What is the difference between thermal insulation cotton and thermal insulation sand?
Thermal insulation cotton: moisture-proof panel composite on line, because it has a large number of small air voids, so that it plays the role of thermal insulation, sound absorption, noise reduction and safety protection, and is the best material for building thermal insulation, sound absorption and quenching. Suitable for a wide range of temperature, from -40 to 105 degrees Celsius, and anti-aging properties, durable. The flame retardant effect reaches the national B1 standard.
The heat-resistant temperature of the two is different, the cotton is higher, the board is lower. Where the cotton can wrap round pipes, and so on, it can only be used in larger planes.
Rubber and plastic panels: with excellent fire resistance. In accordance with the national standard GB/T17794-1999, "building materials combustion classification method", rubber sponge insulation board was tested to determine "GB/17794-1999B1" refractory material. The service temperature range is from -50 DEG C to 110 DEG C.
