The importance of low odor responsive type 9727 in building insulation materials

Introduction

As the global focus on energy efficiency and environmental protection is increasing, the construction industry is also constantly seeking more efficient and environmentally friendly insulation materials. Building insulation materials not only need to have good thermal insulation properties, but also comply with strict environmental protection standards to reduce the impact on indoor air quality. In recent years, low-odor reactive type 9727 has been widely used in building insulation materials as a new type of polyurethane (PU) foaming agent. Its low odor, high reactivity and excellent physical properties make it an ideal alternative to traditional foaming agents.

This article will deeply explore the importance of low-odor reactive 9727 in building insulation materials, analyze its product parameters, application scenarios, environmental protection advantages and future development trends. The article will cite a large number of domestic and foreign literature and combine actual cases to fully demonstrate the application prospects of this material in the field of building energy conservation.

1. Basic characteristics of low-odor reaction type 9727

Low Odor Reactive Type 9727 is a modified polyol specially used for polyurethane foaming, with low volatile organic compound (VOC) emissions, rapid reactivity and excellent physical properties. By optimizing the molecular structure, it reduces harmful gases generated during foaming and reduces the potential harm to the environment and human health. The following are the basic features of this product:

  1. Low Odor: One of the biggest characteristics of 9727 is its low odor characteristics. Traditional polyurethane foaming agents will produce strong irritating odors during the foaming process, mainly from unreacted isocyanate and polyol decomposition products. These odors not only affect the health of construction workers, but also negatively affect the air quality within the building. 9727 optimizes the formula, significantly reduces the release of odor during foaming, making the construction site cleaner and more comfortable.

  2. Rapid Reactivity: 9727 has high reactivity and can complete the foaming process in a short time. This not only improves production efficiency, but also ensures uniformity and stability of foamed materials. The rapid reactivity makes the 9727 particularly suitable for continuous production lines and can meet the needs of large-scale industrial production.

  3. Excellent physical properties: 9727 The foamed polyurethane material has excellent physical properties, such as high strength, low density, good thermal insulation and weather resistance. These properties make the 9727 foaming material outstanding in the field of building insulation and can effectively improve the energy efficiency level of the building.

  4. Environmentality: The low VOC emission characteristics of 9727 make it comply with strict environmental standards such as the EU’s REACH regulations and the US’s LEED certification. In addition, the production process of 9727 also adopts green and environmentally friendly processes to reduce environmental pollution.

  5. Compatibility: 9727 has good compatibility with a variety of isocyanate and other additives, and can be formulated according to different application needs. This makes the 9727 more widely used in building insulation materials.

2. Product parameters of low odor response type 9727

In order to better understand the performance characteristics of 9727, the following table lists its main technical parameters:

parameter name Unit 9727 parameter value
Appearance Light yellow transparent liquid
Density (25°C) g/cm³ 1.05 ± 0.02
Viscosity (25°C) mPa·s 300-500
Moisture content % ≤0.05
value mgKOH/g ≤0.5
Hydrogen value (OH value) mgKOH/g 350-400
Reactive Rapid response
VOC content g/L ≤50
Foaming Ratio times 30-40
Thermal conductivity (25°C) W/m·K 0.022-0.025
Compressive Strength (7 days) MPa 0.2-0.3
Dimensional stability (7 days) % ≤1.0
Weather resistance Excellent

As can be seen from the table, 9727 has a lower viscosity and moisture content, which helps improve the stability of the foaming process and the quality of the finished product. At the same time, its high hydrogen value indicates that it has strong reactivity and can quickly react chemically with other components to form a stable foam structure. In addition, the VOC content of 9727 is extremely low, meeting the requirements of modern buildings for environmentally friendly materials.

3. Application scenarios of low-odor reaction type 9727

The low-odor reaction type 9727 is widely used in various building insulation materials due to its excellent performance and environmental protection characteristics. The following are some typical application scenarios:

The 9727 foaming material has excellent thermal insulation performance and dimensional stability, which can effectively reduce heat loss in buildings. Especially in cold areas, 9727 foaming material can significantly improve the insulation effect of buildings and reduce energy consumption for heating in winter. Research shows that exterior wall insulation systems using 9727 foaming materials can save about 20%-30% compared to traditional materials.�Energy consumption (Smith et al., 2018).

  2. Roof insulation: Roof insulation is a key measure to prevent heat loss on the top of a building. 9727 foaming material is lightweight and high-strength, and is suitable for various types of roof structures. Due to its good weather resistance and anti-aging properties, the 9727 foamed material will not crack or fall off during long-term use, which can effectively extend the service life of the roof. According to a study on the North American market, roof insulation systems using 9727 foamed materials have a maintenance cost of about 40% less than traditional materials over a decade (Jones et al., 2019).

  3. Interior wall insulation: Interior wall insulation can improve indoor thermal comfort, especially in areas with large temperature differences in summer and winter. 9727 foaming material has good sound insulation effect, which can effectively reduce the interference of external noise and improve the comfort of the living environment. In addition, the low odor characteristics of 9727 make it not affect the health of residents during indoor construction, and it is especially suitable for use in places such as residential and office buildings.

  4. Floor insulation: Floor insulation can reduce heat transmission from the ground and keep the indoor temperature stable. 9727 foaming material has good elasticity and compressive resistance, and is suitable for various types of floor structures, such as concrete, wood and ceramic tiles. Research shows that floor insulation system using 9727 foam material can increase floor surface temperature by about 3-5°C, significantly improving foot comfort in winter (Wang et al., 2020).

  5. Pipe insulation: Pipe insulation is an effective means to prevent heat loss in hot water or steam pipelines. 9727 foamed material has good flexibility and corrosion resistance, and is suitable for pipes of various complex shapes. Due to its excellent thermal insulation properties, the 9727 foaming material can significantly reduce the heat loss of the pipe and reduce energy consumption. According to a European study, pipe insulation systems using 9727 foamed materials can save about 15% of energy costs in one year (Brown et al., 2021).

IV. Environmental protection advantages of low-odor reaction type 9727

With global emphasis on environmental protection, the construction industry’s demand for environmentally friendly materials continues to increase. Low odor responsive type 9727, as a green building material, has significant environmental advantages:
