Hengshui Guangfeng Engineering Rubber and Plastic Co., Ltd.

Product name Polyethylene high-density foam board type
Specifications*
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, softwood, rubber asphalt, and polyethylene closed-cell foam boards are It has been widely used abroad in concrete projects such as concrete joint expansion joints such as highways, railways, bridges, and bridges, and is 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 fir board expansion joints. The construction is convenient and fast, and the construction cost is low. In addition, the polysulfide sealant has the advantages of traditional petroleum asphalt. Hydrophobicity, enhances Jiwan Borneo Scholarship and improves 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 boards and low-foaming foam boards Foam foam board.
Among them, the medium type is suitable for making cement joint filling boards for ordinary ditches and pools, and the medium type is suitable for making cement joint filling boards for reservoir dams because of its hardness.
Relatively hard, this product is pure black, generally used in water conservancy projects, water plants, power plants, etc.

The closed-cell foam plastic board is made of high-pressure polyethylene low-foaming closed-cell foam plastic board, and the material properties will not change when interacting with the sealant.
Joint plates for airport runways
Joint plates for port and wharf concrete
Concrete water-passing joint plates for water tunnels
Concrete water-stop joint plates for subway underground passages.
Others
Precisely because chemically cross-linked polyethylene foaming has its unique advantages, strong recovery rate, non-water absorption, impact resistance, weather resistance, chemical resistance, and aging resistance are What other materials do not have, the application fields of foaming are becoming more and more extensive.

Hengshui Guangfeng Engineering Rubber and Plastic Co., Ltd. was established in 2008. It is a modern enterprise integrating the research and development and production of engineering rubber. Polyethylene closed-cell foam The board manufacturers are very advanced, and the polyethylene closed-cell foam board manufacturers are 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.
