High-density board and particleboard have high formaldehyde content.
The formaldehyde content of qualified density board and particleboard meets the national standard, and there is no difference between high and low.

According to the different density, it can be divided into high density board, medium density board and low density board. Dense density board is a good material for making furniture abroad because of its soft texture, high impact strength, uniform density after pressing and easy to reprocess, but its disadvantage is poor waterproof. Medium and high density board is made by grinding small diameter wood, adding glue and pressing at high temperature and high pressure.

Solid wood particle board is an artificial board made of wood, wood poles and logs, with fine wood fibers on both sides and long wood fibers in the middle, which is glued by heat and pressure after being coated with adhesive. The panel is decorated with melamine and the cross section is honeycomb. Solid wood particleboard, as a new, high-grade and environmentally-friendly substrate, has been widely used by European and American furniture manufacturers and also in the domestic high-grade panel furniture market.

Extended data

High-density fiberboard is compatible with all the advantages of medium-density fiberboard because of its excellent physical properties. It is widely used in indoor and outdoor decoration, office, high-grade furniture, acoustics and interior decoration of luxury cars, and can also be used as production materials for anti-static floors, partitions, security doors, wallboard and partition walls of computer rooms. It is also a good material for packaging.

In recent years, instead of high-grade hardwood, it is directly processed into composite floor and strengthened floor; It is also used in cargo protection frames during transportation and modern decorative frameless paintings. For example, the frameless picture of visual life with a national registered trademark is applied in this way, making home life more environmentally friendly. Generally, custom-made furniture mostly uses high-density boards.
