PVC共挤发泡板内外层为硬质PVC，芯层为PVC发泡层，能大大降低设备成本和配方成本（和真结皮发泡设备相比)，产品质量和各方面参数都接近或优于真结皮发泡板（1.22m制品宽，5~20mm厚，密度~O.5g/cm，表面强度:50~75洛氏硬度），同时制品表面可经过烫印，印刷或贴膜，获得不同样式和图案，此外在有些需要折边的应用场合，经过热弯曲处理可以达到应用要求。
设备组成;由挤出机，分配器，模具，定型模板，冷却架，牵引机，切割机，堆料台组成，设备精度高，操作方便。
Structure of the PVC foamed board extrusion line: Outer surface layer is rigid PVC and inner layer foamed PVC, it feature in low machine andformula cost compared with PVc skinned foamed plate, meanwhile, the product and paramelers( 1.22m width with 5-20mm thicknessproduct dimension, -0.5glcm3 density 50-75 Rockwell hardness) are all qual of better.Aiso,the surface of the product can be printed orlaminated to get different patterns.
The machine consists main extruder & co-extruder, distributor, calibrator moulding block,cooling rack, haul off cutter & stacker.
