Polyurethane rigid foam: rigid foam plastic, which is composed of A component and B component mixture, has the functions of thermal insulation and insulation. It is called rigid polyurethane foam, or polyurethane rigid foam. Component a material: component a material refers to the composite material composed of composite Polyols (composite polyether or polyester) and foaming agents and other additives, commonly known as white material. Component A is one of the necessary raw materials for forming polyurethane rigid foam. Component B material: component B material refers ...

The pu insulation board production line mainly includes three parts: molding machine, foaming machine and laminating machine. During production, the steel coil is expanded into the profiler, cut off after being profiled, placed manually to form a closed body with the bottom plate + upper plate + four building laminator, then compressed through the roof mechanism, and then injected into the PU foaming machine for molding. Two boards are foamed, injected and solidified on site, while the other two boards are loaded and unloaded, so they are imported and exported. Process Descrip...
