1.Environmental protection grade of melamine board
The environmental grade of melamine board is the environmental standard of Europe. There are three levels from high to low are E0, E1 and E2, and the corresponding formaldehyde limit level is also divided into three levels: E0, E1 and E2. For each kilogram of board, the formaldehyde emission level of E2 level is less than or equal to 5 mg, the formaldehyde emission level of E1 level is less than or equal to 1.5 mg, and the formaldehyde emission level of E0 level is less than or equal to 0.5 mg. It can be seen that the one reaching the E0 level is the most environmentally friendly melamine board.
2.Fireproof grade of melamine board
Melamine board has a certain fire resistance, that is, fire protection. Its veneer is the decorative paper which is soaked by the melamine adhesive and be dried. Finally the melamine board is made by hot pressing together with the substrate and veneer . Melamine board has advantages of large hardness, wear-resistant, good heat resistance and resistance to ordinary acid and alkali alcohol. But because the ordinary melamine board has no fireproof particles, the fire rating is not so high.
3.Moisture proof grade of melamine board
Melamine board was added a certain proportion of moistureproof particles in the base material production process which can greatly reduce the probability of water expansion of the board. Melamine board is lightweight, mildew proof, moistureproof and waterproof. It is a good damp proof board for indoor and outdoor decoration, and its moistureproof grade is very high.
