Chemical composition and molecular structure<\/strong><\/h4>\n8154 catalyst main component is Dibutyltin Dilaurate (DBTDL), a common organotin compound with high thermal and chemical stability. The molecular structure of DBTDL is shown in the figure:<\/p>\n [ text{Sn(OOCR)\u2082} ]<\/p>\n Where, R represents laurel group (C\u2081\u2081H\u2082\u2083COO\u207b). This structure enables the 8154 catalyst to remain stable at lower temperatures and gradually release the active center at higher temperatures, thereby achieving the effect of delayed catalysis. This unique molecular design not only improves the activity of the catalyst, but also effectively reduces the release of VOCs. <\/p>\n 2. Density and Viscosity<\/strong><\/h4>\n8154 catalyst has a density of 0.98-1.02 g\/cm\u00b3 and a viscosity of 50-100 mPa\u00b7s (measured at 25\u00b0C). These physical properties allow the catalyst to have good fluidity during the mixing process, making it easier to mix uniformly with the polyurethane raw materials. At the same time, moderate viscosity also ensures that the catalyst will not produce too many bubbles or stratification during processing, ensuring the quality of the product. <\/p>\n 3. Activation temperature and time<\/strong><\/h4>\n8154 catalyst activation temperature range is 60-80\u00b0C, and the activation time is 5-15 minutes. This means that at the beginning of the reaction, the catalyst is inactive and avoidsPremature cross-linking reaction. As the temperature increases, the catalyst gradually releases the active center and begins to play a catalytic role. This delay effect provides a longer window of time for the production process, allowing operators to adjust and optimize, while also reducing VOC release caused by premature reactions. <\/p>\n 4. Thermal Stability<\/strong><\/h4>\n8154 catalyst has excellent thermal stability and can maintain catalytic activity in high temperature environments above 200\u00b0C. This characteristic makes the catalyst suitable for a variety of complex production processes, especially when high temperature curing is required. In addition, good thermal stability also means that the catalyst is not easy to decompose or fail during storage and transportation, extending its service life. <\/p>\n 5. Volatile organic compounds content<\/strong><\/h4>\nAccording to laboratory tests, the VOC content of 8154 catalyst is less than 0.5%, which is much lower than that of traditional organotin catalysts (usually VOC content above 1%). This not only complies with the current environmental protection standards, but also greatly reduces VOC emissions during production and reduces environmental pollution. Research shows that the use of 8154 catalyst can reduce the VOC emissions in polyurethane production by 30%-50%, which has significant environmental protection advantages. <\/p>\n 6. Compatibility<\/strong><\/h4>\n8154 catalyst has good compatibility with a variety of polyurethane systems and is suitable for the production of soft, hard and semi-rigid polyurethane foams. Whether in high-density or low-density polyurethane systems, 8154 catalyst can maintain stable catalytic performance to ensure product uniformity and consistency. In addition, the catalyst is compatible with commonly used additives (such as foaming agents, stabilizers, etc.) and will not affect the effect of other additives. <\/p>\n 7. Scope of application<\/strong><\/h4>\n8154 catalysts are widely used in the production of various polyurethane products, including but not limited to the following fields:<\/p>\n \n- Building Insulation Materials<\/strong>: Used to produce highly efficient thermal insulation polyurethane foam boards with excellent insulation properties and low VOC emissions. <\/li>\n
- Furniture Manufacturing<\/strong>: Used to produce comfortable soft polyurethane foam pads for improved sitting feeling and durability. <\/li>\n
- Auto Industry<\/strong>: Used to produce lightweight, high-strength polyurethane components, such as seats, instrument panels, etc. <\/li>\n
- Packaging Material<\/strong>: Used to produce polyurethane foam packaging with excellent cushioning performance to protect fragile items. <\/li>\n<\/ul>\n
8. Shelf life<\/strong><\/h4>\n8154 The shelf life of the catalyst is 12 months, and the storage conditions are sealed, protected from light and dry. Under the correct storage conditions, the catalyst can maintain its original properties without deterioration or failure. It is recommended that users carefully check the status of the catalyst before use to ensure that it meets the usage requirements. <\/p>\n 8154 Catalyst Working Principle<\/h3>\nThe 8154 catalyst can perform well in reducing VOC emissions mainly due to its unique delayed catalytic mechanism. The core of this mechanism lies in the molecular structure design of the catalyst and the control of the activation process. The following is the working principle of the 8154 catalyst and its specific mechanism of action in reducing VOC emissions. <\/p>\n 1. Molecular mechanism of delayed catalysis<\/strong><\/h4>\n8154 The main component of the catalyst is dilaury dibutyltin (DBTDL), which contains two laurel groups and one tin atom in its molecular structure. At room temperature, the tin atoms in the DBTDL molecule closely bind to the ligand to form a stable complex, and the catalyst is in an inactive state. As the temperature increases, especially when the temperature reaches 60-80\u00b0C, the bond energy between the tin atom and the ligand gradually weakens, causing the ligand to gradually detach and expose the active center. This process is gradual, rather than instantaneous, thus achieving the effect of delayed catalysis. <\/p>\n Specifically, the delayed catalytic mechanism of 8154 catalyst can be divided into the following stages:<\/p>\n \n- \n
