Polyurethane sandwich panel is a new type of green environmental protection building materials. Application in some developed countries has gained popularity, as a kind of excellent energy-saving insulation products, depend on the advantage of insulation, fire prevention, it provides effective solution for the crisis of china’s energy consumption. More and more people are using, there is a problem that how to extend the service life of polyurethane composite board. Below we look at together.
First, waterproof, breathability of freezing thawing.
Polyurethane sandwich panel insulation system has a good waterproof performance, it can effectively prevent the erosion of the rain cause the wall erosion. It get the test results by anti-crack mortar of polyurethane composite panel. After freezing thawing thirty times alternation, the performance has no obvious decrease.
Second, the fire prevention performance.
In the process of foam products add the efficient flame retardants. It will form a coking thermal insulation layer at the time of fire, keep high temperature to not melting, no flowing inhibit the spread of the burning, there is result that improve fire prevention ability of the overall building.
Third, good overall performance, anti-collision crack.
Polyurethane sandwich panel using anchorage and adhesive fixed products on the wall. A layer plaster mucilage in Outside, after the complete construction, it can form an organic whole, and reduce the wall cracking. To prevent impact damage in a certain degree, reduce the risk of system deformation to cause cracking.
Hope that the above information on polyurethane sandwich panel can bring you help.
