Hard foam materials, i.e., rigid polyurethane foams, are widely used in daily life due to their light weight, high strength, good thermal insulation and excellent mechanical properties. Here are some specific application areas:
1. Building energy efficiency: Hard foams have excellent thermal insulation properties, suitable for roofs, walls, ceilings, floors, etc. of buildings, as thermal insulation materials, helping to improve the energy efficiency of buildings.
2. Refrigeration and insulation: In refrigeration equipment such as refrigerators, freezers, cold storages and refrigerated trucks, rigid foam materials are used as thermal insulation materials to effectively maintain low temperatures and reduce energy consumption.
3. Industrial equipment insulation: The pipelines and storage tanks in chemical, petroleum, natural gas and other industries use hard foam materials for heat preservation to reduce heat loss.
4. Transportation: Automotive roofs, interior trims, etc. use hard foam materials to provide light weight and good cushioning properties of materials.
5. Furniture manufacturing: Rigid foam materials are used in the production of sofas, mattresses and other furniture products because of their structural stability and comfort.
6. Imitation wood application: High density rigid foams or glass fiber reinforced rigid foams can be used as structural materials to mimic the use of natural wood for high-grade products.
7. Packaging materials: The cushioning properties of rigid foams make them an ideal packaging material for protecting fragile articles.
8. Sports equipment: Hard foam materials are used to make sports protectors, helmets, etc. because of their good elasticity and impact absorption properties.
9. Electronic equipment: Used in the packaging and components of electronic products such as mobile phones and computers to provide shockproof and protection.
10. Shoe material: Hard foam materials are used in insoles and soles to provide comfort and support.
With the development of technology and the increase of market demand, the application fields of rigid foam materials are still expanding, such as the use of insulation materials for LNG ships, and the potential application in aerospace field. In addition, polyurethane rigid foam is regarded as an important development direction in the field of building energy conservation in the future because of its environmental characteristics and excellent performance.
