The main effect of the polyethylene closed-cell foam board is to prevent penetration. Therefore, the polyethylene closed-cell foam board can be used as a joint board in underground areas, water holes, ports, docks, water conservancy projects, etc. In addition to the function of anti-soaking, due to the low density of polyethylene closed-cell foam board, it can also resist abnormal high temperature and low temperature. The stability is also one of the best in many materials. He also has very good aging resistance, no matter whether it is acid, alkali, salt or oil.
Buy Polyethylene closed-cell foam board and look for Hengshui Yifeng Technology Co., Ltd., which is your trustworthy enterprise. Polyethylene closed-cell foam board products are also called: "Polyethylene closed-cell foam board, closed-cell foam board, polyethylene "Foam board", which is a new type of seam sealing material in China. This product has been tested repeatedly to prove that its performance has the characteristics of low density and high recovery rate compared with wood, cork, rubber and asphalt. 
Before using polyethylene closed-cell foam board, we must have a certain understanding of the scale of its application and its own functions, so that it can be better used by us. So what is its application and function?
First of all, the density of the polyethylene closed-cell foam board can be said to be very small, and the recovery rate is also very high. From the point of view of the physical structure, its bubble structure has obvious special characteristics, so that its own structure and function are determined to be very stable in the process of application. If we look at the chemical properties of this product, it can have a very good resistance to pH. So in some environments where acidity and alkalinity are so simple and corrosive, you can be sure that you will not suffer any adverse effects. Its function is also very good in terms of aging resistance. Let's put it in some high-temperature work environment without any doubts about it. There is no doubt that any brittle cracks will occur under low temperature conditions.
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 deformation ≤2.0% Water absorption ≥0.005g/cm3 Elongation ≥100% Hardness (C Type hardness tester) 40--60 Shore A. The degree of compression deformation ≤3.0% closed-cell foam plastic plate uses high-pressure polyethylene low-foam closed-cell foam plastic sheet, and the performance of the material interacting with the sealant is unchanged.
