With the increasingly widespread use of phenolic insulation boards, many questions have been raised about how to select suitable and high-quality phenolic insulation boards. Next, I will introduce some basic methods for selecting phenolic insulation boards.
1.First of all, it is necessary to observe whether the production is carried out using blisters. Generally, products produced using this method have a relatively low density, a brittle plate body, are prone to breakage, and are prone to pulverization or slag falling.
2.The other type is the phenolic insulation board produced by the assembly line, known as the modified phenolic insulation board. It is a modified phenolic insulation board produced by improving the phenolic resin and foaming process. This kind of phenolic insulation board overcomes the shortcomings of its own pulverization and slag deposition to a certain extent, so the density of the modified phenolic insulation board is generally above 55KG.
3.During the selection process, we can also observe the appearance of the phenolic insulation board, use hand pressure to check the density, break it apart to check the toughness of the insulation board, and use hand friction to observe whether it will pulverize and drop slag.
