic fiber blanket PLUS blanket refers to various insulation and refractory products with high temperature resistance, low thermal conductivity, lightweight, thermal shock resistance, sound absorption and other characteristics made from hard clay clinker, coke gemstone, alumina silica powder and other raw materials, melted in a high-temperature resistance furnace (above 1600 ℃), blown/spun into fiber cotton, and processed through different processes (needle punching, heat setting, cross cutting, rolling, etc.). Its core is to utilize the microstructure of ceramic fibers (fibers interwoven to form a porous and loose structure) to achieve efficient insulation, better thermal insulation, and more stable structure under high temperature environments, widely applicable to industrial high temperature working conditions and fire protection scenarios.

Ceramic fiber module

Ceramic fiber module: an excellent choice for industrial kilns

In the world of industrial kilns, for industrial enterprises facing environmental pressure, choosing ceramic fiber modules can not only meet environmental acceptance standards, but also enhance the green image of the enterprise. Under the promotion of the national "dual carbon" target, the demand for energy-saving and consumption reducing materials by enterprises has become increasingly urgent. The energy-saving rate of ceramic fiber modules, which is around 30%, perfectly fits this trend and has become the preferred material under policy guidance.
