Difference Between Rigid and Free foaming PVC Foam Board

The PVC foam board, as we know, can also be called rigid PVC microporous foam material, which can be divided into PVC free foam board and PVC crust foam board according to different production processes. In fact, the difference of these two production lines only lie in the extrusion foaming process.

⑴Free-foaming: Free-foaming means that the melt expands freely as soon as it leaves the die, and immediately, it enters the larger calibration device. Free foaming causes all cells to be formed on the cross-section of the extrudate, and the growth of surface cells is restricted by cooling, and finally a product with continuous density, moderate hardness and smooth surface is formed. The advantage of this method is that the process is simple, and is suitable for producing products with a thickness of 2-6mm, simple geometric shapes, and matte surfaces (such as pipes, sheets and profiles with simple geometric shapes).

⑵Inward-foaming method,which can be called crust foaming method or Celuka method (Celuka method). is a special die with a core inside used to divert the plasticized material. The calibration device is connected very closely with the die, and its outer contour is the same as the die. When the material is fed into the sizing sleeve before the entrance of the mold, the melt containing the foaming agent enters the cooling sizing sleeve as soon as it leaves the mouth film, and undergoes rapid cooling on the entire surface, thereby preventing the formation and extrusion of surface cells from any swelling in the cross section of the object. Thereby forming a skin layer on the surface cooling. At the same time, the core in the die makes the cavity created in the semi-finished product filled with the foam formed by the remaining melt, which means a process foaming inside. By controlling the cooling intensity, products with a surface layer thickness of 0.1-10mm and a product wall thickness greater than 6mm can be obtained. This method can produce profiled materials with complex cross-sectional shapes, and the products have the characteristics of smooth surface, high hardness, and low core area density. In addition, by combining the method and method ①, a product can be obtained with a skin on one side and a free state on the other side.

PVC Crust Foam Board Machine List

Application Field 

PVC foam board,also known as Chevron board and Andy board, having two types: crust foaming and free foaming. PVC foam board is widely used in passenger car, train car roof, box core layer, interior decoration board, building exterior wall board, interior decoration board, office, residential, public building partition, commercial decoration frame, dust room boards, ceiling boards, screen printing, computer lettering, advertising signs, exhibition boards, sign boards, photo album boards and other industries and chemical anti-corrosion engineering, thermoformed parts, cold storage boards, special cold insulation engineering, environmental protection molds, sports equipment, breeding materials, seaside moisture-proof facilities, water-resistant materials, art materials and various lightweight partitions instead of glass ceilings. It has a wide range of uses and is increasingly popular with the public due to its relatively low price and superior performance.