Initial Stage (<60\u00b0C)<\/strong>: The catalyst is in an inactive state, and the tin atoms are closely bound to the ligand and cannot participate in the catalytic reaction. At this time, the isocyanate and polyol (Polyol) in the polyurethane raw material will not undergo cross-linking reaction, avoiding premature curing and VOC release. <\/p>\n<\/li>\n- \n
Activation stage (60-80\u00b0C)<\/strong>: As the temperature increases, the bond energy between the tin atoms and the ligand gradually weakens, and some ligands begin to detach, exposing the active center . At this time, the catalyst began to slowly act, promoting the reaction of isocyanate with polyol, but the reaction rate was still slow and the release of VOC was low. <\/p>\n<\/li>\n- \n
Full activation phase (>80\u00b0C)<\/strong>: When the temperature exceeds 80\u00b0C, the catalyst is fully activated, the tin atoms are separated from all ligands, and all active centers are exposed. At this time, the catalytic efficiency of the catalyst reaches great importance, and isocyanate and polyols quickly crosslink to form a polyurethane network structure. Due to the rapid reaction rate, the release of VOC also increased accordingly, but the total amount is still far lower than that of traditional catalysts. <\/p>\n<\/li>\n<\/ul>\n2. Specific mechanisms to reduce VOC emissions<\/strong><\/h4>\n8154 Catalyst effectively reduces VOC emissions in the polyurethane production process through delayed catalytic mechanism. Specifically, its mechanism to reduce VOC emissions can be explained from the following aspects:<\/p>\n \n- \n
Inhibit premature reactions<\/strong>: Traditional catalysts can be activated quickly at room temperature, resulting in cross-linking reactions between isocyanate and polyol immediately after mixing. ThisThe \ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd The 8154 catalyst inhibits cross-linking reaction at room temperature through a delayed catalytic mechanism, reduces the generation of by-products, and thus reduces VOC emissions. <\/p>\n<\/li>\n- \n
Optimized reaction conditions<\/strong>: The activation temperature range of 8154 catalyst is 60-80\u00b0C, and this temperature range is exactly the appropriate reaction conditions in polyurethane production. Within this temperature range, the catalyst can fully exert its catalytic effect, promote the efficient reaction between isocyanate and polyol, and avoid the release of VOC caused by excessive reaction at high temperatures. Research shows that using 8154 catalyst can reduce VOC emissions by 30%-50% under the same conditions. <\/p>\n<\/li>\n- \n
Reduce side reactions<\/strong>: The delayed catalytic mechanism of 8154 catalyst not only inhibits premature reactions, but also reduces the occurrence of side reactions. Traditional catalysts are prone to trigger side reactions at high temperatures, such as the autopolymerization of isocyanate or reaction with moisture in the air, which will produce more VOCs. The 8154 catalyst avoids the occurrence of side reactions by precisely controlling the activation time and temperature, and further reduces VOC emissions. <\/p>\n<\/li>\n- \n
Improving reaction efficiency<\/strong>: The efficient catalytic performance of the 8154 catalyst makes the polyurethane reaction more thoroughly and reduces unreacted raw material residues. Unreacted raw materials may decompose or evaporate during subsequent treatment, becoming one of the sources of VOC. Therefore, the use of 8154 catalyst can improve the reaction efficiency, reduce raw material waste, and thus reduce VOC emissions. <\/p>\n<\/li>\n<\/ul>\n3. Experimental verification and data analysis<\/strong><\/h4>\nTo verify the effectiveness of the 8154 catalyst in reducing VOC emissions, the researchers conducted several experiments and collected a large amount of data.

The specific data are shown in the following table:<\/p>\n \n\nTemperature (\u00b0C)<\/th>\n | Reaction rate (min)<\/th>\n | VOC release (mg\/m\u00b3)<\/th>\n<\/tr>\n | \n\n50<\/td>\n | 30<\/td>\n | 80 \u00b1 10<\/td>\n<\/tr>\n | \n60<\/td>\n | 20<\/td>\n | 60 \u00b1 5<\/td>\n<\/tr>\n | \n70<\/td>\n | 15<\/td>\n | 50 \u00b1 3<\/td>\n<\/tr>\n | \n80<\/td>\n | 10<\/td>\n | 40 \u00b1 2<\/td>\n<\/tr>\n | \n90<\/td>\n | 5<\/td>\n | 70 \u00b1 10<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Experiments show that the 8154 catalyst has an excellent catalytic efficiency in the temperature range of 60-80\u00b0C, and the release of VOC is also low.

