Polyimide cable & Wire | Polyimide Magnet Wire | PI cable
Extruded polyimide cable is a high-performance cable that is mainly used in applications that require high reliability and durability. Polyimide (PI wire), as a high-performance thermoplastic resin, performs particularly well in high-temperature environments due to its excellent electrical properties, chemical stability and mechanical strength. Extruded polyimide cable is an ideal choice for many high-tech applications due to its unique properties. However, it should be noted that the cost of this type of cable is relatively high, so it is usually only selected when there are strict requirements for cable performance. Here are some details about extruded polyimide cables:
Polyimide Magnet Wire PI Extruded Cable Insulation Material
Polyimide: This is a very heat-resistant material that can maintain its physical and electrical properties at high temperatures. Polyimide is often used to make the insulation layer of cables to protect the internal conductor from the external environment.
Extrusion process: Extrusion is the process of passing a heated polymer through a die (die) to form the desired shape. For polyimide cables, the extrusion process ensures that the insulation layer is evenly covered on the conductor and can form a consistent thickness on complex geometries.

The conductor in extruded polyimide cable is usually a metal wire, such as copper or silver-plated copper, which has good conductivity.
Polyimide magnet wire PI extruded cable structural features
Flat wire structure: Some polyimide cables may adopt a flat wire structure, which allows them to be arranged more closely together, improve space utilization, and also help improve heat dissipation.
Multi-layer insulation: In order to improve the voltage resistance and service life of the cable, a multi-layer polyimide insulation design may be used.
Polyimide magnet wire PI extruded cable application field
Aerospace: Due to its excellent temperature resistance and chemical corrosion resistance, polyimide cables are widely used in avionics equipment.
Industrial automation: In industrial equipment that needs to move frequently or be exposed to harsh environments, polyimide cables are favored for their durability and reliability.
Medical equipment: This type of cable is also needed in some precision medical equipment to ensure accurate signal transmission.
8 advantages of polyimide electromagnetic wire PI extruded cable
- High temperature resistance: Polyimide cable can work stably in high temperature environment, with a maximum operating temperature of 250°C to 265°C.
- Chemical stability: Good tolerance to a variety of chemicals, suitable for chemical industrial environments.
- Low smoke and halogen-free: The amount of smoke produced during combustion is low and does not contain halogen compounds, which is friendly to human health and the environment.
- Flame retardant: It has good flame retardant properties and is suitable for applications requiring flame retardant properties.
- Flexibility: Even under low temperature conditions, polyimide cable can still maintain good flexibility, which is easy to bend and install.
- Scratch resistance: Polyimide extruded wire has better scratch resistance than polyimide wrapped wire, which can effectively prevent damage to the outer skin of the wire and extend the service life of the wire.
- Super strong adhesion: Polyimide extruded wire has super strong insulation adhesion due to its special process advantages. This not only has strong stability for signal transmission, but also no “shrinkage” phenomenon will occur at the joint, ensuring the safe operation of the device.
- Low dielectric loss: For some medical devices that need to transmit high-frequency signals, low dielectric loss is very important. Polyimide extruded wire has a lower dielectric constant and lower dielectric loss, which ensures the accuracy and stability of signal transmission and reduces signal attenuation and interference.
Technical specifications of polyimide electromagnetic wire PI extruded cable
Operating temperature range: Polyimide cables can usually withstand a wide range of operating temperatures, from low temperatures (such as -55°C) to high temperatures (such as +260°C), which makes them very suitable for use under extreme conditions.
Voltage level: According to different application requirements, polyimide cables can be designed into products with different voltage levels, ranging from hundreds of volts to thousands of volts.
Flame retardant properties: Some polyimide cables will add flame retardants or use other technical means to make them flame retardant, so as to slow down the spread of fire in the event of a fire.
Other characteristics of polyimide electromagnetic wire PI extruded cable
Bending radius: Due to the flexibility of polyimide cables, they have a small minimum bending radius, which means that they can be installed in a limited space.
Radiation resistance: In some special application scenarios, such as the nuclear industry, polyimide cables can provide a certain degree of radiation resistance.
Abrasion resistance: The polyimide material on the outer layer of the cable has good abrasion resistance and is suitable for use in environments with more friction.
Manufacturing process of polyimide electromagnetic wire PI extruded cable
Multi-step coating: During the production process, the conductor is usually coated with polyimide insulation material multiple times to increase its insulation strength and durability.
Curing treatment: After coating, the cable needs to undergo high-temperature curing treatment to ensure that the performance of the insulation material is in the best state.
Installation and maintenance of polyimide electromagnetic wire PI extruded cable
Easy installation: Although polyimide cables have high strength and durability, the installation process is relatively simple due to their flexible design.
Low maintenance cost: Due to their robustness and long life, polyimide cables require less maintenance after installation, reducing long-term operating costs.
Emerging applications of polyimide electromagnetic wire PI extruded cables
With the development of technology, extruded polyimide cables are also constantly expanding new application areas. For example, in the power system of new energy vehicles, in order to cope with the high voltage and high temperature environment in motors and battery management systems, polyimide cables have shown great potential. In addition, this type of high-performance cable is also increasingly used in wind power generation, solar power generation and other renewable energy projects.
Extruded polyimide cables play an important role in multiple industries due to their superior performance, and with the advancement of technology, more innovative applications will appear in the future.
