Detailed explanation of features
1. Low Odor Design
The core advantage of ZF-11 is its “low odor” characteristics. Traditional polyurethane catalysts usually contain a large number of volatile amine substances that easily decompose under high temperature conditions and release a pungent odor. Through its special molecular structure design, ZF-11 greatly reduces the volatility of amine substances, thereby significantly reducing the odor during the production process.
2. High-efficiency catalytic performance
ZF-11 can accurately control the speed and direction of the polyurethane foaming reaction to ensure uniform and stable foam generation. This efficient catalytic performance not only improves the mechanical strength of the product, but also reduces residual odor caused by incomplete reactions.
3. Environmentally friendly

How to work: Unveil the mystery of ZF-11
The basic role of catalyst
To understand the working principle of ZF-11, we first need to understand the basic role of catalysts in the polyurethane foaming process. Polyurethane foaming is a complex chemical reaction process, which mainly includes the following steps:
- Reaction of isocyanate and polyol: Formation of carbamate groups.
- Hydrolysis reaction: Water reacts with isocyanate to form carbon dioxide gas, which promotes the expansion of the foam.
- Crosslinking reaction: Form a three-dimensional network structure, giving the foam excellent mechanical properties.
In this process, the catalyst acts like a “traffic commander”, responsible for guiding and accelerating the occurrence of the above reactions and ensuring that the entire system is carried out in accordance with the predetermined goals.
ZF-11’s unique mechanism
The reason why ZF-11 can achieve low odor effect is mainly due to the following unique design:
1. Molecular Structure Optimization
ZF-11 uses a special amine compound modification technology to shield the volatile channels of small-molecular amines by introducing macromolecular groups. This is like putting a “protective suit” on each small molecule, making it difficult for it to escape into the air, thus greatly reducing the production of odor.
2. Dual catalytic function
In addition to the traditional isocyanate-polyol reaction, ZF-11 also has the ability to promote crosslinking reactions. This “two-pronged” catalytic strategy not only improves the reaction efficiency, but also reduces residual substances that are not involved in the reaction, further reducing the source of odor.
3. Enhanced thermal stability
In the process of polyurethane foaming, the temperature is often as high as 100°C. Under such extreme conditions, traditional catalysts may decompose, releasing more volatile substances. After special treatment, ZF-11 can maintain stable catalytic performance even under high temperature environments, avoiding the increase in odor caused by decomposition.
Experimental Verification
To verify the actual effect of ZF-11, the researchers designed a series of comparison experiments. Under the same formulation and process conditions, polyurethane foam samples were prepared using ZF-11 and other common catalysts, respectively, and their odor grade and VOC release were detected. Results show:
| Sample number |
Use catalyst |
Odor level |

?level 1 |
45 |
| B |
Current Catalyst |
Level 3 |
150 |
| C |
High-end imported catalyst |
Level 2 |

It can be seen that the performance of ZF-11 in odor control is indeed impressive.
Application Scenario: From the laboratory to the production line
Furniture Manufacturing Field
In the furniture manufacturing industry, polyurethane foam is widely used in the production of soft furniture such as mattresses, sofa cushions, etc. However, due to the limitations of traditional catalysts, many products emit obvious odors in the early stages of use, seriously affecting consumers’ willingness to purchase. After adopting ZF-11, it not only significantly reduces the odor, but also improves the comfort and durability of the foam, truly realizing “both internal and external cultivation”.
Automotive interior field
As people’s requirements for air quality in cars continue to improve, the environmental protection performance of car interior materials is receiving more and more attention. With its excellent low odor properties and stable catalytic properties, the ZF-11 has become the preferred solution for many well-known automakers. For example, an international car company has fully adopted polyurethane seat foam produced based on ZF-11 in its new model. User feedback is generally good, saying that there is almost no odor in the car.
Building insulation field
In the field of building insulation, polyurethane rigid foam is highly favored for its excellent thermal insulation properties. However, traditional production processesThe volatile substances produced in the project may pose a threat to the health of construction workers. By introducing ZF-11, it can not only reduce odor pollution, but also shorten the curing time, improve construction efficiency, and inject new vitality into the development of the industry.
Optimization strategy: Make the effect a step further
Although the ZF-11 itself has many advantages, in actual applications, appropriate adjustments need to be made in accordance with specific circumstances to achieve the best results. Here are some practical optimization strategies:
1. Reasonable selection of formula ratio
There may be differences in the demand for catalysts in different application scenarios. For example, in soft foam production, it is recommended to control the addition amount of ZF-11 between 0.5% and 1% of the total weight; in hard foam production, it can be appropriately increased to 1.5%-2% according to actual conditions. By precisely controlling the amount of addition, the catalytic effect can be guaranteed without causing waste.
2. Improve the mixing process
Mix uniformity is crucial to the quality of the final product. It is recommended to use a high-speed stirring equipment and ensure sufficient stirring time to fully disperse the ZF-11 particles. In addition, it is also possible to consider introducing an online monitoring system to monitor various parameters in the mixing process in real time to ensure the quality consistency of each batch of products.
3. Strengthen post-processing
Even if low-odor catalyst is used, some residual odors may still be released gradually after the product is formed. To this end, appropriate post-treatment measures can be taken, such as vacuum degassing, high-temperature maturation, etc., to further reduce the odor level. At the same time, pay attention to maintaining good ventilation conditions, which will help accelerate the dissipation of odor.
4. Continuous technological innovation
Technical progress is endless. In the future, with the continuous emergence of new materials and new processes, ZF-11 is also expected to usher in more room for improvement. For example, by introducing nanotechnology or intelligent responsive materials, further improving their catalytic efficiency and environmental performance will bring greater changes to the polyurethane industry.
