Raw material

Wear-resistant layer: Aluminum trioxide transparent paper or silicon carbide transparent paper, fire resistance and wear resistance mainly depends on this layer of paper.

Decorative layer: Melamine impregnated printing paper, the weight of general paper: 80-120 g/.

Base layer: kraft paper impregnated with phenolic resin or urea-formaldehyde resin. The weight of general paper is 140-180 g/. The thickness of fire-proof board mainly depends on the thickness of the basement layer. The more the basement layer, the thicker the fire-proof board.
