From ancient times to the present day, wooden cabinets have always been a must-have item in every household. As time goes by, the emergence of a rich variety of high-quality wood panels has given traditional cabinets a second life, and cabinets with diverse styles have gradually become fashionable home items.
Although the good appearance of the board is an advantage, everyone should also pay more attention to its quality. If you choose a cabinet customized with inferior board, the adverse effects on your health will far exceed your imagination.
Adhesives, as an indispensable part of the board, greatly affect the quality of the board. Therefore, when choosing the board, the quality of the adhesive must be considered first to effectively avoid the minefield of inferior board.
Currently, the more common adhesives in board materials are urea-formaldehyde adhesive and MDI adhesive.
Urea-formaldehyde adhesives are primarily used in the board and interior decoration sectors. Composed of urea, formaldehyde, and water, urea and formaldehyde are condensed in the presence of a catalyst to form an initial urea-formaldehyde resin. This is then followed by the addition of a curing agent or additive to form an insoluble final resin adhesive.
At the same time, there is another adhesive favorite in the board industry - MDI glue, which is a downstream product of MDI (diphenylmethane diisocyanate) and has a wide range of uses.
After the boards are made, the difference between the two cannot be seen from the surface alone. So what is the difference between MDI glue and urea-formaldehyde glue? Let's take a closer look.
First of all, the material composition is different. Urea-formaldehyde glue is a resin adhesive made from urea and formaldehyde through a catalyst, while MDI glue is a high-molecular adhesion compound prepared from isocyanate. Compared with the composition of the two, MDI glue is more environmentally friendly. Secondly, the properties are different. After the urea-formaldehyde glue is cured, the glue layer is colorless, but it will release some free formaldehyde as the temperature changes, thereby polluting the environment; while MDI glue does not add additional formaldehyde during the preparation process, the volatility is extremely low, and the environmental performance is extremely high; from a cost perspective, urea-formaldehyde glue has a lower production cost than MDI glue; from the perspective of the scope of use, there are also great differences. Urea-formaldehyde glue is mainly used in the fields of board materials and interior decoration; and MDI glue, in addition to being used in the field of board materials, is also used in the chemical industry, light industry, transportation, medical care, aerospace and other fields. It seems that MDI glue is both environmentally friendly and has a wide range of uses, which is better than urea-formaldehyde glue!
Creating a healthy home and leading a quality life. We select high-quality wood and use safe and environmentally friendly MDI adhesive for bonding. Products currently using MDI adhesive include solid wood sliced OSB boards and LSB high-energy home boards. Healthy boards provide comprehensive care for your home environment.
Warm reminder: When choosing board products, you must consider environmental factors. Inferior board products are harmful to health and threaten life, and have a profound impact on the family. Only by choosing healthy, environmentally friendly and formaldehyde-free products can you truly ensure a safe and secure home environment!
