Paper honeycomb sandwich panel is a new type of high-tech building material, which has gradually replaced traditional core materials such as rock wool, EPS and PU. The paper honeycomb sandwich panel has better performance than the traditional core material sandwich panels: it has higher flame retardancy, lighter self-weight, stronger load-bearing capacity, better sound insulation effect, and stronger environmental protection performance. Paper honeycomb purification panels have been widely used in clean building industries such as electronic, biological, food, pharmaceutical, hospitals, military, etc., and are products of modern buildings.
