PEEK insulated cables

• What is PEEK cable?

  Jun 09, 2025

    PEEK cable refers to electrical wiring that uses PEEK (Polyether ether ketone) as its insulating material. PEEK is a type of high-performance plastic known for its excellent mechanical strength, heat resistance, and chemical stability.One of the main features of PEEK is its high-temperature resistance. It can function in environments reaching up to 260°C (500°F) without losing its performance. This makes it especially useful in aerospace, automotive, energy, and medical industries, where equipment may be exposed to extreme heat for extended periods.Another strength of PEEK cable is its chemical resistance. It doesn’t break down easily in harsh environments that involve exposure to fuels, oils, acids, or radiation. Because of this, it’s often used in nuclear facilities and chemical plants, where both reliability and safety are critical. Additionally, PEEK wire cables resist hydrolysis, so they perform well even in humid or underwater conditions.PEEK cables are also known for their mechanical toughness. The insulation is hard and abrasion-resistant, so it can survive wear and friction over time. This durability also means fewer replacements and less maintenance—ideal for installations in hard-to-reach or mission-critical locations.In terms of electrical performance, PEEK has good dielectric properties, meaning it effectively insulates and minimizes signal loss. This makes it suitable for signal transmission, sensors, and high-frequency applications.Compared to standard plastic cables, PEEK cables are more expensive due to the cost of materials and processing. However, their long lifespan and reduced need for maintenance often justify the investment, especially in demanding environments where downtime is costly.In medical technology, PEEK is also used because it is biocompatible and sterilizable. PEEK insulated cables can be used in medical imaging devices, surgical tools, or implantable systems where reliability is essential.PEEK cable is a specialized product designed for harsh and high-stakes conditions. Whether it’s in a jet engine, a chemical plant, or a clean room, PEEK cable provides performance where standard cables might fail.

• What are the key applications of PEEK wires and cables in modern engineering?

  May 30, 2025

  In today's engineering environment with increasingly stringent performance requirements, PEEK wires and cables are being widely used as a high-performance solution in various industries that require high reliability and resistance to extreme conditions. PEEK (polyetheretherketone) has excellent thermal stability, mechanical strength and chemical resistance, and has become an indispensable key material in various industrial cable systems.   Aerospace and Defense Field PEEK cables are widely used in the aerospace field due to their light weight, high strength and stable performance in high temperature and high radiation environments. From satellites, aircraft engines to missile systems, PEEK insulated cables can ensure the stability and durability of signal transmission. Compared with traditional fluoropolymer insulation, PEEK cables have stronger dimensional stability and wear resistance, and are particularly suitable for aviation harness systems.   Medical and Life Sciences In medical technology, especially in minimally invasive surgical instruments and imaging equipment, PEEK wires and cables are favored for their good biocompatibility and resistance to high-temperature sterilization. They can withstand multiple high-pressure steam sterilizations and are suitable for high-end medical equipment such as endoscopes, surgical robots, and diagnostic probes. With the miniaturization of medical devices and the increase in data transmission speed, the demand for high-temperature resistant cables such as PEEK continues to grow.   Oil, Gas and Energy Industry PEEK cables are widely used in underground operations and submarine energy development environments, which are usually accompanied by high pressure, highly corrosive chemicals and high temperatures. PEEK's excellent chemical resistance enables it to resist erosion by corrosive media such as crude oil and drilling fluids, making it an important cable material in oil exploration and refining.     Automobile and new energy fields With the rapid development of electric vehicle technology, engineers pay more attention to the lightweight and high temperature resistance of cables. PEEK cables are widely used in power systems, battery modules and vehicle control systems due to their high heat resistance and mechanical strength. In a compact space, the thermal stability of PEEK makes it an ideal choice for high-performance cables in new energy vehicles.   Industrial Automation and Robotic Systems In the field of intelligent manufacturing and industrial robotics, cables need to withstand frequent bending, mechanical stress, and corrosion by oils or solvents. Industrial cable solutions using PEEK insulation materials not only extend service life, but also significantly reduce equipment maintenance costs. Especially in clean rooms or high-temperature environments, PEEK's low outgassing and flame retardant properties show great application advantages.   We are a professional cable manufacturer, committed to providing customers with customized high-performance cable products, covering PEEK cables, special industrial cables and high-temperature resistant cables.
