Repeated tests by the Academy of Sciences of the Ministry of Communications and other units have proven that its performance is comparable to that of wood, softwood, rubber asphalt, polyethylene closed-cell foam Boards have been widely used abroad in concrete projects such as concrete joint expansion joints such as highways, railways, bridges, and bridges, and are also used in domestic hydropower projects.
In the construction of hydraulic expansion joints, closed-cell foam boards are used to replace the traditional three-oil, four-felt asphalt wood and fir boards and other materials, and the tops are filled and sealed with polysulfide sealant. The combination of closed-cell foam board and polysulfide sealant is a new construction technology that breaks many limitations of asphalt fir board expansion joint construction. The construction is convenient, fast and has low construction cost. In addition, the polysulfide sealant has the hydrophobicity of traditional petroleum asphalt and is more economical.

Classification of polyethylene closed-cell foam boards
Polyethylene closed-cell foam boards are divided into two types: high-foaming foam boards and low-foaming foam boards.
The medium-sized type is suitable for cement joint caulking plates for ordinary ditches and pools because it is relatively hard and suitable for cement joint caulking plates for reservoir dams.
Relatively hard, this product is pure black and is generally used in water conservancy projects, water plants, power plants, etc.
Physical characteristics

Precisely because chemically cross-linked polyethylene foam has its unique advantages, strong recovery rate, non-water absorption, impact resistance, weather resistance, chemical resistance, and aging resistance, it is a foam that other materials do not have. The application fields are becoming more and more extensive.

Hengshui Guangfeng Engineering Rubber and Plastic Co., Ltd. was established in 2006. It is a modern enterprise integrating the research, development and production of engineering rubber. The polyethylene closed-cell foam board manufacturer is a very advanced polyethylene closed-cell foam board manufacturer that is not easy to absorb water. If the humidity of the polyethylene closed-cell foam board manufacturer is too high, it will affect the thermal and mechanical properties of the material. The low water absorption of the polyethylene closed-cell foam board manufacturer helps to maintain these properties. Polyethylene closed-cell foam board manufacturers are not only environmentally friendly but also recyclable. Polyethylene closed-cell foam board manufacturers are recognized by many manufacturers and users in the industry. We believe that we will rely on our company's profound skills and honest business methods to bring high-quality polyethylene closed-cell foam board manufacturers to our users.
