There are many popular PVC foam boards in the market. If you buy poor quality PVC foam board, then we process the finished product into a substandard product, which will bring economic losses to the enterprise. How to correctly go to buy quality PVC foam board?

Observe the surface of the foam board

1. Look at the color of the surface of the PVC foam board. If the PVC foam board surface color yellowing, or impure color with other miscellaneous colors, then the foam board in the formula must be a problem, or the production process is not. If used for advertising printing, the effect of printing out will be greatly reduced. Therefore, be sure to choose pure color, no color difference of PVC foam board.

2. observe the cross-section of the PVC foam board has no air holes. Normal PVC foam board cross-section is uniform and dense tiny voids in the honeycomb. If the cross-section of the PVC foam board has large pores, then the foaming of this foam board is certainly not uniform. This is a poor production process. It will also produce bubble holes in the inner part of the board, that is, in the middle. Then, the force of this poor quality foam board will not be uniform, it is easy to make a place deformation or fracture.

3. PVC foam board surface has more mechanical patterns. The more shallow and inconspicuous the mechanical pattern, the better the product.

Smell

The quality of PVC foam board should have no smell. If you smell a very pungent smell with your nose, it means that the board contains environmentally unfriendly substances, try not to use it.

Tactile sensation

1. Feel the surface hardness of the PVC foam board. If used for furniture production and other surface requirements are high, it should be difficult to scratch the mark with a fingernail. 3.2.

2. Carefully touch the surface of the plate. Whether it is flat. There are no fine lines.

Inspection

1. Measure the thickness of the eight PVC foam sheets. Because the uneven thickness of PVC foam board will cause trouble to our secondary addition, such as the wrong size in some places. Therefore, we must measure the thickness of its eight parts is not the same, which eight parts? The four corners plus the middle part of the four sides.

2. Take the sample to fall. Easy to break is generally a high calcium product. Of course, to meet your requirements if the price is right is possible.

3. Take the sample and step on the side of the plate with your foot to see if it can be cracked. Or the elongation at break after cracking.

4. The direct way to judge the degree of weathering is to get a high temperature and high light place for a few days to see the rate of change of the surface, but too waste of time.
