& 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, cork, rubber, and asphalt. For example, polyethylene closed-cell foam boards have been widely used in concrete joints, expansion joints and other concrete projects abroad such as roads, railways, bridges, buildings, etc., 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 boards and low-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.

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 & Plastic Co., Ltd. was established in 2008 and is an engineering rubber manufacturer. The polyethylene closed-cell foam board manufacturer, a modern enterprise integrating R&D and production, is very advanced. 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.
