Eva, pur, and laser are three different edge banding processes, eva and pur are edge banding processes named after edge banding glue, laser is an edge banding process named after edge banding form, abs and pvc are commonly used edge banding strips of two materials.
Most of the edge banding on the market are made of PVC material, because PVC edge bandings are cost-effective and stable in performance, but ABS edge bands are better in color than PVC edge bands, which means that the edge banding effect is more beautiful , so the price of abs edge banding is more expensive. Many custom factories will choose abs edge banding in order to maximize the details.
EVA hot melt adhesive
The most common edge banding process, the glue used is eva hot melt glue, which is solid at room temperature and needs to be melted in a glue pot at high temperature before it can be used.
The advantages of this eva hot melt adhesive are high cost performance and simple processing
The disadvantage is that the glue line is very thick and not beautiful.
In addition, it is very troublesome to clean the glue pot, but now many eva edge banding machines have double glue pots, one glue pot for light-colored glue, and one glue pot for dark-colored glue. According to the depth and light color of the board, the glue pots are used interchangeably. The glue in it can effectively avoid the defect of thick glue line.
The edge banding process of eva can use ABS and PVC edge banding materials. Both side strips have high cost-effective properties, and they can better control costs when combined.
what is pur
Pur is an irreversible edge banding process. Irreversible means that the glue cannot be reused. Pur is also a hot melt adhesive. It is very different from EVA in the principle of pasting. Pur glue has a chemical reaction with water in the air after melting. A new substance is generated, and once solidified, it cannot be used again, which is why it is irreversible.
Pur is not used in a glue pot, but in a special hot-melt machine. The advantages of the pur edge banding process are less glue, thin glue lines, firm edge banding, irreversibility, and good water resistance. The disadvantage of the pur edge banding process is that The production environment is very picky, and it is precisely because the pur edge banding process has high requirements on temperature, humidity, and air quality in the production process. Many factories do not have such production conditions, so the pur edge banding process is not popular. The eva is high, still belongs to the high-end field, and the pur edge banding process is also compatible with the edge banding strips of two materials, pvc and abs.
What is laser edge banding process
The laser edge banding process is the best edge banding process at present. There is no need for edge banding glue at all. The working process is to use a laser to scan the back of the laser special edge banding strip at high temperature to melt the adhesive on the edge banding strip, and then Paste directly to the board to complete the edge banding.
The advantage of the laser edge banding process is that it can achieve seamless edge banding, but the disadvantage is that the edge banding machine and edge banding strips are expensive.
To sum up, laser edge banding price is the highest, the effect is the best, and there is no glue line on the edge banding;
PUR edge banding price is moderate, and the price is also in the middle, the glue line on the edge banding is very thin, and if it is the same color glue, basically no glue can be seen eva edge banding has the lowest price and the worst effect, and the glue line at the edge banding is relatively thick.
