Polyethylene foam caulking board is a new type of joint water-stopping material in China. It has been proven by repeated tests by the Chinese Academy of Communications and other units that its performance is comparable to that of wood, cork, rubber, and asphalt. Polyethylene foam caulking board is popular abroad. It has been widely used in joints and stops in concrete projects such as highways, road bridge expansion joints, overpasses, highways, airport runways, tunnel bridges, underground passages, subways, bridgehead retaining wall joints, highway side slope protection, roadbed slope protection and other concrete projects. Water materials, concrete joints, expansion joints and water-stopping materials in power plant moisture gates, cooling towers, construction and other projects, concrete highways, viaducts, culvert tunnels, airport roads, dam slope protection and other water conservancy and power concrete projects. Product features: low density, high recovery rate, and independent bubble structure. , Low surface water absorption and good anti-penetration performance. , resistant to corrosion by organic solvents such as acids, alkalis, salts, and oils, and has excellent aging resistance. , does not flow at high temperatures and does not crack at low temperatures. Low foaming product physical and mechanical properties table test items measurement unit standard requirements density//compressive stress compression recovery rate extrusion volume bending load bending degree is not cracked, the bending force should be greater than the tensile strength breaking elongation rate frost resistance
