Why PVC edge banding?

PVC edge banding is mainly used for sealing the cross-section of the board, so as to protect the board from the environmental damage, especially for the damage of the water in the air. In addition, PVC veneer edge banding not only can prevent the volatilization of formaldehyde inside the board, but also achieving a beautiful decorative effect for the furniture.

What is PVC edge banding?

The main component of PVC is polyvinyl chloride. It is made of PVC resin as main raw material, adding suitable anti aging agent, stabilizer, calcium carbonate, CPE, dyed agent, epoxidized soybean oil and modifier. It can be divided into soft PVC and hard PVC.

 

The category of PVC edge banding

PVC edge banding can be divided into plain PVC edge banding and wood grain PVC edge banding.

 

About the plaint color

 

Plain color refers to the red, yellow, blue, green, etc. in daily life, which can be called plain color,the essence of it is single color.

 

The structure of the plain PVC edge banding

 

The upper layer is made of PVC material, and the bottom layer is made of the glue. It is relatively simple to use plain color edge banding board first, while the white panel is white edge banding strip, and so on. Generally, the color is different, so when adjusting the color, the manufacturer will ask the customer to provide the reference color, such as the panel sample, the panel color card, etc.

 

About the wood grain color

 

Wood grain color is the surface with paint printing paint, forming similar to the effect of the wood veneer lines.

 

The structure of the wood grain PVC edge banding

 

The middle layer is PVC base material, the surface layer is paint printing, and the bottom layer is primer.

 

So the price of the wood grain edge banding is higher than that of the plain edge banding slightly.

 

The advantages of the PVC edge banding

 

  • PVC edge banding is light, comparing with the metal and plexiglass. The reason why it is light is not because it is a high molecular compound, but because it is an organic compound, which is composed of light elements such as carbon, hydrogen, oxygen and nitrogen。

 

2、The material of PVC edge band is plastic, which is easy to process. Plastic has plasticity, which means deformation after heating or pressure, and maintain its original shape after cooling or pressure disappearing. It can be processed into different shapes by extrusion, such as T-shaped, H-shaped, D-shaped, V-shaped, I-shaped, etc.

 

  • PVC edge banding has high quality and low price, and the price changing of plastic is  less than that of metal.

 

4、Plastic doesn’t easily to decay or rust. However, this feature also brings a serious problem to human beings: because plastic is not easy to decay, a large number of plastic wasted can not be absorbed and decomposed by nature, which results in a certain degree of environmental pollution.

What is the PVC edge banding? How to Choose qualified PVC edge banding?

What is the PVC edge banding?

PVC edge banding is one kind of thermoplasticity coiled material made by the polyvinyl chloride in the way of calender by mixing up with the auxiliary, such as the plasticizer, stabilizer, lubricant, and the dye.

The PVC edge banding is always used with furniture contact paper, to decorate a better overall effect of furniture. In the furniture decoration market, the wood grain furniture paper is one of the popular contact paper, so the popular PCV edge banding is wood grain edge banding too, especial for maple edge banding and walnut edge banding.

The advantages of the PVC edge banding

1、Soft surface, although the surface was printed the wood、marble and the cloth texture on the surface, it still could keep the surface soft.
2、Having the realism and the third-dimension as the real wood.
3、Having a certain degree of the cleanliness feature and the decorative feature.
4、Having certain degree of heat resistance, chemical resistance, and corrosion resistance.
5、Having certain degree of solidity on the surface.

The main function of the edge banding.

1、Banding the panel section to avoid the damage caused by some negative elements in the environment and the using process (pay more attention for the water).

2、Avoid the volatilization of the formaldehyde hiding in the panel to achieve the function of decorative feature.

About the calcium carbonate powder (usually be called lime powder)

Generally, there is some calcium carbonate in the PVC edge banding. And the content of the calcium carbonate powder should be kept in an appropriate quantity. If it too high which will make the structure of the PVC loose and affect the quality of the PVC edge banding heavily, causing a lot of problem, such as

1、Crease in white.

It means that the edge banding is flexed in arc-shaped which will caused the white crease. Once the white crease caused and it will not disappear, even through the edge banding is straightened again.

2、Edge curl

It means that handling the detail about the edge banding will cause a gap, producing the edge curl. There is no doubt that edge curl also caused by other situation, take a example, the different of the speed and the order of adding the hot melt adhesive and raw material will not make the edge banding attaching on the panel tightly which lead to the edge curl appearing。

3、Poor appearance with the dim glossiness

After the edge banding is cut in detail and polished. The glossiness of is will become dim and fuzzy, leading to the appearance poor. At the present market, a lot of manufactures will add more calcium carbonate powder. Sometimes the content of the calcium carbonate powder will even over 60%. And the reason for why dose the different type of edge banding with the same brand sell in different price, the key reason is the content of the calcium carbonate powder.

4、Cracking

Due to the high content of calcium carbonate, the edge band has no toughness, and the internal structure will be loose. If it is affected by external force slightly, it will crack, especially in the transportation with low temperature.

5、The problems in surface printing

There are two technologies for surface printing: printing and heat transfer film. The surface of heat transfer film is glossy, and the product looks bright and layered. Then due to its high cost, slow transfer speed and inconvenient color assortment with the panel, it has been replaced by printing. However, some low quality PVC edge banding is added in excess calcium carbonate powder, which makes the problem about discoloration, whatever which printing technology we choose, the discoloration still can not be handled，so the technology of heat transfer film also be choose some time.

How to find the qualified PVC edge banding.

The notes of purchasing on PVC edge banding

A: Slide surface with no bubbles，no lines and temperate glossiness.

B:Both the surface of it should keep the same degree of flat, thickness and width.

C: Equitable hardness with higher elasticity, better quality and stronger wear resistance

D: After handing, the side color of the edge banding should be similar with the color of the surface. And we should make sure that the degree of the whiteness should not be very obvious, at the same time it should have a slight glossiness, if not the PVC edge banding must be made up by the low-quality materials, which will lead to the color of the furniture become inharmonious.

E: The treating agent of the back surface should be uniform. In general, the transparent and white treating agent is well. And if the back is not handled properly, it will lead to low bonding strength after edge sealing, or even can not be bonded.

F: The color of each batch of edge banding must be consistent. The smaller the color difference of different batches, the better the quality

G: The edge is cut off with flexibility and no cracking.

H: The transparent sealing glue (adhesive paper used for sealing carton) is pasted on the sealing edge. Rub it back and forth for several times with your finger at the position where the sealing glue is pasted, and then pull it to test whether there is discoloration in the edge banding.
