How to use foam board During construction, polyethylene closed cell foam board can be used in a variety of ways according to the situation. Used for longitudinal water-stop joints, horizontal water-stop joints and other special joints. Foam board/>Polyethylene closed-cell foam board has its unique advantages, strong recovery rate, no water absorption, impact resistance, weather resistance, chemical resistance, and aging resistance that other materials do not have. Foaming The application fields are becoming more and more extensive. The closed-cell foam board has an independent closed-cell bubble structure, and the honeycomb-shaped holes are evenly distributed. Integrates firmly and tightly with the cement binder. Naturally adapts to changes in expansion and contraction, enhancing the expansion and water-stopping effect.
The application range of closed-cell foam boards can be widely used in various concrete water-stop joint projects such as river dams, port terminals, underground tunnels, hydropower stations, airport bridges, and residential sanitation.

Low-foaming polyethylene closed-cell foam board is a high-pressure foam board with an expansion rate. It has a pure black appearance and a rough surface with obvious pores. The texture is very hard, like a wooden board, but its flexibility is not as good as that of closed cells. Board, the compressive strength and compressive strength are very high, reaching the highest level among foam boards. Due to its performance and cost, high-pressure polyethylene closed-cell panels are mainly used in large-scale hydropower transportation projects such as high-speed railways, airports, and face dams.
