What Is A Pu Foam Spray Machine?
A Pu Foam Spray Machine is a specialized device used to spray polyurethane foam onto surfaces. It mixes two liquid chemicals in a 1:1 ratio to create foam insulation. This foam expands quickly and sticks to surfaces, creating a solid, sealed layer. The machine is widely used for insulation, waterproofing, and filling gaps.
