What kind of phenolic pre-insulation board is produced? I believe many people do not know that it is actually made of phenolic foam. The phenolic board is a new type of non-combustible, fireproof, and low-smoke insulation material. It is a closed-cell rigid foam made of phenolic resin with a foaming agent, curing agent and other additives.

Its most prominent feature is non-combustibility, low smoke, and high-temperature resistance. It overcomes the shortcomings of the original foam plastic insulation material that is flammable, smokey, and deforms when exposed to heat, and retains the characteristics of the original foam plastic insulation material in lightweight and convenient construction. Phenolic foam is a new, non-flammable, flame-retardant, low-smoke insulation material, which is mainly made of phenolic resin injected with a foaming agent, curing agent and other additives.

Phenolic insulation board has a very friendly fire protection function. It is made of phenolic foam. Other materials can generally be made into composite materials for building insulation. Basically, reach the national fire protection level. It is basically possible to end the possibility of these insulated fires. The operating temperature range is generally between minus 250 degrees and minus 150 degrees. The heat preservation effect is very strong, and it has a good heat preservation effect. The flame retardant performance of the phenolic insulation board reaches more than 1 hour, and it is impermeable.

The highest burning performance of the phenolic insulation board is Class A, the highest operating temperature is 180℃ (allowing instantaneous burning 250℃), and the flame retardancy of 100mm thick phenolic foam can reach more than 1h. Under the direct action of the flame, there is carbon deposition, no dripping, no curling, and no melting. After burning, a layer of 'graphite foam' is formed on the surface of the flame, which effectively protects the foam structure in this layer.
