PVC Edge Banding Formula And Problems

PVC edge banding formula and problems

The base material of PVC edge banding is composed of PVC resin, calcium carbonate powder and various auxiliary materials (stabilizer, DOP oil, ACR, stearic acid, carbon powder, toner, anti-aging agent, etc.). The sealing edging effect is related to the proportion of the base material raw materials. Let's learn about the formula of PVC edge banding and the problems that may arise!

Melamine seals, commonly known as stickers, have the advantages of being easy to stick and not easy to stretch and deform when exposed to cold or heat, but due to their brittle and easy to break, they are prone to collision during the production and transportation of furniture.

Advantages of PVC edge banding

1. The edging of PVC edge banding furniture is very light, which is for metal and plexiglass. The reason for its lightness is not because of polymer compounds, but because of organic compounds, that is, carbon, hydrogen, oxygen, nitrogen and other light elements.

2. The edging material of PVC edge banding furniture is plastic, which is easy to process. Plastic is plastic. In other words, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. Through extrusion and other methods, it can be processed into T-shaped frames, H-shaped frames, D-shaped frames, V-shaped frames, and Chinese characters.

3. The stickers of PVC edge banding furniture are of good quality and cheap, and the price fluctuation of plastic is not as large as that of metal.

Judging the quality of PVC edge banding

1. From the perspective of the hue and surface roughness of the frame, the color of the surface of a good frame is also very important. Is the color close to the customized product and is bright. If the surface is rough and there are traces of pulling, then the quality is definitely everywhere. This is the problem of the surface quality of the seal. It has little to do with the quality of the inner material of the edge banding, but mainly the production technology of the edge banding factory and the production technology skills of the employees. A good edging should have a smooth surface, no blistering or less blistering. No attraction or less attraction. The gloss is moderate, not too bright or matte. Unless there are special requirements.

2. Check the flatness of the surface and bottom of the border strip, and whether the thickness is uniform. Otherwise, the joint and glue between the edging rod and the board will be too prominent, and the gap between the board and the edging rod will affect the overall appearance. Details determine success or failure, and it is often a small detail problem that may lead to an embarrassing situation where the overall effect cannot be achieved.

3. Whether the frame looks white, whether the surface of the bent frame looks white, and whether the frame base color is close to the color of the board surface. PVC sealant is mainly made by adding additives to PVC and calcium carbonate. When the calcium carbonate content is too high, the sealant sometimes turns white and sometimes turns white when broken, proving that these products are of poor quality.

4. Is the strength okay and is it elastic? Strong and expensive means good wear resistance, and correspondingly good quality. Excessive strength also means increased processing difficulty. Low elasticity means low wear resistance and poor anti-aging ability. In addition, according to actual production needs, if manual edging is generally required, soft points can be made appropriately, and automatic edging machines can make hard points appropriately.

5. Whether the back rubber is evenly attached or easy to fall off during use.

6. Smell the PVC edge banding. Products made with high-quality raw materials generally have little odor. If the smell is too strong, the quality of the raw materials used in production will be very poor.
