How to choose EVA edge-banding hot melt adhesive is a question that many furniture manufacturers and woodworking adhesive traders are very concerned about. As the degree of intelligentization of furniture manufacturing becomes higher and higher, this will be related to the production efficiency, edge-banding effect, product cost, etc. Next, we will share with you how furniture manufacturers can choose the appropriate EVA edge-banding hot melt adhesive from multiple dimensions of edge-banding hot melt adhesive.
What is EVA edge banding hot melt adhesive?
EVA edge-banding hot melt adhesive is a solvent-free, water-free, 100% solid fusible ethylene vinyl acetate polymer. It is solid at room temperature and becomes a liquid furniture edge-banding adhesive that can flow and has a certain viscosity when heated and melted to a certain degree. It is brown, translucent, or white after melting. The main component of the EVA system hot melt adhesive is ethylene and vinyl acetate copolymerized under high pressure, and then made with tackifiers, viscosity regulators, antioxidants, etc.
What is the use of Eva edge banding hot melt adhesive?
In furniture manufacturing, edge banding hot melt adhesive is mainly used for edge banding of furniture to make it more beautiful, strong, and moisture-proof. Specifically, edge banding hot melt adhesive can be used to bond pvc edge banding, pet edge banding, abs edge banding, veneer edge banding, and paper edge banding on the edges of particleboard, medium fiberboard, multilayer board, solid wood board, and other wood materials.
Why do furniture manufacturers choose hot melt adhesive for edge banding?
With the continuous exploitation of wood, the price of wood has increased yearly, resulting in a constant increase in the cost of solid wood furniture. This is also the main reason why more and more furniture manufacturers and consumers choose panel furniture. Compared with solid wood furniture, panel furniture has more fashionable colors and shapes, and is deeply loved by young people.
From the perspective of furniture manufacturers, panel furniture can be produced using a fully automated production line, and the production efficiency is much higher than that of solid wood furniture. The above three factors (cost, recognition, and production efficiency) have led more and more furniture manufacturers to choose edge banding hot melt adhesives.
What color is Eva edge banding hot melt adhesive?
Conventional edge-banding hot melt adhesive is light yellow or white, but many hot melt adhesive manufacturers add pigments to the hot melt adhesive to change it to black, brown, pink, red, yellow, and other required colors to match the color of the furniture board and avoid the glue line affecting the overall aesthetics after the board is edge-sealed.
The “traceless glue” often mentioned by customers is a hot melt adhesive with 100% resin content. The characteristic of this edge-banding hot melt adhesive is that the glue line is transparent, but the overall strength is slightly worse than that of conventional edge-banding hot melt adhesive. Color is also one of the factors in choosing edge-banding hot melt adhesive.
What factors should be considered when choosing EVA edge banding hot melt adhesive?
1. Board
The board that can be bonded with conventional EVA edge-banding hot melt adhesive include particleboard, medium-density fiberboard, multilayer board, solid wood board, etc. Different boards have different requirements for hot melt adhesive, and the density of the board and the permeability of the glue should be considered. If the selected board has loose pores and low density, the amount of glue applied should be appropriately increased to avoid the situation where the hot melt adhesive is completely absorbed by the board, resulting in a lack of glue between the board and the edge banding.
2. Edge banding strip
The materials of the conventional EVA edge banding hot melt adhesive include PVC, PET, ABS, solid wood veneer, paper, etc. The permeability and wettability of the hot melt adhesive to the edge banding of different materials are different. Therefore, before choosing the edge banding hot melt adhesive, the furniture manufacturing factory must communicate with the glue supplier about the material of the edge banding to be bonded.
3. Types of furniture
At present, the types of furniture that use EVA edge-banding hot melt adhesive include office desks, cabinets, wardrobes, doors, etc. The main difference is that the corresponding boards and edge-banding widths and thicknesses of different furniture types are different. Just like the width and length of wooden doors are longer than those of conventional furniture, there are requirements for the wettability and melting speed of edge-banding hot melt adhesive. Therefore, manufacturers need to know in advance whether the edge-sealed furniture is straight edge-sealed, curved edge-sealed, special-shaped edge-sealed, etc.
4. Types of edge banding
According to the furniture production efficiency of each factory, the types of hot melt adhesive edge banding are divided into manual edge banding, machine semi-automatic edge banding, and machine fully automatic edge banding. Manual edge banding requires a longer curing time for the edge banding hot melt adhesive. Manufacturers that choose fully automatic edge banding machines are all factories with complete production lines. The process of cutting, edge banding, cutting, punching, packaging, etc. is integrated. In order to ensure the high efficiency of the product production process, the curing time of the edge banding hot melt adhesive is very short, and the requirements are much higher than those of ordinary hot melt adhesives.
5. EVA content ratio
The EVA (ethylene-vinyl acetate copolymer) content ratio in the edge-banding hot melt adhesive is related to the adhesive strength and wetting performance of the glue. Generally, the EVA content is between 30% and 70%. The higher the content, the higher the adhesive strength of the hot melt adhesive. However, the higher the EVA content ratio in the edge-banding hot melt adhesive, the higher the price. When choosing, manufacturers should consider their production needs to choose glue, after all, this is related to the cost of furniture.
In summary, when choosing EVA edge-banding hot melt adhesive, factors to consider include: board, edge banding strip, type of furniture, type of edge banding, EVA content ratio, hot melt adhesive color, etc. I hope this article will be helpful to you.
