How to choose the quality of PU line board? 2021-04-21 15:36:00

Wire boards of the same material, the heavier is better. For wire boards with the same color width, it can be found from the size of the holes on the side that the foaming density of the wire boards is sparse or dense, and the density is insufficient, and cracks and even embrittlement are more likely to occur when they expand and contract with heat. The denser the pores, the higher the proportion of plastic, and therefore the heavier weight. Conversely, if the proportion of plastic is low, it also means that the amount of blowing agent added is larger, which is relatively lighter and the pores are larger.
