Polyurethane rigid foam insulation composite board is a new type of building insulation material that uses polyurethane rigid foam as the core material and is compounded with non-decorative surface layers such as cement fiber boards and metal boards. It has the following performance characteristics:
1. Thermal insulation performance
Low thermal conductivity: The thermal conductivity of polyurethane rigid foam is as low as 0.018-0.024W/(m·K), which is about half that of EPS (polystyrene foam). It is one of the lowest thermal conductivity coefficients among all current insulation materials. This characteristic makes polyurethane rigid foam insulation composite panels excellent in thermal insulation and can effectively reduce the energy consumption of buildings.
High closed cell rate: The closed cell rate of polyurethane rigid foam is more than 90%. It is a hydrophobic material and will not increase the thermal conductivity due to moisture absorption, thus ensuring its long-term stable thermal insulation performance.
2. Fire performance
High fire protection level: Polyurethane rigid foam insulation composite panels usually meet B1 level fire protection standards and have good fire protection performance. After adding flame retardants, polyurethane becomes a flame-retardant self-extinguishing material with a softening point that can reach over 250 degrees Celsius and will only decompose at higher temperatures.
Flame retardant and self-extinguishing: When polyurethane burns, it will form carbon deposits on the surface of the foam. This layer of carbon deposits helps to isolate the foam below, thus effectively preventing the spread of flames. In addition, polyurethane does not produce harmful gases at high temperatures.
3. Mechanical properties
High compressive strength: When the density of the core material is in the range of 35-40kg/m³, the compressive strength of the polyurethane rigid foam insulation composite board is ≥200kPa, which can meet the load-bearing requirements of the building.
Strong resistance to deformation: The material is not easy to crack, the finish is stable and safe, and it can maintain long-term flatness and beauty.
4. Weather resistance and stability
Good weather resistance: The polyurethane rigid foam insulation composite board has undergone weather resistance testing for more than 6 months. Its performance is stable and can last as long as the building. It has good chemical stability, excellent corrosion resistance, and can be used for a long time in various harsh environments.
Stable structure: The porosity structure of rigid polyurethane foam is stable and is basically a closed-cell structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption.
5. Light weight, high strength and convenient construction
Lightweight and high strength: Polyurethane rigid foam insulation composite panels are light in weight and easy to transport and install. At the same time, its high strength properties allow it to be used both as a load-bearing structure and as an envelope structure.
Convenient construction: This material is produced in a factory with high dimensional accuracy and is easy and quick to install. Its plate design covers various forms such as cap type and hidden type. It is combined with optimizations such as stacking technology and three-wave crest structure to improve sealing and pressure resistance and adapt to the needs of different architectural scenes.
6. Environmental protection and energy saving
Environmentally friendly materials: The polyurethane rigid foam insulation composite board uses a fluorine-free foaming process and does not use harmful substances banned or restricted by the state. It is green and environmentally friendly.
Significant energy-saving effect: Due to its excellent thermal insulation performance, this material can reduce the thickness of the building's outer envelope and increase the indoor use area while meeting the same insulation requirements. At the same time, it can also effectively reduce the energy consumption of buildings and comply with national energy conservation and emission reduction policy requirements.
