Phenolic Foam (PF) is a type of rigid plastic foam made up of phenolic resin and other additives. It is widely recognized as one of the best insulation materials due to its exceptional fire resistance, low smoke emission, high temperature resistance, stability, superior thermal performance, excellent sound insulation properties, and strong structural strength. Because of these qualities, it is often referred to as the Third-Generation insulation material.
The thermal conductivity of Phenolic Foam is very low, ranging from 0.021 to 0.032W/mk. This is much lower than traditional insulation materials such as mineral wool, rock wool, glass wool (which have a thermal conductivity of 0.043 to 0.052W/mk), and expanded perlite (which has a thermal conductivity of 0.065 to 0.083W/mk). In fact, its energy-saving and insulation performance is double that of these traditional materials and is on par with polyurethane. Therefore, it is widely regarded as one of the top insulation materials in the world.
