Many people know PVC foam board, but PVC foam board is divided into PVC celuka foam board and PVC co-extruded foam board. What is the difference between the two? Here are a few points for you to summarize:
1.PVC celuka foam board generally refers to PVC celuka foam board, while PVC co- extruded board is a board extruded by co-extrusion of two or more different materials or materials of different colors.
2.The PVC celuka foam board is extruded by a single main machine; the PVC co- extruded board is extruded by a double-head core layer and a skin layer through a die at the same time, the middle thick foam surface layer is not foamed, and its hardness is higher than PVC celuka foam board.
3.PVC celuka foam board is divided into micro celuka foam and high celuka foam, the density of micro celuka foam is 0.4, the density of high celuka foam is 0.45-0.7; the density of PVC arch extrusion board is 0.45-0.7 Density and overall strength are higher than ordinary PVC celuka sheets, and the skin is harder and more resistant to aging than the skinned sheets.
