The basic characteristics and working principle of DC-193
DC-193 is a multifunctional stabilizer specially used for the production of polyurethane foam. Its core function is to regulate the bubble distribution and structural stability during the foam formation process. To understand its specific functions, we first need to understand the basic production process of polyurethane foam and the role DC-193 plays in this process.
1. The generation mechanism of polyurethane foam
Polyurethane foam is a porous material produced by chemical reaction with polyols by isocyanates such as TDI or MDI. During this reaction, a foaming agent (usually water or other low boiling liquid) is introduced into the system, decomposing at high temperatures to produce carbon dioxide gas, thereby forming bubbles and promoting foam expansion. However, if the bubble distribution is unevenly or the wall film is insufficient, it may lead to excessive holes, collapse or even rupture inside the foam, affecting the performance of the final product.
2. The mechanism of action of DC-193
The main task of DC-193 is to solve the above problems. It works in the following ways:
-
Promote uniform distribution of bubbles
In the early stages of foam formation, DC-193 reduces the surface tension of the mixture, makes bubbles more likely to form and ensures that they are evenly dispersed throughout the system. This uniformity is crucial to ensure the density consistency and mechanical properties of the foam. -
Enhance the stability of foam wall film
Foam wall film is a film composed of polymer chains whose strength directly affects the foam's shape retention ability. DC-193 enhances the toughness of the wall membrane by regulating the interaction between polymer molecules and prevents premature rupture or merger of bubbles. -
Control foam expansion rate
If the foam expands too fast, it may lead to too loose internal structure; otherwise, it may limit the overall volume of the foam. DC-193 is able to effectively balance this process, ensuring that the foam expands within the appropriate range, resulting in the ideal density and hardness. -
Improve the processing performance of foam
In addition, DC-193 also has a certain lubrication effect, which can reduce the adhesion of foam in the mold, improve the demolding efficiency, and reduce the scrap rate during the production process.
III. Key parameters of DC-193
To better understand the functions of DC-193, we can refer to the typical parameters listed in the following table:
| parameter name | Unit | Typical value range | Description |
|---|---|---|---|
| Appearance | – | Colorless to light yellow transparent liquid | indicates that it is easy to mix with other raw materials and will not have adverse effects on the appearance of the final product. |
| Density | g/cm³ | 0.98–1.02 | determines the precise calculation of its dispersion and usage in the mixed liquid. |
| Viscosity | mPa·s | 50–100 | Affects its fluidity and uniformity in the reaction system. |
| Active ingredient content | % | ≥99 | High purity helps improve product stability and consistency. |
| pH value | – | 6.5–7.5 | Neutral range to avoid the risk of corrosion to other raw materials or equipment. |
IV. Examples of actual effect
Take a typical soft polyurethane foam as an example, after adding an appropriate amount of DC-193, its performance indicators will usually improve as follows:
| Performance metrics | Before Add | After adding | Improvement (%) |
|---|---|---|---|
| Foam density (kg/m³) | 35 | 30 | +14% |
| Compression Strength (kPa) | 20 | 25 | +25% |
| Resilience (%) | 50 | 60 | +20% |
| Dimensional stability (%) | ±2 | ±1 | +50% |
From these data, it can be seen that DC-193 not only improves the basic performance of the foam, but also enhances its reliability for long-term use.
To sum up, DC-193 has successfully solved common technical problems in polyurethane foam production with its excellent regulatory capabilities, laying a solid foundation for subsequent applications. Next, we will further explore its unique value in the electronic product packaging field.
Advantages of DC-193 in electronic product packaging
DC-193, as a polyurethane foam stabilizer, has become an ideal choice for electronic product packaging due to its unique performance characteristics. Below, we will discuss in detail how DC-193 can help electronic product packaging achieve efficient protection from several key aspects.
Improving buffer performance
Electronic products will inevitably encounter vibration and impact during transportation, so the cushioning performance of packaging materials is particularly important. DC-193 greatly improves its ability to absorb shock by optimizing the microstructure of polyurethane foam. For example, in an experiment, the foam treated with DC-193 can maintain its integrity when it withstands acceleration impacts of up to 20G, effectively protecting the internal electronic components from damage. This excellent cushioning performance is thanks to DC-193 Fine adjustments to the foam pore size and wall thickness ensure that the foam can quickly deform and quickly return to its original state when under pressure.
Enhance the compressive strength
In addition to buffering properties, packaging materials also need to have sufficient compressive strength to resist external pressure. DC-193 is equally outstanding in this regard. By increasing the density of the foam and improving its molecular structure, DC-193 significantly enhances the foam's compressive resistance. This means that the foam can keep its shape unchanged even when stacked, thus better protecting the electronics inside. For example, a well-known brand mobile phone manufacturer used foam material containing DC-193 in its packaging, and found that even if three layers of high are stacked in the warehouse, the foam did not show obvious deformation or damage.
Improving thermal stability
Electronic products are very sensitive to temperature changes, so the thermal stability of packaging materials is also a factor that cannot be ignored. DC-193 greatly improves its heat resistance by adjusting the crosslinking and crystallinity of the foam. In this way, the foam can maintain its physical properties and functionality even under extreme temperature conditions. For example, in one test, the foam containing DC-193 still maintained good elasticity and strength after repeated cycles from -40°C to 80°C, ensuring safe transportation of electronic products.
Environmental and Sustainability
After
, DC-193's performance in environmental protection cannot be ignored. As global awareness of environmental protection increases, more and more companies are beginning to pay attention to the recyclability and biodegradability of packaging materials. DC-193 is not only an environmentally friendly additive itself, but also reduces the use of raw materials by optimizing the foam structure, indirectly reducing resource consumption and environmental pollution. For example, a large electronics company successfully reduced its packaging waste by 30% by using DC-193-optimized foam materials, achieving a win-win situation of economic and environmental benefits.
To sum up, DC-193 fully demonstrates its important value in electronic product packaging by improving buffer performance, enhancing compressive strength, improving thermal stability and supporting environmental protection goals. These advantages not only meet the high standards of packaging materials for modern electronic products, but also contribute to the sustainable development of the industry.

In addition, the impact strength of the new foam is increased by about 30%, greatly reducing product damage during transportation.
Case 2: Shockproof packaging of laptops
For heavier and vulnerable electronic products such as laptops, shock resistance is one of the core requirements of packaging materials. A laptop manufacturer tried to replace the original EVA foam with foam containing DC-193. The test results show that the new foam showed excellent shock resistance in simulated drop tests, and its shock absorption effect was more than 25% higher than that of the original material. Especially after repeated drop tests, the foam still maintains its original form, showing extremely high durability and stability.
