Polyurethane composite board is a kind of composite board. Now it has a wide range of applications. It can solve all the problems of service life, earthquake resistance, fire protection and heat preservation that people are worried about.

Let's look the advantages of polyurethane composite panels.

6. Good impermeability, moisture-proof and waterproof: Polyurethane is a hydrophobic material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not leak water. Pu rigid foam is a dense microcellular foam with a closed cell rate of more than 92%. It has a smooth self-skinning and is an excellent impermeable material. The direct spray molding technology is used during construction to make the overall formation of the board more complete. Water impermeable. The Pu hard foam layer can be firmly bonded to the base layer, and its bonding strength exceeds its own tear strength, so it has better water impermeability.
