The role of low-odor responsive 9727 in automotive interior manufacturing
Introduction
With the rapid development of the global automobile industry, consumers have higher and higher requirements for automobile quality. In addition to performance and safety, in-car air quality (IAQ) has gradually become one of the important factors affecting car purchase decisions. Studies have shown that volatile organic compounds (VOCs) and odors in the car are the main reasons for poor air quality in the car, and these substances are mainly derived from car interior materials. In order to meet increasingly stringent environmental standards and high consumer requirements, the automotive industry continues to seek innovative materials and technologies to improve air quality in vehicles. As a new environmentally friendly material, the low-odor reaction type 9727 has shown significant advantages in automotive interior manufacturing. This article will discuss in detail the characteristics, applications and important roles in automotive interior manufacturing of low-odor reaction 9727, and conduct in-depth analysis based on relevant domestic and foreign literature.

As can be seen from the table, the low-odor reactive type 9727 has a high solids content and a low VOC content, which makes it almost impossible to produce odor during use, which is in line with the environmentally friendly materials of Hyundai’s interior. Strict requirements. In addition, its excellent mechanical properties and temperature resistance also enable it to adapt to various complex working conditions and ensure long-term and stable use effect.
2. Application fields of low-odor reaction type 9727
The low-odor responsive 9727 is widely used in various parts of automotive interiors, especially when high-strength bonding and low VOC emissions are required. Specific applications include but are not limited to the following aspects:
2.1 Seat System
Seaters are one of the important components of the car interior and directly affect the comfort and safety of the driver and passengers. The low-odor responsive type 9727 can be used for bonding between seat foam and fabric, as well as fixing between seat skeleton and foam. Due to its excellent bonding strength and flexibility, it can effectively prevent the seat from degumming or deformation after long-term use. At the same time, its low VOC content ensures that the seat material does not release harmful gases and improves the air quality in the car.
2.2 Dashboard
As the core component of the cockpit, the instrument panel not only performs the function of displaying vehicle information, but also plays a role in decoration and protection. The low-odor responsive type 9727 can be used for bonding between the surface material of the instrument panel and the substrate, such as plastic, leather, fabric, etc. Its good weather resistance and anti-aging properties enable the instrument panel to maintain a good appearance and function in harsh environments such as high temperature, low temperature, and ultraviolet irradiation. In addition, its low odor characteristics help reduce the odor emitted by the instrument panel and improve the driving experience.
2.3 Door panels and handrails
Door panels and handrails are often contacted by drivers and passengers, so the choice of their materials is particularly critical. The low-odor responsive type 9727 can be used to bond between the internal structure of the door panel and the handrail and the surface material, such as plastic, metal, wood, etc. Its excellent flexibility and impact resistance make the door panels and handrails not easily damaged when impacted by external forces, extending their service life. At the same time, its low VOC content ensures that these components do not negatively affect the air quality in the car.
2.4 Carpet and ceiling
Carpet and ceiling are areas in the interior of the car that are prone to dust and odor accumulation. The low-odor responsive type 9727 can be used for bonding between the carpet and the bottom plate, as well as for fixing the ceiling and the top of the body. Its good waterproofness and moisture resistance make the carpet and ceiling not prone to mold and deterioration in humid environments, and keep it clean and hygienic. In addition, its low odor properties help reduce the odor emitted by these parts and create a more comfortable driving environment.
3. Technical advantages of low-odor reaction type 9727
Compared with traditional polyurethane adhesives, the low-odor reactive type 9727 shows significant technical advantages in many aspects, as follows:
3.1 Low VOC emissions
Traditional polyurethane adhesives release a large amount of volatile organic compounds (VOCs) during the curing process, which not only cause harm to human health, but also lead to a decrease in air quality in the car. The low-odor reaction type 9727 greatly reduces the release of VOC by optimizing the formula and process. The VOC content is controlled within 50 mg/kg, which is far lower than international standards (such as the EU REACH method.�). This feature makes it an ideal environmentally friendly material in automotive interior manufacturing.
3.2 High-strength bonding
The low odor reactive type 9727 has excellent adhesive properties and can form a firm adhesive layer on a variety of substrates. According to the test data, its initial strength can reach more than 1.5 MPa and final strength can reach more than 6.0 MPa, far exceeding the level of traditional adhesives. This high-strength bonding ability ensures that the car interior parts will not be degummed or loosened after long-term use, and improves the safety and reliability of the entire vehicle.
3.3 Excellent weather resistance
Automobile interior materials need to have good weather resistance to cope with various complex environmental conditions. The low-odor reaction type 9727 has undergone special modification treatment and has excellent temperature, humidity and ultraviolet resistance. Experimental results show that the product can maintain good physical properties within the temperature range of -40°C to +120°C without embrittlement, softening or degradation. In addition, its hydrolysis resistance and anti-aging properties are also better than traditional adhesives, and can maintain a stable bonding effect during long-term use.
3.4 Flexibility and impact resistance
Automobile interior parts may be impacted by external forces or bend and deformed during use, so higher requirements are placed on the flexibility and impact resistance of the material. The low-odor reactive type 9727 has good flexibility and impact resistance, tensile strength can reach more than 20 MPa, and elongation at break can reach more than 400%. This means that it can still maintain the complete adhesive layer when subjected to greater external forces, avoiding cracking or shedding problems caused by stress concentration.
3.5 Rapid curing
In the process of automotive interior manufacturing, production efficiency is an important consideration. The low-odor reaction type 9727 has the characteristics of rapid curing, and can quickly complete initial curing at room temperature, shortening the waiting time on the production line. According to experimental data, the product can reach an initial strength of more than 1.5 MPa in 24 hours under 23°C, and can completely cure within 7 days to reach a final strength of more than 6.0 MPa. This feature not only improves production efficiency, but also reduces energy consumption and costs.
