The honeycomb plate is very permeable and can reduce the airflow resistance. It is also can reduce the airflow noise. Our honeycomb plates have a strong resistance to low temperatures and are therefore difficult to freeze. Our honeycomb plating is mainly made of plastic, environmental protection, light weight, high strength, very durable. Polycarbonate cell core diameter we can provide from 3.5-10mm. The maximum pc honeycomb dimension is 3000x1500mm, thickness range are 4.5--400mm.
