What is Sanded PVC Foam Board? What's It For?

Issue Time:2022/10/13
As an ideal alternative for wood panels (MDF, particle board or plywood), PVC foam board works well in furniture boards, decoration panels and display boards. To be used for these purposes, we often need to do some processing such as painting, pasting, and lamination to the PVC foam board. Then we must first ensure that the PVC foam board has a good surface suitable for these processing.

The surface of the PVC foam board is hard and smooth. We can directly paint, paste, and laminate on it, and we can also sand the surface to get better processing results.

Sanding Treatment

Sanding refers to the treatment of sanding the surface of the sheet. It is the main method of trimming the surface of the board and is a common processing method for woodworking. The purpose of sanding is to ensure the processing quality of the pasting or lamination. The surface of PVC foam board after sanding is matte, brushed and rough to the touch. 

For small size and small number of PVC foam boards, you may use sandpaper to sand the PVC foam boards. For our factory, we have a sanding production line that can automatically sand the PVC foam board with full size (1220x2440mm).

Why Sand the PVC Foam Board?

1. Reduce thickness tolerance
PVC foam board is a man-made board produced by extrusion process, which allows it to have a certain thickness tolerance. PVC foam sheets with a thickness of 5mm to 20mm often have a thickness tolerance of 0.2mm. Then we can reduce the thickness tolerance of the PVC foam sheet by sanding to obtain a uniform thickness.

2. Ensure the flatness of the substrate surface
For the PVC foam board with uneven surface or small defects on the surface, the surface can be trimmed by sanding.

3. Enhanced bonding strength
Last but not least, sanding gives the PVC foam board a rough surface. Greater friction allows the adhesive or paint to adhere more strongly to the PVC foam board.

But you may have such doubt: 

Will the strength of the sanded PVC foam board be diminished?

In our practical application, we found that the performance of the sanded PVC foam board is the same as that of the non-sanded PVC foam board.

For more scientific proof, we sent the sanded PVC foam board to SGS laboratory for physical and mechanical tests. The results show that the data of the PVC foam board after sanding are all within the standard value.
