Closed Cell Polyethylene Foam Board

The closed cell polyethylene foam board has a unique bubble structure. Its surface is covered with evenly spaced, honeycomb-like holes. It can be firmly and closely integrated with cement-based adhesives. It easily adjusts to changes in size. This boosts its ability to stop water during expansion.

Closed Cell Polyethylene Foam Board

1. Low density and high recovery rate, with an independent bubble structure.

2. Low surface water absorption rate and excellent anti-permeation performance.

3. Corrosion-resistant to acids, alkalis, salts, oils, and organic solvents. It also has great aging resistance.

4. It does not flow at high temperatures and does not crack at low temperatures.

Application scope:

1. Joint board for concrete highway expansion joints.

2. Joint water-stopping board for bridges and roads.

3. Engineers use expansion joint boards in dams, retaining walls, energy dissipation aprons, and slopes in water conservancy projects.

4. Water-stopping joint boards sit at the bottom of water towers. Engineers use them in hydropower, thermal power, and other engineering projects.

5. Settlement joint and frame structure-filling board for buildings.

6. Water-stopping filling board for water tanks in water supply plants and sewage treatment plants.

7. Joint board for airport runways.

8. Joint board for ports, docks, and concrete.

9. Water passage joint board for water tunnels and tunnel concrete.

10. Water-stopping joint board for concrete in subways and underground passages.
