PVC foam board used for engraving should be rigid with fine and homogenous closed cell structure. That is why most customers choose PVC celuka foam board with 3mm thickness for engraving.
The shapes on the cabinet door or cabinet panel are usually processed by hot bending, using PVC celuka foam board thicker than 12mm.
Different from PVC celuka foam board, PVC co-extruded foam board is produced by two moulds at the same time, to say, one for core layer, the other one for two surface skins. So, it is likely that there will be some cracks between the core layer and surface skins under hot bending.
PVC co-extruded foam board is perfect fit for restaurants, buffet lines or cocktail parties due to its extruded rigid and smooth finishes on both sides.
