Introduction
As the acceleration of global industrialization, the emissions of volatile organic compounds (VOCs) are attracting increasing attention. VOCs not only cause serious pollution to the environment, but also pose a potential threat to human health. As a widely used polymer material, polyurethane materials occupy an important position in many industries such as construction, automobiles, and furniture. However, the catalysts used in the traditional polyurethane production process often lead to higher VOC emissions, which not only increases the environmental protection costs of the enterprise, but also has an unnegligible impact on the environment. Therefore, the development of highly efficient and low VOC emission polyurethane catalysts has become the key to solving this problem.
NIAX polyurethane catalyst, as a new generation of environmentally friendly catalysts, has the advantage of significantly reducing VOC emissions. The catalyst was developed by Huntsman Corporation in the United States. After years of laboratory research and industrial application verification, it has been widely used in major polyurethane manufacturers around the world. Compared with traditional catalysts, NIAX catalysts significantly reduce the release of harmful gases while improving reaction efficiency, providing strong support for achieving green production and sustainable development.
This article will discuss in detail the basic principles, product parameters, application scenarios, domestic and foreign research results of NIAX polyurethane catalysts, aiming to fully demonstrate its importance in reducing industrial VOC emissions, and provide relevant enterprises and research The organization provides reference.
The working principle of NIAX polyurethane catalyst
The main components of the NIAX polyurethane catalyst are based on a composite system of metal organic compounds and amine compounds. These components play a role in promoting the reaction of isocyanate with polyols during the polyurethane synthesis process. Specifically, NIAX catalysts accelerate reactions and reduce VOC emissions through the following mechanisms:
-
Formation of active centers: The metal organic compounds in NIAX catalysts can form efficient active centers in the reaction system, thereby significantly increasing the reaction rate. These active centers can effectively reduce the activation energy of the reaction, making the reaction between isocyanate and polyol more rapid and thorough. Compared with traditional tertiary amine catalysts, the active center of NIAX catalysts is more stable and can maintain efficient catalytic performance over a wide temperature range, avoiding incomplete reactions or by-product generation caused by temperature fluctuations.
-
Selective Catalysis: NIAX catalyst has good selectivity and can preferentially promote the occurrence of main reactions and inhibit the progress of side reactions. During the polyurethane synthesis process, in addition to the target products, some by-products will also be produced, such as carbon dioxide, methane and other VOCs. NIAX catalysts reduce the generation of these byproducts by optimizing the reaction pathway, thereby reducing VOC emissions. Studies have shown that when using NIAX catalyst, VOC emissions can be reduced by 30%-50%, and the specific value depends on the reaction conditions and the choice of raw materials.
-
Synergy Effect: There is a synergistic effect between the amine compounds and metal organic compounds in the NIAX catalyst, further enhancing the overall performance of the catalyst. Amines can weakly interact with isocyanate to form intermediates, thereby promoting subsequent polymerization. Meanwhile, metal organic compounds are responsible for activating the hydroxyl groups in the polyol, making it easier to react with isocyanate. This synergistic effect not only improves the reaction efficiency, but also reduces the amount of catalyst used and reduces production costs.
-
Environmental Friendliness: The design of NIAX catalyst fully takes into account environmental protection requirements and uses non-toxic and harmless raw materials to avoid the use of heavy metal ions and harmful solvents common in traditional catalysts. In addition, NIAX catalyst has good thermal stability and chemical stability, and can be used for a long time under high temperature and high pressure conditions without deactivation, reducing the frequency of catalyst replacement and reducing the difficulty of handling waste catalysts.
To sum up, NIAX polyurethane catalyst achieves effective control of VOC emissions during polyurethane synthesis by forming efficient and stable active centers, selectively catalyzing main reactions, exerting synergistic effects, and using environmentally friendly raw materials. Next, we will introduce the product parameters of NIAX catalyst in detail and their performance in different application scenarios.

Next, we will further explore the specific performance of NIAX catalysts in different application scenarios.
Application scenarios of NIAX polyurethane catalyst
NIAX polyurethane catalyst has been widely used in many industries due to its unique catalytic performance and environmental protection advantages. The following are several typical application scenarios that demonstrate the significant effects of NIAX catalysts in reducing VOC emissions.

In the furniture manufacturing process, polyurethane foam materials are often used for filling and buffering layers of sofas, mattresses and other products. Traditional catalysts will produce a large amount of VOC during foaming, such as A and DAC, which not only affects the health of workers, but may also lead to a decline in product quality. After using NIAX catalyst, VOC emissions are significantly reduced, while the density and hardness of the foam are more uniform, improving the overall performance of the product.

Polyurethane foam and coating are widely used in automotive interior materials such as seats, instrument panels, door panels. The VOC generated by these materials during the production process not only causes pollution to the workshop environment, but may also affect the air quality in the car, thus endangering the health of the driver and passengers. The application of NIAX catalysts effectively solves this problem, significantly reducing VOC emissions, improving the workshop working environment and in-vehicle air quality.
According to a study on automotive interior materials, VOC emissions from production lines using NIAX catalysts were reduced by 35%, and the physical properties of the products (such as tear resistance and wear resistance) were significantly improved.
