Global specialty chemicals company Huntsman was invited to participate in the exhibition on August 3, 2023 -The "FBC China International Door, Window and Curtain Wall Expo" was held at the Shanghai National Convention and Exhibition Center on the 6th. In response to the national "dual carbon" policy, Huntsman has been intensively cultivating the low-carbon field of buildings for many years. This time, together with Shanghai Jiren New Material Technology Co., Ltd., it is the first time that Huntsman will jointly appear at the Flagship Expo for Professional Door, Window and Curtain Wall Systems in the Asia-Pacific Region (Booth No.: 8515, Hall 8.2) , to bring users a new generation of polyurethane environmental protection and energy-saving door and window solutions, display cutting-edge technologies and low-carbon materials, deeply explore the path of carbon reduction in application fields, analyze the innovation and upgrading of polyurethane doors and windows, and describe ultra-low energy consumption buildings to empower low-carbon living Beautiful blueprint with city.
"Double carbon" traction, green and energy-saving buildings are imperative
The data shows that the carbon emissions in the construction sector account for about 50% of the carbon emissions of the whole society, and the green and low-carbon transformation of buildings is of great significance for my country to realize the dual-carbon strategy. Under the guidance of the "1+N" top-level framework of the State Council's carbon peak carbon neutralization, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development and other departments have successively issued a number of guiding policies on circular economy and building energy conservation. Green, low-carbon, and energy-saving have become the development of the construction industry It has also become an important part of China's sustainable development.
Selecting high-performance thermal insulation and energy-saving materials and improving and optimizing the design of the exterior wall envelope are one of the effective solutions to improve building energy efficiency and reduce carbon emissions of the building itself. As one of the four major parts of the building's main energy consumption, the energy consumption of doors and windows should not be underestimated. According to incomplete statistics, as far as typical enclosure components in my country are concerned, the area of doors and windows accounts for less than 20% of the enclosure area, but their energy consumption can account for 40%-50% of building energy consumption. An important part of the carbon transition. In recent years, external windows, as a significant leakage point of building energy consumption, have received extensive attention from the industry, and various localities have successively raised the original energy-saving doors and windows standards. Shanghai’s ultra-low energy consumption standard stipulates that the K value of the entire window shall not exceed 1.4 W/m²·K; while Beijing’s implementation standard is more stringent, stipulating that the heat transfer coefficient of the entire window shall not exceed 1.1W/m²·K, which is comparable to the energy-saving properties of buildings in Germany and South Korea. The requirements of countries with high standards are basically the same.
Facing the rapidly increasing demand for carbon reduction in buildings, the pain points and challenges of the traditional door and window industry are becoming increasingly severe: the entire window has high carbon emissions, and the carbon dioxide emission per ton of aluminum profiles can reach 21.3 tons; heat conduction Poor coefficient ※, aluminum alloy doors and windows commonly used in the market have very high thermal conductivity, poor thermal insulation and heat insulation performance; low reliability, easy to be corroded by acid and alkali, and easy to condense in winter; high cost, aluminum doors and windows are expensive, Plastic-steel windows are cheap but vary in quality.
Combination between strong companies, polyurethane energy-saving doors and windows define the new direction of low-carbon buildings
Aiming at the market demand for energy-saving and low-carbon buildings, and to meet the challenges of the door and window industry, Huntsman, relying on its excellent performance, carbon-reducing and environmentally friendly polyurethane composite solutions, has joined forces with Jiren Technology to launch The result of innovative cooperation - a new generation of glass fiber reinforced polyurethane composite material energy-saving doors and windows, and in the form of scene-based display, it will bring users a new experience.
At present, the mainstream door and window profiles in the market are aluminum alloy and PVC. The glass fiber reinforced polyurethane profile brings the innovation of a new generation of door and window materials. Compared with domestic ordinary aluminum alloy and PVC plastic steel door and window profiles, it has the following obvious advantages:
Low-carbon and energy-saving: The thermal conductivity of this profile is 1/700 of that of ordinary aluminum alloy, and the thermal conductivity is only 0.35W/m·K※. In addition, its production energy consumption is only 1/60 of ordinary aluminum alloy. From the molecular structure, formula, production process, to the overall solution of materials, energy saving and low carbon are maintained.
Beautiful appearance: The section of this profile is small and beautiful, and it provides enough design freedom. Its surface is smooth and has good adhesion, which is beneficial to all kinds of surface Coating treatment provides customers with more color options.
Good reliability: glass fiber reinforced polyurethane composite material is light in weight and high in strength, and its tensile strength is 6~8 times that of ordinary aluminum alloy and 3~7 times that of steel ※, and acid and alkali resistance, salt spray resistance. Therefore, the profiled doors and windows have outstanding performance in thermal insulation, wind pressure resistance, sound insulation, corrosion resistance, fire prevention and other aspects. The TEROL® recycled polyester polyol contained in its profiles significantly improves fire performance.
Good economy: Under the condition of completely equal thermal performance, the overall window cost of polyurethane doors and windows is more controllable.
At present, Huntsman glass fiber reinforced polyurethane composite door and window profiles have been widely used in public buildings such as high-end residential buildings, culture, education and medical care, such as large-scale residential communities in Lingang New City and their supporting facilities, Shanghai Ninth People's Hospital, West Bund Artificial Intelligence Conference, Shanghai Lingang Talent Apartment, etc., have been highly recognized by users for their excellent energy-saving and environmental protection performance.
Lvyin Yongzhu, injecting strong momentum into sustainable development
Innovation comes from the transformation of materials; development comes from the support of technology. The impressive performance of glass fiber reinforced polyurethane composite doors and windows is largely due to its polyurethane matrix. As a practitioner and advocate of circular economy, Huntsman developed TEROL® recycled polyester polyol based on PET plastic recycling technology, which can be used as raw materials for various polyurethane products, and PET plastic is recycled in its components The content can reach 60%*, which reduces the carbon footprint of building materials in the production stage. As early as June 2021, Huntsman cooperated with the Shanghai Advanced Research Institute of the Chinese Academy of Sciences to carry out life cycle carbon footprint assessment based on polyurethane product production and downstream applications, which also includes carbon calculation of polyurethane composite door and window profiles.
This year, Huntsman launched the "Luyin Yongzhu" low-carbon and energy-saving new material solution platform - bringing together Huntsman insulation sandwich panels, energy-saving system doors and windows, spray insulation foam and other polyurethane low-carbon The comprehensive innovation platform of construction products aims to explore the application of polyurethane cutting-edge technology in multiple fields and scenarios in the construction industry by creating a product matrix and technological value, and provide technical momentum for energy conservation and carbon reduction for the sustainable operation of ultra-low energy buildings. The polyurethane environmental protection and energy-saving door and window solution is also an important innovation achievement of the "Lvyin Yongzhu" low-carbon energy-saving new material solution platform.
Closely around the "dual carbon" system project, Huntsman has always been committed to the research and development of innovative and more advanced green and energy-saving technologies, with circular economy as the engine and ultra-low energy consumption buildings as the starting point, joining hands with upstream and downstream Industrial chain partners, through circular technology empowerment and industrial chain value linkage, jointly promote the green and low-carbon upgrade of China's construction industry, and help social development move towards a lower-carbon, more resilient, and more sustainable future.
