Polyethylene foam board is a versatile thermal insulation material widely used in construction, cold storage, highway, and railway projects. Though it may not be as well-known as other materials, it plays a crucial role in ensuring structural integrity and energy efficiency. In this article, we will explore the features, applications, and construction methods of polyethylene foam board.
What makes polyethylene foam board stand out?
1. It exhibits excellent resistance to organic solvents such as acids, alkalis, salts, and oils, along with superior aging resistance.
2. Unlike some materials that become brittle or melt at extreme temperatures, polyethylene foam maintains its flexibility and strength both at high and low temperatures.
3. With a low density and high recovery rate, it features an independent bubble structure, making it lightweight yet durable.
4. The surface has a low water absorption rate, which enhances its anti-permeability and long-term performance.
5. Chemically cross-linked polyethylene foam offers unique advantages, including strong recovery, no water absorption, impact resistance, weather resistance, chemical resistance, and excellent aging resistance—qualities that are hard to find in other materials. As a result, its applications continue to expand across various industries.
How to install polyethylene foam board?
During construction, the board is typically placed on the inside of the concrete precast block template. Joints should be tightly sealed without overlapping. The boards are usually cut at the factory according to the specific dimensions of the structural joints, ensuring seamless connections at the seams for optimal performance.
Where is polyethylene foam board used?
This material is extensively used in concrete projects, particularly in expansion joints, bridge joints, overpasses, highways, airport runways, underpasses, tunnels, and subway stations. It also serves as a water stop material in roadways, power plants, cooling towers, and other infrastructure projects. Additionally, it is used as an elastic cushion layer for large-diameter pipes and as an antifreeze layer in channels.
