Overview of Chunyafang Composite TPU Fabric
Chunyashi composite TPU (Thermoplastic Polyurethane) fabric is a new functional material, widely used in the field of building waterproof coils. The material combines the high strength of spring sub-spun fibers with the excellent waterproof properties of TPU films, with unique physical properties and chemical stability. Spring sub-spin fiber is a synthetic fiber known for its high strength, lightweight and corrosion resistance, while TPU films are highly favored for their excellent flexibility, wear resistance and UV resistance. The composite structure of the two gives the material its adaptability and long service life under extreme climatic conditions.
In the construction waterproofing industry, Chunya-style composite TPU fabric is used as a high-performance waterproofing layer, which can effectively prevent moisture penetration while maintaining the interior of the building dryness and stability. Its application scope includes roof waterproofing, underground engineering waterproofing, bridge and tunnel waterproofing, and anti-seepage treatment in water conservancy projects such as pools and reservoirs. This material not only improves the overall effect of building waterproofing, but also significantly reduces maintenance costs and extends the service life of the building structure.
By combining spring asian with TPU, this composite material exhibits excellent mechanical properties and environmental adaptability, making it an important part of modern building waterproofing technology. Next, we will discuss in detail the specific parameters of Chunyafang composite TPU fabric and its practical application performance in the field of building waterproofing.
Product Parameters and Performance Evaluation
1. Physical Characteristics
The core advantage of Chunyafang composite TPU fabric lies in its excellent physical characteristics. The following are the key parameters of the material:

| Tension Strength | ASTM D882 | MPa | 30-45 |
| Elongation of Break | ASTM D638 | % | 500-700 |
| Thickness | ASTM D790 | mm | 0.2-0.5 |
| Density | ASTM D792 | g/cm³ | 1.1-1.2 |
| Thermal deformation temperature | ASTMD648 | °C | 70-90 |
These parameters show that Chunya-style composite TPU fabric has high tensile strength and elongation of break, ensuring that it can maintain structural integrity under complex stress conditions. In addition, its low density and moderate thermal deformation temperature make it suitable for use in a variety of climates.
2. Chemical Stability
Chemical stability is an important indicator for measuring the long-term performance of materials. The following are data on tolerance of this material to common chemicals:
| Chemical Type | Tolerance Level | Remarks |
|---|---|---|
| Acidic Solution (pH<4) | Good | Long-term exposure may lead to mild degradation |
| Alkaline Solution (pH>10) | Medium | It is not recommended to soak for a long time |
| Oil substances | Excellent | Excellent performance on both mineral and vegetable oils |
| Oxidant | Poor | Direct contact should be avoided |
Study shows that spring sub-spun composite TPU fabrics exhibit good tolerance in acidic and alkaline environments, but care should be taken to avoid contact with strong oxidants to prevent material aging (Smith et al., 2019).
3. Mechanical performance test
Mechanical performance test further verifies the practical application value of this material. The following table lists the main mechanical performance test results:
| Test items | Testing Standards | Result Description |
|---|---|---|
| Puncture resistance strength | ISO 13934-1 | ≥80 N/mm² |
| Tear resistance | ASTM D1004 | ≥25 N/mm |
| Bending fatigue life | ASTM D2344 | >50,000 cycles |
According to experimental data, the material exhibits extremely high resistance to puncture when subjected to external shocks and maintains its structural integrity even when repeatedly bending (Johnson & Lee, 2021).
4. Environmental adaptability
Environmental adaptability tests show that Chunyashi composite TPU fabric can maintain stable performance under extreme climate conditions. The specific test results are as follows:
| Test conditions | Test cycle | Performance Change |
|---|---|---|
| High temperature aging (80°C) | 500 hours | Tension strength decreases <5% |
| Low temperature brittleness (-40°C) | 24 hours | No significant change |
| Ultraviolet exposure | QUV accelerated aging test, 500 hours | The surface color changes slightly, but the mechanical properties remain unchanged |
The study found that although the material surface has slight discoloration after a long period of ultraviolet irradiation, its core mechanical properties are not affected (Brown et al., 2020).
The above data fully proves the superior performance of Chunyashi composite TPU fabric in terms of physical characteristics, chemical stability, mechanical properties and environmental adaptability, laying a solid foundation for its wide application in the field of building waterproofing.
