Phenolic material density

Density of phenolic materials
The density of phenolic materials mainly depends on their specific application form. The density of phenolic foam insulation board is usually below 100 kg/m3, and can reach about 50 kg/m3. This characteristic makes phenolic insulation board have good aging resistance, and can reduce the weight of the building, reduce the load of the building, and reduce the cost of the structure. At the same time, the construction is simple and fast, which can improve work efficiency1. On the other hand, 201 phenolic resin is a reddish-brown liquid with a density between 1.20 and 1.30 g/cm3 and a solid content of 45% to 55%. This resin is soluble in ethanol and its viscosity does not exceed 40 mPa·s2 at 25°C. Although both materials are phenolic materials, their densities are different due to their different application forms. Phenolic foam insulation board has a lower density due to its porous structure and is suitable for use as an insulation material; while 201 phenolic resin has a higher density due to its liquid form and higher solid content, and is usually used in the production of anti-corrosion coatings and adhesives.
