Phenolic insulation board is mainly made of phenolic foam, which is mainly composed of phenol and formaldehyde. Phenolic foam is a new type of fire-resistant, fireproof and low smoke insulation material (under limited conditions). It is a closed cell rigid foam plastic made of phenolic resin added with foaming agent, curing agent and other additives.
Phenolic molecules only contain carbon, hydrogen, and oxygen atoms. When subjected to high-temperature decomposition, apart from producing a small amount of CO gas, no other toxic gases will be produced, with a maximum smoke density of 5.0%. The 25mm thick phenolic foam plate, after being sprayed with a flame at 1500 ℃ for 10 minutes, only slightly carbonized on its surface but could not burn through. It would neither catch fire nor emit thick smoke and toxic gas. In addition to being corroded by strong alkali, the phenolic foam could resist the corrosion of almost all inorganic acids, organic acids and organic solvents. Long term exposure to sunlight without obvious aging phenomenon, therefore it has good aging resistance.
Phenolic insulation board is an environmentally friendly and green product that does not irritate the skin or cause any harm to the human body. It releases non-toxic smoke during combustion.
So phenolic insulation board is an environmentally friendly and safe insulation board, which is a high-quality choice.
