Introduction to the advantages of polyurethane hard foam insulation composite board

Polyurethane hard foam insulation composite panel is a material widely used in the field of building insulation, with many significant advantages. The following is a detailed introduction:

Excellent thermal insulation performance

Principle: The inside of the polyurethane hard bubble is a closed-cell structure. This structure can effectively prevent air flow and greatly reduce the heat conduction efficiency. It's like wearing a super warm 'down jacket' to the house, locking the indoor temperature firmly and reducing heat transfer.

Data support: Its thermal conductivity can be as low as 0.018 - 0.024W/(m·K), and the insulation effect is better than other common insulation materials such as polystyrene plates (thermal conductivity is about 0.03 - 0.041W/(m·K)).

High strength and strong resistance to deformation

Structural advantages: Polyurethane hard bubbles are closely combined with the surface layer materials of composite boards (such as color steel plates, aluminum plates, etc.) through a special bonding process to form a very strong structure. This structure allows the composite plate to disperse stress evenly when subjected to external forces, and is not prone to deformation or damage.

Practical application: In the building exterior wall insulation system, even if encountering natural disasters such as strong winds and earthquakes, the polyurethane hard bubble insulation composite panel can maintain the stability of the structure and ensure the long-term effectiveness of the insulation system.

Good waterproof and moisture-proof performance

Covercell structure characteristics: Since the closed cell rate of polyurethane hard bubbles is as high as more than 90%, it is difficult for moisture to penetrate into the inside of the material. This is like putting a waterproof 'raincoat' on the building, which can effectively prevent rainwater, moisture and other erosion of building walls and protect the building structure from damage.

Comparative advantages: Compared with some insulation materials with higher water absorption, polyurethane hard foam insulation composite panels will not cause problems such as degradation in insulation performance and increase weight due to water absorption, which extends the service life of the material.

Good dimensional stability

Less affected by the environment: The polyurethane hard bubble insulation composite panel has very little change in size under different temperature and humidity environments. This means that during long-term use, it will not cause cracking, falling off and other problems due to environmental changes, ensuring the integrity and stability of the insulation system.

Construction convenience: Stable size also brings convenience to construction. Construction personnel can install composite panels more accurately to reduce construction errors and rework caused by changes in material size.

Convenient construction and high efficiency

Modular design: Polyurethane hard bubble insulation composite panels are usually produced in modular form, with uniform size and specifications. They can be spliced and installed directly at the construction site without complicated on-site processing.

Shorten the construction period: Compared with the traditional insulation construction method, the use of polyurethane hard foam insulation composite panels can greatly shorten the construction cycle and reduce construction costs. For example, in some large-scale construction projects, the use of this composite panel can reduce the construction time of exterior wall insulation by 30% - 50%.

Good environmental performance

Environmentally friendly production process: Polyurethane hard foaming can be used to use environmentally friendly foaming agents during the production process to reduce damage to the ozone layer. At the same time, there is relatively little waste in its production process and has a small impact on the environment.

Recyclable: Some polyurethane hard foam insulation composite panels can be recycled and reused after reaching their service life, reducing the generation of construction waste and in line with the concept of sustainable development.
