PEEK wire (Polyether ether ketone) is a high-performance engineering plastic known for its exceptional temperature resistance (up to 240°C), high strength, and durability. It offers outstanding mechanical properties, chemical resistance, thermal stability, electrical insulation, and a low friction coefficient, making it suitable for a wide range of demanding applications. Tianjin Ruiyuan develops and produces PEEK wires in both round and flat conductor configurations.
Key advantages of PEEK wire include:
00001. High-Temperature Performance: PEEK wire operates reliably in high-temperature environments, featuring a low thermal expansion coefficient and excellent mechanical strength. Its continuous service temperature can reach 260°C.
00002. Chemical Resistance: It demonstrates exceptional resistance to acids, alkalis, solvents, and other chemicals, making it ideal for harsh chemical environments.
00003. Superior Mechanical Properties: With high tensile strength, rigidity, and wear resistance, PEEK wire can withstand significant mechanical stress and friction.
00004. Excellent Electrical Insulation: As an outstanding insulating material, PEEK wire exhibits low dielectric constant and minimal dielectric loss.
In summary, due to its high-temperature resilience, mechanical strength, chemical resistance, and superior insulation, PEEK wire is widely used in industries such as aerospace, automotive, electronics, and medical devices.
