Color steel sandwich panels not only have the properties of high mechanical strength and easy forming of steel materials, but also have good decorative and corrosion resistance of coating materials. Color steel sandwich panel is an emerging material highly regarded in the world today. With the advancement of technology, the enhancement of environmental awareness, and the improvement of people's living standards, color steel sandwich panel activity rooms are increasingly showing strong vitality and broad market prospects, and are favored by construction, home appliances, electromechanical, transportation, interior decoration, office equipment, and other industries.
The cores used for color steel sandwich panels mainly include phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, tri polyester and rock wool. Phenolic foam has excellent fire and thermal insulation performance, which cannot be replaced by other materials. For example, the thermal insulation effect of phenolic foam is more than twice that of polystyrene, and its fire resistance is also higher than that of polyurethane. When polyurethane burns, it will release thick smoke containing hydrogen cyanide.
With the increasing attention of the country to building fire prevention and the introduction of relevant laws, it is believed that phenolic resin color steel sandwich panels will create a blue sky in the field of construction.
