DESCRIPTION
The product description
The double sided aluminum foil phenolic composite board is composed of phenolic foam and aluminum foil at high temperature. Phenolic foam is the most ideal green thermal insulation material for fire prevention, heat insulation, energy conservation, beauty and environmental protection. Experiments show that the 25mm thick phenolic foam plate is slightly carbonized but cannot burn through after being sprayed by a 1700 ℃ flame for 10 minutes, neither will it catch fire nor will it announce smoke and toxic gas, so it has broad market prospects.
The inner and outer layers of double-sided aluminum foil phenolic composite air duct are embossed aluminum foil with anti-corrosion and anti bacteria coating, and the central insulation layer is hard phenolic foam. Made by using common resin modification, double-layer aluminum foil surface chemical treatment and other processes.
