Adding melamine board in the high end wardrobe can effectively prevent the environmental pollution caused by formaldehyde and urea formaldehyde resin as a preservative. In addition the melamine board can replace wooden plate, aluminum plate made of mirror, high wear resistance, anti-static, relief, metal finishes.

Melamine board, the pavement in the shaving board, damp proof board, medium density fiber board or hard fiber board surface, after hot pressing and into the decorative board. In the production process, usually by the number of layers of paper combination, the number of the layers according to the requirement.

The inner structure of the medium density board is uniform, the binding force is larger than that of the particle board, the deformation is small, the surface is smooth, and the nail holding power is strong. Therefore, the melamine board made of medium density board is more solid and durable, can play the characteristics of the assembly type furniture assaembly.
