Tiger Hi-Clean Board suppresses the emission of formaldehyde even if the temperature rises

In a two-scenario experiment with and without Tiger Hi-Clean Board, the flooring, which is the source of formaldehyde emission, was placed in a container and the concentration of formaldehyde was measured. If the flooring has Tiger Hi-Clean Board, emission rate can be suppressed to the level of F☆☆☆☆ grade construction material, even if the temperature rises to 35 °C.
