Aluminum foil phenolic insulation board has the characteristics of lightweight, fireproof, non combustible when exposed to open flames, smokeless, non-toxic, and non dripping. It has a wide temperature range (-159~+200 ℃), and does not shrink or embrittle in low temperature environments. Because of its high closed cell ratio, phenolic foam has low thermal conductivity (0.022~0.025w/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%. 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.
