In recent years, aluminum foil phenolic foam insulation board is the first choice of wall insulation materials popular in South Korea.
Phenolic foam is also the most promising new thermal insulation material among the internationally recognized buildings. Because this new material is essentially different from the material obtained by adding flame retardants to common polymer resins. It does not burn, melt, or emit toxic smoke in fire. It has the advantages of light weight, non-toxic, non corrosive, heat preservation, energy conservation, sound insulation, low price, and does not need Freon foaming. It has no environmental pollution, good processability, and convenient construction. Its comprehensive performance is unmatched by various current heat preservation materials. It is generally used for thermal insulation of central air-conditioning systems in hotels, apartments, hospitals and other high-level and high-rise buildings (in recent years, most of the central air-conditioning systems in high-level buildings in Hong Kong have changed to phenolic foam materials).
Phenolic foam material is a polymer organic hard aluminum foil foam product, which is foamed from thermosetting phenolic resin. It is lightweight, fireproof, non flammable when exposed to open flames, smokeless, non-toxic, and non dripping. It has a wide temperature range (-196~+200 ℃) and does not shrink or embrittle in low temperature environments. Because of its high closed cell ratio, phenolic foam has low thermal conductivity (can be lower than 0.030w/mk), good thermal insulation performance, and certain water resistance and water vapor permeability. It is a good thermal insulation and energy saving material, and also an ideal thermal insulation material for HVAC engineering. Due to the benzene ring structure of phenolic aldehyde, its size is stable with a change rate of<1%. And the chemical composition is stable, anti-corrosion and anti-aging, especially resistant to organic solutions, strong acids and weak alkalis. In the production process of foaming, Freon is not used as foaming agent, which conforms to the international environmental protection standards, and its molecular structure contains hydrogen, oxygen and carbon elements. During high-temperature decomposition, the spilled gas is non-toxic and tasteless, harmless to human body and environment, and conforms to the national green environmental protection requirements. Therefore, phenolic super composite board is an ideal environmentally friendly and green insulation material for fire prevention, insulation, energy conservation, and aesthetics.
