Hot-melt PI film (polyimide
Features
1. Excellent heat resistance: It can be used for a long time in high-temperature environments above 250℃, and can withstand even higher temperatures for a short period without deformation, with stable performance.
2. Excellent mechanical properties: Tensile strength can reach over 100MPa, and it also features good wear resistance and tear resistance, being tough and durable.
3. Excellent insulation: With a stable dielectric constant and high insulation resistance, it is an excellent electrical insulating material that can effectively prevent short circuits and current leakage in circuits.
It has significant applications in wires and cables, mainly reflected in the following aspects:
1. Insulating layer
Hot-melt PI has excellent electrical insulation performance, can withstand high voltage, effectively prevent current leakage inside wires and cables and external electromagnetic interference, improve the insulation reliability of wires and cables, and ensure their safe and stable operation in various complex electrical environments.
2. Shielding layer
Hot-melt PI can be used as a shielding material to shield the signals transmitted by wires and cables, reducing signal attenuation and interference from external electromagnetic signals, ensuring the quality and stability of signal transmission. It is particularly suitable for high-speed data transmission cables and high-frequency signal cables.
3. Hot-melt PI film can be used for the winding of wires and cables. It not only provides good insulation and protection but also has a low coefficient of friction. During the winding process, it can reduce damage to the surface of the wires and cables. Meanwhile, the PI film after winding can closely adhere to the surface of the cables, improving the overall performance of the cables.
