Honeycomb is totally different from our AFP and it can only be used for heat resistance. But our AFP can not only be used for heat-resistance, but also for sound inslutaion, sounfproof and energy-absorption.
The density of honeycomb aluminum floor is higher than the ultra light porous aluminum foam floor because the aluminum section frame is needed for honeycomb aluminum floor sides but not for the ultra ligh porous aluminum foam sanwich board. It results the costs for the honeycomb aluminum floor is much higher. Furthermore, the ultra light porous aluminum foam sandwich board has much higher performance in mechanism strength, sound-proofing, shock absorption, heat-insulating than honeycomb aluminum.
