Closed-cell foam board, polyethylene foam board, polyethylene closed-cell foam board, foam board type, closed-cell foam board type, closed-cell foam board. Closed-cell foam board has an independent closed-cell bubble structure and evenly distributed honeycomb-shaped holes. Integrates firmly and tightly with the cement binder. Naturally adapts to changes in expansion and contraction, enhancing the expansion and water-stopping effect.
Features
