Polyimide Platinum Insulated Wire

Formula: Pt
Form: Insulated Wire
Material: Platinum
CAS Number: 7440-06-4
Commodity: Precious Metals
Purity: 99.99%
Insulation: Polyimide
Polyimide Platinum Insulated Wire is designed for high-precision applications requiring thermal stability and reliable electrical performance. The polyimide insulation withstands temperatures up to 250°C, making it suitable for aerospace, automotive, and industrial high-temperature environments. The platinum core ensures consistent electrical conductivity, making it ideal for sensors, actuators, and external biomedical research applications. Its abrasion resistance and chemical stability enhance durability in scientific instrumentation and advanced electronics. While polyimide is robust, fluoropolymer-insulated stranded wires are preferred for applications requiring continuous flexing or extreme RF performance.
