The so-called low-foaming polyethylene closed-cell foam board actually refers to polyethylene closed-cell foam board. This foam board is a kind of low-density, high recovery rate, New waterproof material with independent bubble structure. The surface of foam board has low water absorption and good anti-penetration performance. It is resistant to corrosion by organic solvents such as acids, alkalis, salts, and oils, and has excellent aging resistance. It does not flow at high temperatures and does not crack at low temperatures. Low-foaming polyethylene closed-cell foam board (-) is widely used in expansion joints of concrete highway expansion joints, slabs, bridge joints, water conservancy engineering dams, dam protection, stilling sills, slope protection, and expansion joints of barrier walls. Settlement joints for board construction, caulking boards for frame structures Domestic water plants and sewage treatment plants pool water-stop caulking boards Seaming boards for airport runways Seaming boards for ports, docks, concrete joints Water tunnels, tunnel concrete water joints Concrete water-stop joint panels for subways and underground passages.
The high-expanded polyethylene closed-cell foam board refers to the polyethylene closed-cell foam board. The high-expanded polyethylene closed-cell foam board is harder than the lower-expanded polyethylene closed-cell foam board and is suitable for The cement joint filling board used for reservoir dams has the characteristics of low density, light bulk density, high recovery rate, high expansion and contraction strength, and a honeycomb-like appearance with evenly distributed holes and independent bubble structure. - has the best physical properties and is generally used in key national projects, such as the South-to-North Water Diversion Project.
