Automotive Wiring Harness Protection — Wire Wrapping Film Improves Insulation Reliability

Project BackgroundA new energy vehicle component supplier, during vehicle wiring harness assembly, needs to provide insulation protection and fixation for high-voltage wiring harnesses and signal wiring harnesses. The material is required to have excellent heat resistance, flame retardancy, and waterproof performance.

Core ChallengesNew energy vehicle wiring harnesses operate in high-temperature and high-vibration environments. Traditional PVC tape is prone to aging and falling off under long-term high temperature, has insufficient waterproof performance, and poses a short-circuit risk. At the same time, wiring harness routing is complex, requiring the material to have good flexibility and self-adhesion.

SolutionFORWA PTFE Wire Wrapping Film is used. This product is a high-performance electrical insulation and wiring harness protection material with excellent insulation, high-temperature resistance, flame retardancy, and self-fusing properties. After stretching, it fits tightly around the wiring harness, forming a sealed protective layer that effectively provides waterproof, moisture-proof, and wear-resistant protection.

Application Results | The reliability of wiring harness insulation protection is significantly improved. After 1,000 hours of 85°C/85%RH high-temperature and high-humidity aging testing, performance shows no degradation. This material has been mass-applied to multiple new energy vehicle platforms.
