PVC共擠發泡板內外層為硬質PVC，芯層為PVC發泡層，能大大降低設備成本和配方成本（和真結皮發泡設備相比)，產品質量和各方面參數都接近或優于真結皮發泡板（1.22m制品寬，5~20mm厚，密度~O.5g/cm，表面強度:50~75洛氏硬度），同時制品表面可經過燙印，印刷或貼膜，獲得不同樣式和圖案，此外在有些需要折邊的應用場合，經過熱彎曲處理可以達到應用要求。
設備組成;由擠出機，分配器，模具，定型模板，冷卻架，牽引機，切割機，堆料臺組成，設備精度高，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.
