>Density
>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, cork, rubber Compared with asphalt, polyethylene closed-cell foam boards have been widely used in concrete projects such as highways, railways, bridges, buildings and other concrete joints and expansion joints abroad, 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, 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 applies this new construction technology, which breaks many limitations of the construction of asphalt shank expansion joints. The construction is convenient, fast, and low in construction cost. In addition, the polysulfide sealant has the advantages of traditional petroleum asphalt. The hydrophobicity enhances its water resistance and aging resistance
>Classification of polyethylene closed-cell foam boards
>Polyethylene closed-cell foam boards are divided into two types, high foaming Foam board and low foam foam board.
>The medium type is suitable for cement joint filling boards in ordinary ditches and pools, and the medium type is suitable for cement joint filling boards in reservoir dams because of its hardness.
>Relatively hard, this product is pure black, generally used in water conservancy projects, water plants, power plants, etc.
>Physical characteristics
>Density
>High density, recovery rate High, with independent bubble structure.
>Water Absorption
>Low surface water absorption and good anti-penetration performance.
>Chemical Properties
>PH
>Resistant to acid, alkali, salt, oil and other organic solvents, and has excellent aging resistance.
>Stability
>Does not flow at high temperatures and does not crack at low temperatures.

>Hengshui Guangfeng Engineering Rubber & Plastic Co., Ltd. was established in In 2016, it is a modern enterprise integrating engineering rubber R&D and production. The polyethylene closed-cell foam board manufacturer is very advanced, and the polyethylene closed-cell foam board manufacturer 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 will help 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. I 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.
