Kapton® 200RS100 is DuPont's resistive-static polyimide film — a 0.05mm or 0.06mm thick Kapton® substrate coated on one side with a thin, controlled-conductivity carbon layer that provides a stable, defined surface resistivity for electrostatic discharge (ESD) management and electromagnetic interference (EMI) shielding. Where standard Kapton® HN is a pure electrical insulator, the 200RS100 grade allows controlled dissipation of electrostatic charge, low-current signal grounding, and surface-level EMI absorption — all while retaining the extreme-temperature stability, dielectric integrity of the base polyimide, and UL 94 V-0 flame resistance of the full Kapton® family. It is specified in aerospace electronics, satellite thermal management, EV battery systems, and ESD-controlled assembly environments.

Key Features
Kapton® 200RS100 is DuPont's controlled-resistivity polyimide film, adding reliable ESD dissipation and EMI management capability to the proven thermal, mechanical, and chemical performance of the Kapton® polyimide platform:
Controlled Surface Resistivity for ESD Dissipation
The carbon-based conductive coating on Kapton® 200RS100 provides a controlled, stable surface resistivity that dissipates electrostatic charge at a rate that protects ESD-sensitive components from damage while avoiding the field disturbances caused by fully conductive shielding. This dissipative characteristic is stable across the film's operating temperature range and is not degraded by humidity, solvent cleaning, or repeated thermal cycling.
EMI Shielding and Low-Current Signal Grounding
The carbon coating enables surface-level electromagnetic interference absorption and provides a low-resistance path for low-current signal grounding in shielded flex circuits, sensor enclosures, and spacecraft electronics. The resistive-static surface can be integrated into multilayer flex circuit stacks as a distributed ground plane without the weight penalty of metallic foil shielding layers.
Full Kapton® Thermal Range (−269 °C to +200 °C operational)
Kapton® 200RS100 maintains dimensional integrity and functional surface resistivity across the temperature range from deep cryogenic (−269 °C) to continuous service at elevated temperatures. This qualifies it for satellite thermal management films, space instrument electronics, and cryogenic sensor assemblies where ESD protection must be maintained across the full operational temperature range of the platform.
Polyimide Base Dielectric Integrity Preserved
The carbon-based resistive coating is applied only to the surface of a standard Kapton® polyimide substrate, preserving the bulk dielectric strength (>100 kV/mm), volume resistivity (10¹⁸ Ω·cm), and low dissipation factor (0.0018 at 1 kHz) of the base film. 200RS100 therefore functions simultaneously as an ESD-dissipative surface treatment and a high-performance dielectric insulating film — a combination unavailable in metallic or conductive films.
Dimensional Stability and Low Outgassing for Aerospace & Vacuum Use
The dimensional stability, low moisture uptake, and low outgassing characteristics of the Kapton® polyimide substrate are retained in Kapton® 200RS100, making it compatible with the NASA and ESA outgassing requirements for spacecraft materials. These properties allow it to serve as a thermally stable, ESD-managed insulating film in satellite electronics, vacuum instrument chambers, and space thermal blanket assemblies.
UL 94 V-0 Flame Rating and Mechanical Resilience
Kapton® 200RS100 carries a UL 94 V-0 flame classification and combines a tensile strength of 70–150 MPa with adequate elongation for die-cutting, laser machining, and assembly handling. Its flame resistance and mechanical toughness make it suitable for use in EV battery module insulation, motor control electronics, and aerospace wiring systems where ESD management and fire safety requirements must be simultaneously satisfied.
Industrial Applications
Kapton® 200RS100 is specified wherever polyimide's thermal stability and dielectric performance must be combined with controlled ESD dissipation or surface EMI management:
✦ Aerospace Electronics & Satellite Systems
Applied as an ESD-dissipative insulating film in satellite electronics enclosures, solar array interconnect insulation, and thermal control blanket assemblies, where triboelectric charging in the space plasma environment must be safely dissipated to prevent electrostatic discharge events that can damage or destroy sensitive electronics. The film's low outgassing and cryogenic stability are essential for long-duration space platform qualification.
✦ ESD-Controlled Electronics Manufacturing
Used as a die-cut ESD-dissipative liner, component tray insert, and packaging film in the manufacture of ESD-sensitive semiconductors, MEMS devices, and precision sensor modules. Kapton® 200RS100 provides a thermally stable, chemically resistant, ESD-safe surface for component handling in cleanroom and controlled-environment assembly areas.
✦ Flexible PCB Shielding & Signal Grounding
Incorporated into multilayer flexible and rigid-flex PCB stacks as a distributed ESD-dissipative layer and low-impedance signal return path, replacing metallic ground planes in weight- and space-constrained flex circuit applications. The resistive surface dissipates charge without the broadband signal reflections that arise from fully conductive metallic layers in high-frequency interconnects.
✦ Electric Vehicle Battery Modules
Used as an ESD-managed insulating barrier and structural support film in EV battery cell assemblies, where electrostatic discharge during manufacture and service can initiate thermal runaway in lithium-ion cells. Kapton® 200RS100 provides the combination of ESD dissipation, electrical isolation, flame resistance, and mechanical durability required by automotive battery safety standards.
✦ High-Density Interconnect Prototyping
Specified by research and development teams prototyping high-density interconnects, flexible antennas, and thermal management stacks, where its ESD-safe surface prevents charge accumulation on fine-pitch conductor patterns during handling and assembly. Its compatibility with standard PCB processing chemicals and laser ablation tools supports rapid prototyping workflows.
Applied as an ESD-dissipative film on the interior surfaces of vacuum chambers and cryostat assemblies, where triboelectric charging on insulating surfaces can disturb sensitive electrostatic or electromagnetic measurements. Kapton® 200RS100's low outgassing, cryogenic stability, and controlled surface resistivity allow it to function as a charge-dissipating liner without contaminating ultra-high vacuum environments.
✦ Medical Device Electronics & Diagnostic Sensors
Used in the assembly of ESD-sensitive medical electronic modules including implantable pulse generators, hearing device electronics, and wearable diagnostic sensor platforms, where polyimide's biocompatible chemistry and the film's ESD-protective surface combine to meet both component protection and biocompatibility requirements in body-contact and implanted device applications.
