What Is Phenolic Foam?
Phenolic foam is a type of foamed plastic insulation material in which phenolic resin is foamed into microscopic bubbles to seal in highly insulating gases, thereby providing excellent heat insulation properties. Despite its thinness, it offers sufficient heat-insulating performance and has recently become widely used as a heat-insulating material for houses. The foaming gas used is a hydrocarbon gas, noted for its low global warming potential, making it an environmentally friendly heat insulator.
In addition to its high heat insulation performance, phenolic foam possesses excellent heat resistance, sound absorption, flame resistance, low smoke emission, cryogenic properties, and chemical resistance. While the construction cost increases with improved insulation properties, the overall cost can be reduced considering the running costs post-completion.
Uses of Phenolic Foam
Phenolic foam, when used as an insulating material in houses, significantly reduces heating and cooling expenses. It minimizes temperature differences within the building and reduces radiation from walls and floors, contributing to a comfortable living space.
With its exceptionally high thermal insulation performance and thin construction, phenolic foam is ideal for external insulation, where the walls, roof, and floors of a building are wrapped with insulation material. As a means to mitigate global warming, the demand for highly insulated building materials is increasing.
Its non-housing applications extend to semiconductor and automotive parts, cookware handles, and tableware.
