Vacuum-pressing doors, cabinets, and wardrobes are very popular among young people because of their fashionable and novel styles. These furniture are produced by furniture factories using vacuum pressing glue to blister PVC skin. Even though many factories have been using this glue, they are still unclear about the purpose, chemical principle, and process principle of vacuum pressing glue. Next, let’s share with you what vacuum pressing glue is from multiple perspectives:
1. Product Uses of Vacuum Pressing Glue
Vacuum Pressing Glue is an adhesive used to heat-absorb and bond the flat surface and shape of the board with the PVC film in a vacuum environment. The boards for blistering are mainly density boards, particle boards, etc.. In contrast, the materials for blistering are mainly PVC films, veneers, etc.
The products of Vacuum Pressing Glue have a wide range of uses. In addition to conventional wooden doors, cabinets, wardrobes, audio boards, etc., vacuum blistering glue is also used for computer desks and car consoles. For products using blistering technology, there is no need to spray paint in the later stage. It is precisely because of the reduction of paint that the products will be healthier and more environmentally friendly, so they are also loved by many consumers.
2. The chemical principle of vacuum pressing glue
From a chemical perspective, vacuum pressing glue is a mixed environmentally friendly adhesive made from EVA emulsion and PUD polyurethane. It has the advantages of being safe, environmentally friendly, having no irritating smell, and containing no formaldehyde. The hardness of the product can be adjusted, and a curing agent can be added and mixed (to improve the product’s bonding strength and high-temperature resistance). It is precisely because of these advantages that vacuum pressing glue has been unanimously recognized by furniture manufacturers.
3. The process principle of vacuum pressing glue
From the operation process, vacuum pressing glue softens the PVC film and removes the air inside by heating and vacuuming the vacuum forming machine, ensuring that the blister material can fit tightly on the board. After the vacuum is removed, the glue forms an adhesive force, which tightly bonds the PVC film to the board. Therefore, the temperature setting of the equipment, the vacuum setting, and the adhesive force of the glue all play a crucial role in the final effect of the furniture product.
