A highly functional corrugated sheet that has a heat ray shielding effect in addition to the original toughness of polycarbonate. It suppresses the temperature rise of the part where the transmitted light hits and is also effective as a measure against ultraviolet rays. The heat ray absorption type (smoke gray, smoke bronze, smoke amber frost) is suitable for lighting, and the heat ray reflection type (super milk) is suitable for light shielding.

Test method:
Using a tester as shown above, irradiate an infrared lamp for a fixed time (20 min) and measure the temperature change of the thermocouple installed on the black panel.

Each data is a representative value measured by us, not a guaranteed value.
