phenolic foam board is made of phenolic foam material. Phenolic foam material is a polymer organic rigid aluminum foil foam product, which is foamed by thermosetting phenolic resin. phenolic insulation boards are widely used in developed countries. According to statistical data and literature records, 40% of fire insulation and sound insulation materials in the United States are phenolic resin; the United Kingdom, Western Europe, and the Middle East stipulate that phenolic foam insulation should be given priority to new projects; the construction departments of France and the Nordic region believe that only phenolic foam insulation has better fire resistance properties. Russia and Eastern Europe also widely use phenolic foam insulation materials in public buildings and high-rise buildings; Japan even promulgated the decree "Phenolic foam as standard building fire-resistant materials".
Phenolic faced plywood introduction
Phenolic foam is known as the "King of Thermal Insulation Materials" and is a new generation of thermal insulation, fireproof and sound insulation materials. It has the properties of light weight, fire resistance, non-burning in open flame, smokeless, non-toxic, non-drip, etc., and has a wide temperature range of use. As a safe and green new energy-saving building material, the advantages of phenolic foam have been recognized by the construction department and the public security fire department.
1) Phenolic foam was early used in the insulation of missiles and rocket heads.
2) Widely used in high-rise buildings, transportation, ships, aviation, space technology and other fields.
3) In the field of pipe insulation such as petrochemical industry, pipe and shell products cut by phenolic insulation board are also widely used.
4) Composite products of phenolic insulation board are used in large-mold built-in systems in building insulation projects, A-class fire insulation systems, integrated building wall insulation and decoration systems, fire door interlayers, color steel sandwich panel houses and other fields.
