Composition: Ag Form: Insulated Wire Material: Silver CAS Number: 7440-22-4 Commodity: Precious Metals Purity: 99.99% Insulation: Polyurethane Insulation Thickness: 0.005mm
Polyurethane-Insulated Silver Wire merges the unmatched electrical conductivity and corrosion resistance of silver with the flexibility, abrasion resistance, and dielectric strength of polyurethane insulation. It is particularly suited for high-frequency, low-loss signal transmission in aerospace, telecommunications, and precision measurement systems. Applications include RF cables, sensitive data transmission lines, and corrosion-resistant sensor wiring. Its flexibility and resilience to wear make it valuable for equipment exposed to movement, vibration, or outdoor conditions. In research, it is used for high-frequency loss studies, insulation performance under repeated flexing, and silver corrosion resistance evaluation in mixed environments. The combination of electrical excellence and flexible insulation provides reliable performance in advanced communication and instrumentation applications.
