Analysis of the advantages of polyurethane board

Polyurethane sheet is a new type of energy-saving thermal insulation product with superior thermal insulation, fire resistance and flame retardancy, which can be widely used in cold storage, large and medium-sized chemical facilities, grain depots, various pipeline thermal insulation and waterproof projects, and external wall thermal insulation projects. Using polyurethane sheet as wall insulation material can reduce wall thickness and increase indoor use area. In terms of environmental protection and energy saving, according to the requirement of 50% energy saving in civil buildings, 17 kg of standard coal can be saved per square building area in each heating period.
Rigid polyurethane is fireproof, flame retardant and high-temperature resistant. After adding flame retardant, polyurethane is a flame retardant self extinguishing material. Its softening point can reach more than 250 ℃, and it will decompose at higher temperatures. In addition, polyurethane will form ash on its foam surface when burning, which helps to isolate the foam below. It can effectively prevent the spread of fire.
