Solid wood particle board
Solid wood particle board is a new type of high-grade environmentally friendly sheet, which is produced by the process of particle board.

Disadvantages: The use of chemical additives is less environmentally friendly. Poor moisture resistance and easy deformation.
3. Hexiang board

3, look at the environmental protection grade of environmental protection panels
Since July 1, 2002, the state has imposed restrictions on the release of formaldehyde in the board. For products that fail to pass the China Environmental Label Certification, if the formaldehyde emission can reach the basic requirements of E1 and E2, the products can also be listed. Sales, but E2 is limited to outdoor use. In this regard, consumers should polish their eyes.
