Phenolic tunnel insulation board is made of one side of the phenolic board compounded with high-quality reinforcement aluminum foil and the other side compounded with Kraft paper. The covering material can be customized, and the thickness can be customized to 10mm-230mm. The tunnel insulation phenolic board has the following performance advantages: 1. Good thermal insulation performance: the thermal conductivity of the tunnel insulation phenolic board is ≤ 0.025w/m · k, which is very suitable for the fields with high thermal insulation and energy conservation requirements; 2. High flame retardancy: good heat resistance, good flame penetration resistance, non flammable when exposed to fire, non melting and non shrinking, no dripping objects, no shrinkage deformation, and low smoke content at high temperatures; 3. Not easily deformed: very stable performance; 4. Fluoride free, it is a green and environmentally friendly building material. The foaming process does not use chlorofluorocarbons, the ratio is reasonable, the reaction is complete, and the formed compound has no residual toxins; 5. Tunnel engineering is the connection between phenolic composite panels and tunnel walls, and the use of tunnel insulation phenolic panels is more stable and less prone to detachment.
