PE Foam Expansion Joint Board, Elastic Concrete Filler for Road Bridge Crack Resistance & Construction Gap Sealing
Product Spotlights
Polyethylene (PE) foam board is a high-performance closed-cell foam material made from premium polyethylene resin through advanced foaming, extrusion and molding processes. As a versatile, lightweight and durable industrial and construction material, it has become a preferred choice for various industries due to its stable physical and chemical properties and comprehensive functional advantages. Featuring an independent closed-cell structure, the board boasts uniform foam density, smooth surface and stable overall dimension, avoiding deformation, shrinkage and cracking in long-term use.
One of the most prominent advantages of PE foam board is its excellent thermal insulation and heat preservation performance. The dense closed-cell structure locks static air effectively, greatly reducing heat conduction and convection, which delivers outstanding heat insulation and cold resistance effects. It can effectively isolate temperature difference, prevent cold bridge and heat loss, and is widely applied in building exterior and interior insulation, pipeline thermal protection and refrigeration equipment insulation. Meanwhile, the material has superior waterproof and moisture-proof capabilities. Its non-absorbent closed-cell structure completely blocks water and moisture penetration, ensuring stable performance in humid, rainy and underground environments without mildewing or rotting.
In addition, this foam board features excellent shock absorption, cushioning and sound insulation properties. With moderate hardness and good resilience, it can effectively buffer external impact, disperse pressure and reduce vibration damage, making it ideal for product packaging, equipment protection and engineering shockproof filling. Its internal porous structure can also absorb noise and reduce sound transmission, achieving a good sound insulation and noise reduction effect for building walls, floors and equipment rooms.
Made of eco-friendly non-toxic raw materials, the polyethylene foam board is harmless to human body and environment, with no peculiar smell and no harmful substance precipitation. It also has strong chemical stability, resisting acid, alkali, oil and corrosion, and is not easy to age and oxidize, realizing a long service life. The material is lightweight and easy to cut, process and install, which greatly saves construction time and labor costs. Suitable for construction expansion joints, road bridge isolation joints, industrial packaging, mechanical equipment protection and marine engineering, it is a cost-effective and multi-functional foam material with high practical value.
