How high temperature can PET copper plated film withstand

PET (Polyethylene terephthalate)As a widely used engineering plastic, it has been widely applied in multiple fields due to its excellent physical and mechanical properties and chemical stability. PET copper plated film is made by chemically plating copper on the surface of PET material, which endows it with conductivity, thermal conductivity and other properties, further expanding the application range of PET materials.Advanced Institute (Shenzhen) Technology Co., LtdAs a specialist in thermal conductive materials, shielding materialsConductive silver pasteEnterprises engaged in the research and production of functional materials have attracted significant attention in the market for their PET copper plated films. So, how high temperature can PET copper plated film withstand?

High temperature resistance of PET material

Firstly, we need to understandPET materialIts inherent high temperature resistance. The melting point of PET film is about 260 ° C, indicating its strong high-temperature resistance in a short period of time. Under normal use, PET film can withstand temperatures ranging from 70 ° C to 90 ° C. Within this temperature range, PET film will not undergo significant deformation or melting, and can maintain its original physical properties. Therefore, in general packaging applications, PET film can meet the requirements of daily use.

However, when the temperature exceeds 90 ° C, PET film may begin to soften, leading to deformation and loss of its original mechanical strength. When the temperature exceeds 120 ° C, PET film may melt and lose its original structure and function. This means that special attention needs to be paid to the application of PET film in high-temperature environments to avoid accidents or losses.

High temperature resistance of PET copper plated film

On the basis of inheriting the excellent physical and mechanical properties of PET material, PET copper plated film has been treated with chemical copper plating to possess characteristics such as conductivity and thermal conductivity. However, copper plating treatment may affect the high temperature resistance of PET materials. Therefore, understanding the high temperature resistance of PET copper plated film is crucial for its application.

Through experimental data comparison, we can find that the high temperature resistance of PET copper plated film is different from that of PET material. On the one hand, the copper plating layer increases the thermal stability of PET material, allowing it to maintain good conductivity at high temperatures. On the other hand, the copper plating layer may also become an area of thermal stress concentration, leading toPET copper plated filmIt is more prone to deformation or damage at high temperatures.

According to data provided by Advanced Institute (Shenzhen) Technology Co., Ltd., PET copper plated film can withstand temperatures up to 120 ° C under long-term use. This data is consistent with the long-term upper temperature limit of PET material, indicating that copper plating treatment did not significantly reduce the high temperature resistance of PET material. However, it should be noted that the electrical properties of PET copper plated films may be affected at high temperatures and frequencies, resulting in poor corona resistance.

Data comparison and analysis

To gain a more intuitive understandingPET copper plated filmWe can compare its high temperature resistance performance with PET materials and other conductive materials. Here are some key data comparisons:

• PET material: The melting point is about 260 ° C, the normal operating temperature range is 70 ° C to 90 ° C, and the upper limit of long-term use temperature is 120 ° C.
• PET copper plated film: Long term use temperature can reach 120 ° C, and electrical properties may be affected at high temperatures and frequencies.
• Other conductive materials, such as electrolytic copper foil, may have higher thickness and cost than PET copper plated film, but their high temperature resistance may be stronger.

By comparison, it can be seen that PET copper plated film is comparable to PET material in terms of high temperature resistance, but has additional characteristics such as conductivity and thermal conductivity. This makes PET copper plated film have broad application prospects in fields such as electronics, optics, and conductivity.

conclusion

in summary,PET copper plated filmCan withstand temperatures up to 120 ° C under long-term use. However, it should be noted that its electrical performance may be affected at high temperatures and frequencies. Therefore, when applying PET copper plated film, it is necessary to evaluate and select according to specific usage environments and requirements. As a professional manufacturer of functional materials, Advanced Institute (Shenzhen) Technology Co., Ltd.'s PET copper plated film is at the forefront of the industry in terms of quality and technology, providing users with a reliable choice.
