You might have just heard of closed-cell foam board for the first time. It's a commonly used material in many of our dams and wharfs. But do you know what it really is? Today, we'll take a closer look at closed-cell foam board and explore its features, applications, and benefits.
What is closed-cell foam board?
Closed-cell foam board is known for its high density, which has made it a popular replacement for traditional materials like three-oil four felt, asphalt, and wood fiber boards. One of its key advantages is that it's environmentally friendly—using it supports the global push for sustainability. Its installation is straightforward, and it delivers excellent anti-seepage and leak-proof performance. The density of the board plays a crucial role in its waterproofing capabilities. Because of its low density, it significantly improves water resistance, with extremely low water absorption measured in cm³.
Beyond its strong waterproof properties, closed-cell foam board offers a range of other benefits. It is resistant to cold temperatures without becoming brittle, and it doesn't melt under high heat. It also resists corrosion from acids, alkalis, and other chemicals. Its independent bubble structure gives it a high recovery rate and makes it resistant to aging. These features make it an ideal choice for a wide variety of construction and engineering projects.
Currently, closed-cell foam board is widely used in various applications, including expansion joint boards for concrete highways, water-stop boards for road and bridge joints, expansion joint boards for dams, slopes, and retaining walls in hydraulic projects, as well as water-stop joint plates in thermal power plants, water towers, and more. It’s also used in settlement joints for buildings, frame joints in frame structures, and water joints in domestic water treatment and sewage facilities. Additionally, it finds use in airport runways, ports, docks, tunnels, subways, and underground passages.
Key Features of Closed-Cell Foam Board
1. Low density with a high recovery rate and an independent bubble structure.
2. Low surface water absorption and strong resistance to permeation.
3. Resistant to corrosion from organic solvents like acid, alkali, salt, and oil, along with excellent aging resistance.
4. Does not flow at high temperatures and remains flexible at low temperatures.
Applications of Closed-Cell Foam Board
Closed-cell foam board is widely used in concrete projects such as highway expansion joints, road and bridge expansion joints, overpasses, airports, underpasses, underground passages, subways, bridgehead barrier walls, slope protection on both sides of highways, and roadbed slope protection. It is also used in concrete joints, expansion joints, and water-stop materials for roads, viaducts, culverts, tunnels, airport runways, dam slope protection, and other hydraulic projects in power plants, cooling towers, and construction sites.
