The main effect of polyethylene closed-cell foam board is to prevent it from soaking, so polyethylene closed-cell foam board can be used as a joint board in the underground, water holes, ports, docks, water conservancy projects and other anti-deep all the needs of the local. In addition to the anti-soaking function, due to the small density of polyethylene closed-cell foam board, it can also resist the abnormal high temperature and low temperature, stability is also among the best in many materials guess. He also has very good anti-aging properties, whether it is encountered acid, alkali, salt, or oil will not be any effect. Buy polyethylene closed-cell foam board look for Hengshui Yifeng Technology Co., Ltd., is your trustworthy enterprise, polyethylene closed-cell foam board products are also known as: "polyethylene closed-cell foam board, closed-cell foam board, polyethylene "Foam board", which is a new type of joint sealing material in China. This product has been repeatedly tested by the Chinese Academy of Transportation Sciences and other units to prove that its performance is lower than that of wood, cork, rubber, and asphalt, and has a high recovery rate. Features. Before we use polyethylene closed-cell foam board, we must have a certain understanding of the scale of its use and its own function, so that it can be better used by ours. What are its applications and functions? The first thing to say is that the density of the polyethylene closed-cell foam board can be said to be very small, and its recovery rate is also very high. From the point of view of the physical structure, its bubble structure is very distinctive, so that its own structure and function are very stable in the process of application. If we look at the chemical properties of this product, it has a very good effect on pH. Therefore, it is possible to ensure that it will not be adversely affected in some environments where acid and alkaline corrosion is so simple. Its function is also very superior in terms of aging resistance. Let's put it in some high-temperature working environment and we don't have any doubt about not melting. In the low-temperature conditions, there is no doubt that any cracking will occur. Let's talk about the physical and mechanical properties of polyethylene closed-cell foam board: Apparent density 0.05-0.14g/m2 Tensile strength ≥ 0.15Mpa Compressive strength ≥ 0.15Mpa Tear strength ≥ 4.0N/mm Heat distortion ≤ 2.0% Water absorption ≥ 0.005g/cm3 Elongation ≥ 100% Hardness (C Hardness Tester) 40--60 Shore A. Degree of compression of permanent deformation ≤ 3.0% closed-cell foam panels using high-pressure polyethylene low-foam closed-cell foam panels, and sealant interaction material performance without change.
