In the news released on January 10th, 2025, it was mentioned that according to Deng Gang, vice president of the China Insulation and Energy-saving Materials Association, high-performance modified phenolic board (SQPF board) as an insulation material has been recognized by the industry for its high insulation and fire resistance. Many countries, including South Korea, Japan, Saudi Arabia, Brazil, and Australia, have promoted using modified phenolic boards as the main insulation material. Among them, more than 95% of new buildings in South Korea and Japan have a usage rate of more than 50%. Australia has also gradually transformed its insulation materials into modified phenolic boards under the promotion of Kingspan in the UK. The Middle East, Europe, and the United States have also been constantly coming to Shengquan to consult on modified phenolic board and phenolic resin cooperation matters.
The application prospects of phenolic foam board in the field of building energy conservation are relatively broad. The following is a specific analysis:
Advantages
Excellent thermal insulation performance: The thermal conductivity of phenolic foam board is low, generally lower than 0.030W/(m・K), which is much lower than traditional building insulation materials such as rock wool and glass wool, and can effectively reduce heat transfer. , reducing the heat loss of the building in winter and the heat absorption in summer, thereby significantly reducing the energy consumption of the building, which can reduce the energy consumption of the building by more than 30%.
Excellent fireproof performance: Phenolic foam board does not burn, smoke, toxicity, or drip when exposed to open flames. Its combustion performance is up to Class A. It has carbonization, no dripping, no curling, and no melting under the direct action of flames. Phenomenon, can effectively prevent the spread of fire when a fire occurs, buy time for personnel evacuation and fire rescue, which is crucial to improving the safety of buildings. In places with strict fire protection requirements, such as steel structure factories, large industrial factories, activities The advantages of clean rooms, cold storage and clean workshops are obvious.
Good environmental characteristics: Freon is not used as a foaming agent in the production process, which meets international environmental standards. Its molecular structure contains hydrogen, oxygen, and carbon elements. When decomposed at high temperature, the gas released is non-toxic and odorless, and is harmless to the human body. It is harmless to the environment and will not release any harmful substances during use, which meets the national green environmental protection requirements.
Lightweight and easy to construct: The density of phenolic insulation board is below 100kg/m³, and can reach about 50kg/m³. It is light in weight, which can reduce the weight of the building and the load of the building. At the same time, its construction is simple and fast, which can improve work efficiency. , which can reduce construction costs and difficulty.
Market demand
Policy promotion: The requirements for building energy conservation and environmental protection are constantly increasing worldwide. Governments of various countries have introduced a series of policies and regulations to promote the development of green buildings and energy-saving materials. Phenolic foam board, as a high-efficiency energy-saving material, has been encouraged by policies. And support, such as the continuous improvement of China's building energy-saving standards, provides a broad market space for the application of phenolic foam boards.
Demand for new buildings: With the rapid development of the global economy, the urbanization process is accelerating, the number of new buildings is increasing year by year, and the demand for high-performance insulation materials is also increasing. Phenolic foam boards are widely used in high-rise buildings, It has been widely used in the thermal insulation system of new buildings such as residential buildings and industrial plants. In some developed countries, such as South Korea, more than 95% of new buildings and Japan, the usage rate exceeds 50%. The application of foam boards in new construction around the world provides a good demonstration.
Energy-saving renovation of existing buildings: In the energy-saving renovation of existing buildings, phenolic foam boards also have great application potential. For those existing buildings with poor thermal insulation performance and high energy consumption, phenolic foam boards can be used for external wall insulation, Renovations such as roof insulation can effectively improve the building's energy-saving level, reduce energy consumption, and improve the indoor thermal environment.
Technology Development
Performance improvement: By developing new phenolic foam board materials, improving production processes and formulas, such as adding fiber reinforcement materials and optimizing the pore structure, the compressive strength, toughness and weather resistance of phenolic foam boards can be further improved, making them more durable. It can better meet the long-term use requirements of the external insulation system of the building's exterior wall, and at the same time expand its application in more building parts and under different climatic conditions.
Multifunctional composite: Compounding phenolic foam with other materials, such as inorganic fibers, silicates, etc., can produce composite insulation boards with multiple functions, such as heat insulation, fire resistance, waterproofing, sound insulation, etc. High-performance composite panels can meet the diverse needs of different buildings and application fields, and further improve their competitiveness in the field of building energy conservation.
Cost and Benefit
Although the current production cost of phenolic foam boards is relatively high, which limits their application in some low-cost construction projects, their production costs are expected to gradually decrease with the continuous advancement of technology and the expansion of production scale. In the long run, the comprehensive benefits of using phenolic foam boards, such as energy saving and reduced maintenance costs, are significant. For example, it can reduce the energy cost expenditure of the building during use and reduce the maintenance costs caused by the decline in the performance of insulation materials. and replacement costs, etc., with good economic and social benefits.
