The adiabatic melting temperature of calcium silicate is about 2000°C. The heat-resistant temperature of asbestos rope is 500°C for all asbestos fibers, 250°C for cotton fibers with a content of less than 10%, and 350°C for those filled with magnesium carbonate. The heat-resistant temperature of asbestos cloth is 500℃. The heat-resistant temperature of asbestos thread is 700°C. The heat-resistant temperature of asbestos yarn is 500°C.


High-temperature foam material for the insulation of industrial equipment and pipelines, using thermal insulation measures and material aerogels to be applied to the thermal insulation lining of space suits researched by the National Space Administration. It has the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof. Traditional polystyrene boards and inorganic insulation boards have excellent thermal insulation effects. They are widely used in China’s wall insulation materials market, but they do not have safe fire performance, especially when they burn to produce poisonous gas. In fact, the use of high-temperature resistant foam materials, In developed countries, it has long been restricted to very small application areas.



Organic thermal insulation materials mainly include polyurethane foam, polystyrene board, and phenolic foam. Organic thermal insulation materials have the advantages of light weight, good processability, high compactness, and good thermal insulation effect, but the disadvantages are: not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological and environmental protection, construction The difficulty is high, the project cost is high, its resources are limited, and it is difficult to recycle.


Through additional treatment, a high-noise interception can be obtained, and the sound insulation effect is good; the appearance is exquisite, and the interior is practical: through various processing treatments, suitable for interior decoration; high temperature resistant foam with high temperature resistance of more than 1100 degrees, resistance to various acids and alkalis Corrosion, good permeability, uniform pore structure, fast heating and heat transfer.
