With the development of the construction industry, more and more new building materials appear, so which material is more popular? It is not difficult to find that 4x8 pvc foam sheet is popular with everyone, mainly because this material is a kind of A relatively new type of material has many advantages both in the entire production process and the processing process.

The popularity of PVC is also due to its characteristics.

Then look at the performance of PVC (with rain resistance, fire resistance, anti-static, easy to shape), the second is the low input and high output characteristics of PVC. So, why does PVC have two major advantages? Let's take a look at its production process.

The production process of PVC is not complicated. The ordinary production line generally consists of a roller press, a printing press, a back coater and a cutting machine. For the film from 0.3 mm to 0.7 mm, it is produced and printed on the front side of the film by a printing machine, and a layer of back coating is attached to the back of the film by a back coater. Don't underestimate this back coating, it is an important guarantee for the performance of the PVC film. The back coating is composed of special materials and is a high-energy affinity agent. It is precisely because of this back coating that the PVC film can be tightly fused with the medium-density board or other boards, and it will not be glued for ten or fifteen years. The problem with ordinary face masks is that they cannot solve the problem of film shedding. Since the whole production process is carried out at high temperature (the temperature in the rolling machine reaches 220 degrees), this makes the PVC film have high light resistance and fire resistance, and ensures the high quality of the PVC film.

The production process of PVC has attracted much attention in industries other than construction. I believe that PVC foam board will have a better development prospect.
