Study on the stability of conductive cloth tape at high temperature

Brief introduction

In the fields of modern industry and electronic technology, the application of conductive cloth tape is becoming increasingly widespread. However, as many devices operate in high-temperature environments, the stability of conductive cloth and tape at high temperatures has become a key consideration factor. This article will delve into the stability of conductive cloth tape at high temperatures and present the findings of Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand conductive cloth tapeAnalyze as an example.

（1） The basic structure and principle of conductive cloth tape

Conductive cloth tape is mainly composed of conductive cloth, adhesive, etc. Conductive cloth is made by covering a layer of conductive metal (such as copper, nickel, etc.) on polyester fibers through chemical plating or electroplating processes, and the adhesive is responsible for sticking the conductive cloth to the desired surface. This structure enables conductive tape to have good conductivity and meet certain adhesive and fixing requirements.

（2） The challenge of high temperature environment on conductive cloth and tape

High temperature environments may have various effects on conductive cloth and tape, such as changes in the performance of adhesives, leading to a decrease in adhesive strength; The metal coating on the conductive cloth may undergo oxidation, affecting its conductivity; The overall structure of the tape may be damaged due to thermal expansion and other reasons.

2、 Stability analysis of Yanbo brand conductive cloth tape at high temperature

（1） Experimental data and testing methods

Advanced Institute (Shenzhen) Technology Co., LtdA series of high-temperature stability tests were conducted on the conductive cloth tape of Yanbo brand.

1. Temperature resistance range test
   • Using a thermal cycling test chamber, place the sample of Yanbo brand conductive cloth tape inside. The test temperature range is from -40 ° C to 150 ° C, with a certain heating rate (such as 5 ° C/min), held at each set temperature point for a certain period of time (such as 30 minutes), and then cooled down at the same cooling rate.
   • After multiple cycles, it was found that the physical properties of the Yanbo brand conductive cloth tape (such as tensile strength, adhesive force, etc.) remained basically unchanged within the temperature range below 120 ° C. When the temperature reaches 150 ° C, the decrease in tensile strength is about 10%, and the decrease in adhesive force is about 15%. These data indicate that the research platinum brand conductive cloth tape has good stability within a certain high temperature range.
2. Conductivity testing
   • Measure the electrical resistivity of Yanbo brand conductive tape using a four probe tester at different temperatures.
   • At room temperature (25 ° C), its resistivity is 0.01 Ω· cm. When the temperature rises to 100 ° C, the resistivity only increases to 0.012 Ω· cm, with a rise of about 20%. This indicates that the conductive cloth tape of Yanbo brand can still maintain good conductivity at high temperatures.

Compared with some other conductive cloth tapes on the market,Yanbo brand conductive cloth tapeIt shows significant advantages in high temperature stability.

1. Test results of some competitors
   • We selected common A and B brand conductive cloth tapes in the market for the same high temperature test.
   • At 100 ° C, the tensile strength of A brand conductive cloth tape decreases by about 20%, while that of Yanbo brand conductive cloth tape is only 5%; The resistivity increase of B brand conductive cloth tape is about 30%, while that of Yanbo brand conductive cloth tape is 20%.
2. Analysis of Advantages and Reasons
   • The adhesive of Yanbo brand conductive cloth tape adopts a special formula, and its molecular structure has better stability at high temperatures, which can effectively resist phenomena such as thermal decomposition.
   • The metal coating of conductive cloth has higher quality and adopts advanced electroplating technology, resulting in a more uniform and dense coating. It can better prevent oxidation at high temperatures, thereby ensuring conductivity and overall structural stability.

3、 Factors affecting the high-temperature stability of Yanbo brand conductive cloth tape

（1） Adhesive Composition and Properties

1. Ingredient characteristics
   • The adhesive of Yanbo brand conductive cloth tape contains special high-temperature resistant polymer components, which can form stable cross-linked structures at high temperatures. For example, a certain proportion of polyimide polymer is added, which has excellent high-temperature resistance and can withstand high temperatures without softening or decomposition.
2. Performance Performance
   • This adhesive can maintain a certain degree of flexibility at high temperatures and will not quickly harden or become brittle due to temperature increase. This allows the tape to adhere tightly to the surface of the object being glued in high temperature environments, maintaining a good bonding effect.

（2） Quality and Structure of Conductive Cloth

1. Quality of conductive fabric
   • Yanbo brand conductive cloth tapeThe conductive fabric used has a high-quality polyester fiber base and good heat resistance. At the same time, the purity and thickness of the metal coating are also precisely controlled. Compared to the thinner coating of some ordinary conductive cloth tapes, it can provide better protection at high temperatures and prevent internal fibers from being affected by high temperatures.
2. Structural advantages
   • The fiber structure of conductive cloth is tightly arranged, which helps to reduce the damage of thermal expansion to the overall structure at high temperatures. A tight structure also facilitates heat conduction and avoids performance degradation caused by local overheating.

4、 Conclusion

In summary, the research platinum brand conductive cloth tape of Advanced Institute (Shenzhen) Technology Co., Ltd. has good stability at high temperatures. According to experimental data, within a certain high temperature range, the changes in its physical and electrical properties are relatively small, and it has significant advantages compared to other similar products. This is mainly due to the special composition and properties of its adhesive, as well as the high-quality and reasonable structure of the conductive fabric. In future applications, the research platinum brand conductive cloth tape has broad prospects for electronic device connection, electromagnetic shielding, and other fields in high-temperature environments. However, with the continuous development of technology, the demand for the stability and other special properties of conductive tape at higher temperatures will continue to increase, and further research and optimization are needed.
