Custom Cutting and Laser Micromachining
For customers requiring custom sizes or finished components rather than raw stock, Goodfellow offers precision cutting and micromachining services to drawing and specification.
| Capability | Details |
|---|---|
| Dimensional range | Min. thickness: 0.025mm Max. thickness: 0.125mm Max. width: 610mm |
| Dimensional tolerance | Linear dimensions ±1mm (<100mm) or +2/-1% (>=100mm) |
| Volume range | Prototype quantities through to several hundred-piece production runs |
| Lead time | Custom sizes: 48 hours to 1 week Complex geometries: ~2-4 weeks from confirmed drawing |
| Laser micromachining | For complex geometries requiring tight tolerances or intricate features beyond conventional machining, our polyimide film can be processed via laser micromachining through our microfabrication division, with a standard achievable target around 2 µm (tolerance +2/−1 µm) |
| Technical support | Goodfellow can review customer drawings and advise on design improvements for functionality and cost reduction. |
Key Features
Polyimide Film Metallized with Aluminum (50–80 nm) is a polyimide film in flat sheet form sharing the base chemistry of Kapton® HN, supplied with a vacuum-deposited aluminum layer on one face for applications where DuPont substrate certification is not a specification requirement:
Thicker Aluminum Coating (50–80 nm) for Improved Shielding & Opacity
The 50–80 nm aluminum coating is thicker than the 30 nm layer on Kapton® HN metallized variants, delivering improved EMI shielding effectiveness, better surface opacity, and greater resilience against atomic oxygen erosion in low Earth orbit.
Comparable Thermal Capability, Electrical Insulation & UL 94 V-0 Compliance to Kapton® HN
The polyimide substrate shares the base chemistry of Kapton® HN, offering comparable thermal capability, electrical insulation, and UL 94 V-0 compliance for applications where DuPont substrate certification is not a specification requirement.
Improved EMI Shielding Effectiveness Over 30 nm Variants
Improved EMI shielding effectiveness over 30 nm variants suits this film to reflective EMI shielding wraps and insulation laminates for wire harness protection where stronger electromagnetic attenuation is required.
Greater Resilience Against Atomic Oxygen Erosion in Low Earth Orbit
The thicker aluminum coating provides greater resilience against atomic oxygen erosion in low Earth orbit than 30 nm alternatives, extending service life of Multi-Layer Insulation blankets and reflective shielding components deployed in LEO.
Suited to Coating Thickness Comparative Research
In research, this film supports reflectance and emissivity measurement, metallization adhesion characterization, and comparative studies of coating thickness effects on aerospace polymer performance, where the 50–80 nm thickness range can be directly compared with 30 nm Kapton® HN variants.
Industrial Applications
Polyimide Film Metallized with Aluminum (50–80 nm) is used across spacecraft thermal management, EMI shielding, and research sectors where improved aluminum coating thickness is required and DuPont substrate certification is not a specification constraint:
- ✦ Multi-Layer Insulation Blankets for Spacecraft Thermal Control
- Used in Multi-Layer Insulation blankets for spacecraft thermal control, where the thicker 50–80 nm aluminum coating provides improved infrared reflectivity and greater resilience against atomic oxygen erosion compared with 30 nm alternatives.
- ✦ Reflective EMI Shielding Wraps
- Formed into reflective EMI shielding wraps, where improved EMI shielding effectiveness over 30 nm variants ensures stronger electromagnetic attenuation for spacecraft and electronics harness protection applications.
- ✦ Insulation Laminates for Wire Harness Protection
- Used as insulation laminates for wire harness protection, where greater surface opacity and improved aluminum layer robustness against atomic oxygen erosion extend service life in LEO wire harness protection applications.
- ✦ Reflectance & Emissivity Measurement Research
- Supports reflectance and emissivity measurement research, where comparable-to-Kapton®-HN polyimide properties combined with the thicker 50–80 nm aluminum coating allow direct comparison with 30 nm Kapton® HN results.
- ✦ Metallization Adhesion Characterization & Coating Thickness Comparison Studies
- Used in metallization adhesion characterization and comparative studies of coating thickness effects on aerospace polymer performance, where the 50–80 nm coating range provides an experimental variable against the 30 nm Kapton® HN baseline.
