XPS plate has dense surface layer and inner layer of closed pore structure. Its thermal conductivity is much lower than that of EPS with the same thickness, so it has better thermal insulation performance than EPS.

 

 

 

Light texture, easy to use: the complete closed cell foaming chemical structure and honeycomb physical structure of XPS board make it light and high strength, easy to cut and transport, not easy to be damaged, and easy to install. Mechanical fixings shall be used for the fixation of extruded polystyrene and base wall. Construction can be carried out as usual in winter.

 

 

 

Good stability and corrosion resistance: in long-term use, it does not age, decompose or produce harmful substances, its chemical performance is extremely stable, it will not degrade due to water absorption and corrosion, which will degrade its performance, and it can still maintain its superior performance in high temperature environment. According to the introduction of relevant data, XPS extruded insulation board can maintain excellent performance even if it is used for 30-40 years, and it does not It will decompose or mildew without volatilization of toxic substances.

 

 

 

Because the thermal conductivity of foaming agent used in polyurethane is much lower than that of air, the thermal insulation performance of rigid polyurethane foam is better than that of air only materials such as mineral wool, glass fiber and polystyrene.

 

 

 

The excellent closed cell structure and surface material of corrosion-resistant polyurethane rigid foam make it have more superior air and water resistance performance, and it can be made into inlaid connection structure when forming, which is easy for post assembly. It does not need extra insulating layer to prevent moisture, which saves the trouble of laying insulating layer. These properties can not be possessed by other insulating materials at the same time.

 

 

 

Compared with other insulating materials, polyurethane rigid foam has the best thermal insulation performance. Therefore, the thinner polyurethane sandwich panel can meet the relevant regulations on the limit of building energy consumption, so that the thinner panel can be used in the construction to save the building space; the quality is stable and the production efficiency is high.

 

 

 

In the case of rapid increase in demand, the industrialization production line of polyurethane sandwich panel not only facilitates the quality control, but also brings good economy and competitiveness.
