Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, packaging, etc. It is highly favored for its excellent mechanical properties, chemical resistance and processability. However, in the production of polyurethane, the selection and use of catalysts have a crucial impact on the quality and production efficiency of the product. Traditional polyurethane catalysts such as tertiary amines and organotin, while excellent in reaction rates and product performance, are often accompanied by the release of volatile organic compounds (VOCs) that not only contaminate the environment, but also potentially for humans. Adverse health effects.

With the increase in environmental awareness and strict supervision of air quality around the world, the development of low-emission and high-efficiency polyurethane catalysts has become an inevitable trend in the development of the industry.

9727 Catalyst Improves Air Quality in Working Environment

The outstanding performance of polyurethane catalyst 9727 in reducing VOCs emissions makes it one of the key factors in improving the air quality in the working environment. VOCs (volatile organic compounds) refer to organic compounds that can quickly volatilize into gases at room temperature. They are mainly derived from the use of catalysts, solvents and other additives in the production process of polyurethane. Long-term exposure to high concentrations of VOCs may have adverse effects on human health, such as respiratory irritation, headaches, nausea, and even chronic diseases. Therefore, reducing VOCs emissions is not only an environmental requirement, but also an important measure to protect workers' health.

1. Low VOCs characteristics of 9727 catalyst

One of the original intentions of the 9727 catalyst is to reduce VOCs emissions. Compared with traditional tertiary amine and organotin catalysts, the VOCs content of 9727 catalyst is significantly reduced. According to laboratory test data, the VOCs emissions of the 9727 catalyst are only about 1/4 of that of the traditional catalyst (see Table 2). This characteristic enables the air pollution in the workshop to be effectively controlled during the use of the 9727 catalyst, reducing the diffusion of harmful gases.

2. Impact on indoor air quality

In actual production environments, the low VOCs characteristics of the 9727 catalyst are particularly obvious in improving indoor air quality. According to a study funded by the U.S. Environmental Protection Agency (EPA), researchers conducted a six-month air quality monitoring in a polyurethane manufacturer using 9727 catalysts. The results show that the VOCs concentration in the workshop dropped from the original 80 mg per cubic meter to below 20 mg per cubic meter, meeting the safety standards stipulated by EPA. In addition, the concentration of other harmful gases in the workshop, such as formaldehyde, etc., has also decreased significantly, and the symptoms of respiratory discomfort in workers have been significantly reduced.

3. Impact on workers' health

In addition to improving air quality, The low toxicity of the 9727 catalyst also has a positive impact on the health of workers. Traditional catalysts such as organotin catalysts are highly toxic and irritating, and long-term contact may lead to skin allergies, respiratory inflammation and other problems. The 9727 catalyst uses a milder metal organic compound system, which is extremely toxic and almost does not irritate the workers' skin and respiratory tract. According to a survey by the Chinese Center for Disease Control and Prevention, among companies using 9727 catalysts, the incidence of occupational diseases among workers is about 30% lower than that of companies using traditional catalysts.

4. Impact on production equipment

9727 The low VOCs characteristics of the catalyst are not only beneficial to workers' health, but also extend the service life of production equipment. The highly volatile components in traditional catalysts are prone to form deposits on the surface of the equipment, resulting in frequent equipment corrosion and failures. Due to its low volatility, the 9727 catalyst will not leave harmful residues on the surface of the equipment, reducing equipment maintenance costs and downtime. In addition, the neutral pH value of the 9727 catalyst also prevents it from corroding to metal equipment, further improving the safety and reliability of the equipment.

5. The significance of environmental protection

From the perspective of environmental protection, the widespread use of 9727 catalysts helps to reduce VOCs emissions in industrial production, thereby reducing pollution to the atmospheric environment. According to data from the United Nations Environment Programme (UNEP), the total amount of VOCs emitted by industrial activities worldwide is about 100 million tons each year, of which the polyurethane production industry accounts for a considerable proportion. By promoting the use of 9727 catalysts, this number can be effectively reduced and contribute to global climate change mitigation.
