WPC sheet and Its Density: Perception and Facts
There is a lot of discussion about WPC density, which should be adequately understood. Density calculations can usually be made based on the mass per unit volume. The point is that “the density of the WPC material should be determined and stated based on the end use/end use”. WPC boards with a density of 0.55 or 0.60 used to make furniture are perfect. Because PVC/WPC panels are used in furniture construction in a “screw and glue process” only when the solvent welds the PVC materials together, the screws can also be used on solvent-welded (cyanoacrylate) PVC handles to provide good adhesion between the screws and the WPC panel.
If the screw loosens over time, you can take a small piece of PVC/WPC material, weld it with cyanoacrylate material, and screw it back in place! Maintenance of such WPC hardware is straightforward, and You can do it yourself.
The most crucial point in the above discussion is the “density” that people get confused with. Panel furniture can now be made with “screws and solvent”, but you can also make panel furniture without screws with “solvent welding”. This is a critical practice for the woodworking market. I’ve seen plumbers attach PVC pipe to another PVC pipe, but only with this solvent cement. Yes, the same thing happens with his PVC/WPC. Remember, these pipes hung from his first-floor terrace in his apartment for years. This means that density should only be considered for screw-on panel furniture.
To be clear — if you’re looking to make a small/medium size shoe rack, a 0.45 density solvent welded plate is perfectly fine, and you don’t need screws — no density concerns here. Closet drawers, small storage units, bathroom vanities, small chairs, and many pieces of furniture do not require structural strength. They can only be made with a specific gravity of 0.45 and solvent welding.
Yes, for large pieces of furniture. Cabinets, briefcases, and kitchen cabinets require structural strength, where WPC material with a density of 0.55 to 0.60 should be used with the screw and solvent method. Similarly, if the thickness is above 0.80, WPC door frames are also good choices. The higher the density, the higher the technical strength, the higher the compressive and tensile strength, and the higher the price.
Therefore, it is clear that the density of WPC materials should be determined according to the application and application. You and your carpenter friends should also be informed/educated about this so that you can technically use WPC material that is 100% termite and waterproof.
