What Are The Advantages Of Polyurethane Sandwich Panels?
When it comes to polyurethane sandwich panel, it can be said that the development of these years has been very stable, and the whole market situation is almost saturated, so what is the difference between polyurethane sandwich panel and ordinary foam sandwich panel? What are its advantages?
Today I will talk to you about the advantages of polyurethane sandwich panels. In the introduction of polyurethane sandwich panel before, I think we need to talk about insulation materials, we are more familiar with the insulation materials are polyurethane, polystyrene board EPS, extrusion board XPS, foam board, etc., their common feature is that they all have a good heat preservation effect, but polystyrene and extruded plastic board bonding performance is relatively general, and flame retardant/heat-insulating properties are also not good, so it can only be a transitional product.
And rigid foam polyurethane compared to the first two, it is internationally recognised as a better performance of the thermal insulation material, the performance indicators are better than the traditional XPS, EPS, not only good thermal insulation, strong adhesion, and easy to continuous production, moulding beauty now. And it can also be rock wool composite made of polyurethane rock wool board, combined with the advantages of polyurethane and rock wool, fire prevention effect is better.
