Comparison of tensile strength of EPS board and XPS extruded board?
First of all, the strength here refers to the tensile strength of EPS board and XPS extruded board. The tensile strength of ordinary EPS boards on the market is 105-140KPa, but the tensile strength of EPS boards of different specifications is different. Compared with EPS, the strength of XPS extruded board is higher, and the nature of EPS sheet is relatively brittle. When pasting on a large area, the possibility of cracking of the outer wall and the coating surface layer is higher.
The tensile strength also has a certain relationship with the bulk density of the board. The tensile strength of the EPS board with a bulk weight of 18Kg per square is 100-110Kpa, and the tensile strength of an EPS board with a bulk weight of 20Kg per square is about 130Kpa. Compared with the EPS board, the tensile strength of the XPS extruded board is higher, because its main quality assessment is the tensile strength. At present, the tensile strength of many XPS extruded boards in China reaches 200Kpa, while most of the domestic EPS boards have tensile strength. The strength is below 100Kpa. In the case of more and more abundant exterior wall decoration and frequent typhoons in coastal areas, strength is very important, so the application of XPS extruded board in this area is generally higher than EPS board.
From the above data, it can be seen that compared with the tensile strength of the XPS extruded board, the EPS board still has the advantage of the XPS extruded board, so in the construction industry, the selection of materials has also become the top priority, in uneven building materials The quality of XPS extruded board in the market is to be believed.
