DuPont™ Kapton® 200RS100 PI Film

DuPont™ Kapton® 200RS100 PI Film is used in aerospace electronics, satellite thermal insulation, and flexible printed circuits requiring stable surface resistivity. Its carbon-based conductive coating enables reliable EMI shielding and low-current signal grounding in sensor integration. The film maintains dimensional integrity under thermal cycling from –269°C to +260°C, making it suitable for vacuum environments and space instrumentation. Researchers in laboratory environments use it for prototyping high-density interconnects, antennas, and thermal management stacks when combined with heat-spreading materials in advanced electronics and materials science applications. Additionally, Kapton® 200RS100 is employed in electric vehicle battery modules as a durable insulation barrier and structural support layer, where its flame resistance, mechanical resilience, and compact profile contribute to safer power system designs under elevated temperature and voltage conditions.
