Polyethylene closed cell foam board |

Working Principle
|
The working principle of polyethylene closed cell foam board is mainly based on its unique closed cell structure and material characteristics. Polyethylene closed cell foam board forms a large number of small, independent closed cells inside the material through a special foaming process. The average diameter of these closed pores is usually between 0.1mm and 1mm. These closed pore structures effectively prevent moisture infiltration and can keep the board dry even in humid environments, making them an ideal choice for fields such as water conservancy engineering and basement waterproofing. At room temperature, polyethylene material is softened by the dissolution and expansion of strong solvents, creating conditions for the foaming expansion and control of its internal foaming agent, and maintaining a high viscosity liquid or plastic state of the raw material in the foaming container. Open the valve, as the external pressure is much lower than the internal pressure of the container, polyethylene is sprayed out under pressure. At the same time, the foaming agent contained inside vaporizes and generates pressure, causing the softened granules to expand and form foam holes, forming foam. |

Product Structure
|
Polyethylene closed cell foam board is a kind of sheet material with unique closed cell bubble structure. This material is mainly made of high-pressure polyethylene particles, added with various auxiliary materials such as crosslinking agents and foaming agents, and processed through processes such as mixing, refining, vulcanization, and high-temperature mold shaping. The structural characteristics of its product are mainly reflected in its closed cell bubble structure, which is evenly distributed inside the material, forming independent closed cells, making the material have low water absorption and good anti-seepage performance. In addition, polyethylene closed cell foam board also has the characteristics of firm and close integration with cement adhesive, which can naturally adapt to expansion and contraction changes, thus enhancing the expansion and water stop effect. |

Applications
|
The application scenarios of polyethylene closed cell foam board are very wide, mainly including construction engineering, water conservancy engineering, transportation engineering and many other fields. In construction engineering, polyethylene closed cell foam board is often used to fill expansion joints, settlement joints and construction joints, as well as the gap filling of external wall insulation system, auxiliary materials for roof waterproof engineering, and the sealing of gaps between doors, windows and walls. In hydraulic engineering, it is used for dams, guardrails, dissipation barriers, slope protection, and expansion joint plates, and has the characteristics of strong impermeability and drainage. In traffic engineering, polyethylene closed cell foam plate, as the joint plate of highway expansion joint, water stop plate of road and bridge joint, joint plate of airport runway and concrete joint plate of port and wharf, shows good solidity and stability. In addition, it is also applied to projects with food grade requirements such as water plants and reservoirs, as well as pond waterproofing and joint filling boards in sewage treatment plants, with anti-corrosion and acid alkali resistance characteristics. In the packaging industry, polyethylene closed cell foam board has become an ideal packaging material for electronic products, precision instruments and other valuables due to its excellent cushioning and seismic performance. Meanwhile, it also has applications in cold chain, furniture and other fields. |