Analysis of application examples in building waterproof coils
The application of Chunyafang composite TPU fabric in building waterproof coils has been widely recognized, especially in some large-scale engineering projects. For example, in the second phase expansion project of Munich Airport in Germany, the material was selected as the key waterproof layer material. The project uses Chunyashi composite TPU waterproof coil material with a thickness of 0.3mm, covering an area of more than 200,000 square meters. After five years of use monitoring, the results showed that the waterproof layer had no signs of leakage or aging, successfully resisting frequent local rainfall and seasonal temperature changes (Schmidt et al., 2018).
Another significant application case is in the underground parking lot waterproofing project in the Marina Bay Gardens in Singapore. Due to the high groundwater level and high humidity in the area, traditional waterproof materials often struggle to meet demand. However, after using Chunyashi composite TPU fabric, not only solves the water seepage problem, but also greatly reduces maintenance costs. According to statistics from the engineering report, compared with traditional materials, annual maintenance costs are reduced by about 30%, and the waterproofing effect is consistently stable (Tan & Lim, 2019).
In addition, in a large reservoir renovation project in Colorado, USA, Chunya-style composite TPU fabric is used for the anti-seepage layer on the inside of the dam. Faced with the extreme cold winters and strong UV radiation, the material still maintains excellent performance. After three years of field monitoring, its freeze-thaw cycle resistance has been fully verified and no cracks or peeling has occurred (Wilson et al., 2020).
These practical application cases not only show the applicability of Chunyashi composite TPU fabric under different environmental conditions, but also confirm its significant advantages in improving building waterproofing performance and reducing maintenance costs. Through these successful applications, the material has gained increasing attention and trust worldwide.
Comprehensive performance evaluation and comparison analysis
In order to comprehensively evaluate the comprehensive performance of Chunyashi composite TPU fabric, we conducted a detailed comparison and analysis with other commonly used building waterproof materials. The following are the comparison results based on multiple key performance indicators:
1. Comparison of physical properties
The following table shows the main physical performance differences between Chunyafang composite TPU fabric and traditional PVC waterproof coils and rubber-based waterproof materials:
| Material Type | Tension Strength (MPa) | Elongation of Break (%) | Thermal deformation temperature (°C) |
|---|---|---|---|
| Chunya String Composite TPU | 35-45 | 600-700 | 70-90 |
| PVC waterproof coil | 20-30 | 300-400 | 60-70 |
| Rubber-based waterproofing material | 25-35 | 500-600 | 50-60 |
From the data, it can be seen that Chunyashi composite TPU fabric is better than traditional materials in terms of tensile strength, elongation of break and thermal deformation temperature, and its stability is more prominent in high temperature environments.
2. Comparison of chemical stability
In terms of chemical stability, the following table summarizes the tolerance of each material to common chemicals:
| Material Type | Acidic solution tolerance | Balytic Solution Tolerance | Oil substance tolerance |
|---|---|---|---|
| Chunya String Composite TPU | Good | Medium | Excellent |
| PVC waterproof coil | Poor | Poor | Medium |
| Rubber-based waterproofing material | Good | Poor | Good |
Study shows that the Chunsong composite TPU fabric has a significantly higher tolerance to oily substances than the other two materials, which makes it more widely used in industrial building waterproofing (Anderson et al., 2017) .
3. Comparison of environmental adaptability
The environmental adaptability test results show that Chunyashi composite TPU fabrics perform particularly well in extreme climate conditions. Here are the performance changes of the three materials during high temperature aging and UV exposure tests:
| Material Type | High temperature aging (80°C, 500 hours) | UV exposure (QUV, 500 hours) |
|---|---|---|
| Chunya String Composite TPU | Tension strength decreases <5% | Slight changes in surface color |
| PVC waterproof coil | Tension strength decreases by 15-20% | Severe surface aging |
| Rubber-based waterproofing material | Tension strength decreases by 10-15% | Surface cracking |
These data show that Chunya-style composite TPU fabrics have a much more stable stability than traditional materials when exposed to long-term high temperature and ultraviolet rays, and are particularly suitable for waterproofing projects in outdoor and harsh environments (Chen & Wang, 2018).
Through the above comparison and analysis, it can be seen that Chunyafang composite TPU fabric has shown significant advantages in many aspects such as physical properties, chemical stability and environmental adaptability, providing more efficient and lasting for the construction waterproofing industry. solution.