According to an internal report from Toray, after using the 8154 catalyst, the factory’s VOC emissions dropped significantly, meeting the requirements of Japanese environmental regulations. In addition, product quality has also been significantly improved, especially in terms of foam density and mechanical properties. <\/p>\n Dongray pointed out in a technical report that the delayed catalytic mechanism of 8154 catalyst makes the reaction process more controllable, avoiding premature crosslinking reactions, thereby reducing the generation of by-products.

We will compare the catalytic performance, VOC emissions, reaction conditions, product performance and other dimensions, and combine experimental data and literature to reveal the unique advantages of 8154 catalyst. <\/p>\n 1. Comparison of catalytic properties<\/strong><\/h4>\n Traditional catalysts (such as cinnamate, diacetyl tin, etc.) can be activated quickly at room temperature, resulting in a cross-linking reaction between isocyanate and polyol immediately after mixing. Although these catalysts have high catalytic efficiency, due to the rapid reaction speed, it is easy to cause side reactions, resulting in large-scale release of VOC. In contrast, the 8154 catalyst inhibits cross-linking reaction at room temperature through a delayed catalytic mechanism, avoiding premature curing and VOC release. Within the temperature range of 60-80\u00b0C, the 8154 catalyst gradually releases the active center and begins to play a catalytic effect. The reaction rate is moderate, which not only ensures efficient catalytic performance, but also avoids the occurrence of side reactions. <\/p>\n \n\nCatalytic Type<\/th>\n | Activation temperature (\u00b0C)<\/th>\n | Activation time (min)<\/th>\n | Catalytic Efficiency (%)<\/th>\n<\/tr>\n | \n\nShinyasin<\/td>\n | 25-30<\/td>\n | 1-2<\/td>\n | 90<\/td>\n<\/tr>\n | \nDiocyanine Dibutyltin<\/td>\n | 25-30<\/td>\n | 1-2<\/td>\n | 95<\/td>\n<\/tr>\n | \n8154 Catalyst<\/td>\n | 60-80<\/td>\n | 5-15<\/td>\n | 98<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n From the table above, it can be seen that the activation temperature of the 8154 catalyst is higher, the activation time is longer, but the catalytic efficiency is higher. This is because the delayed catalytic mechanism of the 8154 catalyst makes the reaction process more controllable, avoiding premature crosslinking reactions, thereby improving the catalytic efficiency. <\/p>\n 2. VOC emission comparison<\/strong><\/h4>\n Traditional catalysts can be activated quickly at room temperature, resulting in a cross-linking reaction between isocyanate and polyol immediately after mixing, producing a large number of by-products, such as carbon dioxide, A, Dimethyl, etc., thereby increasing VOC emissions. In contrast, the 8154 catalyst inhibits cross-linking reaction at room temperature through a delayed catalytic mechanism, reduces the generation of by-products, thereby significantly reducing VOC emissions. Experimental data show that using 8154 catalyst can reduce VOC emissions by 30%-50%. <\/p>\n \n\nCatalytic Type<\/th>\n | VOC emissions (mg\/m\u00b3)<\/th>\n<\/tr>\n | \n\nShinyasin<\/td>\n | 120 \u00b1 10<\/td>\n<\/tr>\n | \nDiocyanine Dibutyltin<\/td>\n | 110 \u00b1 10<\/td>\n<\/tr>\n | \n8154 Catalyst<\/td>\n | 60 \u00b1 5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n From the table above, it can be seen that the VOC emissions of 8154 catalyst are significantly lower than those of traditional catalysts, and have obvious environmental protection advantages. <\/p>\n 3.

In contrast, the activation temperature of the 8154 catalyst is higher and the activation time is longer, making the reaction conditions more mild and avoiding the release of VOC caused by excessive reaction at high temperatures. In addition, the efficient catalytic performance of the 8154 catalyst makes the reaction process more thorough, reducing unreacted raw material residues and further reducing VOC emissions. <\/p>\n \n\nCatalytic Type<\/th>\n | Optimal reaction temperature (\u00b0C)<\/th>\n | Good reaction time (min)<\/th>\n | VCO release (mg\/m\u00b3)<\/th>\n<\/tr>\n | \n\nShinyasin<\/td>\n | 80-90<\/td>\n | 5-10<\/td>\n | 120 \u00b1 10<\/td>\n<\/tr>\n | \nDiocyanine Dibutyltin<\/td>\n | 80-90<\/td>\n | 5-10<\/td>\n | 110 \u00b1 10<\/td>\n<\/tr>\n | \n8154 Catalyst<\/td>\n | 60-80<\/td>\n | 10-15<\/td>\n | 60 \u00b1 5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n From the table above, it can be seen that the 8154 catalyst has a lower reaction temperature and a longer reaction time, but the VOC emissions are significantly reduced, and it has better control of reaction conditions. <\/p>\n 4.
