Speaking of polyurethane sandwich panels, the development in recent years can be said to have been very stable, and the entire market has almost reached a saturated state, so what is the difference between polyurethane sandwich panels and ordinary foam sandwich panels? What are the advantages of polyurethane sandwich panels?
Today, the editor will talk to you about the advantages of polyurethane sandwich panels. Before introducing the polyurethane composite board, I think it is necessary to talk about the insulation material first. The well-known insulation materials include polyurethane, polystyrene board EPS, extruded board XPS, foam board, etc. Their common feature is that they all have good insulation properties. Insulation effect, but the bonding performance of polystyrene board and extruded board is relatively average, and the flame retardancy/heat insulation performance is not good, so it can only be a transitional product.
Compared with the former two, rigid foamed polyurethane is an internationally recognized insulation material with better performance, and its performance indicators are superior to traditional XPS and EPS. It not only has good heat insulation, but also has strong adhesion. And it is convenient for continuous production, and the shape is beautiful. Moreover, it can also be combined with rock wool to make polyurethane rock wool board, combining the advantages of polyurethane and rock wool, the fire prevention effect is better.
