C-13 NPS Copper Foil / Polyester Film EMI-RFI Shielding Laminate
Short Description
C-13 NPS is a copper foil and polyester film laminate constructed without adhesive or liner, at a total thickness of 0.0013″. It provides signal attenuation of 105dB @ 100 MHz and a dielectric strength of 3,900 volts, with tensile strength of 30,000 P.S.I. and elongation at break of 5%. Its unsupported construction makes it well suited for applications where a self-contained shielding layer is required rather than a pressure-sensitive tape.

C-13 NPS is an unsupported copper foil laminated to a polyester film carrier, engineered specifically for EMI and RFI shielding of electronic components. Because it carries no adhesive or liner, it functions as a self-contained shielding layer that can be incorporated directly into composite shielding assemblies, cable constructions, or enclosure linings, rather than being applied as a pressure-sensitive shielding tape.
The laminate is supplied in a copper color and carries a one-year shelf life when stored at 70°F (21°C) and 50% relative humidity. Its combination of thin gauge (0.0013″ total thickness) and high tensile strength (30,000 P.S.I.) allows it to be slit, die-cut, and laminated into finished parts without tearing, while its 105dB signal attenuation at 100 MHz and 3,900-volt dielectric strength support demanding shielding requirements.
What differentiates C-13 NPS from other foil laminate grades in the line?
At just 0.0013" total thickness, C-13 NPS is among the thinnest grades in the copper foil/polyester film shielding line, yet it still delivers 105dB of signal attenuation at 100 MHz and 30,000 P.S.I. tensile strength — allowing it to be used where minimal added thickness is required without sacrificing shielding performance or converting durability.
Why does tensile strength matter for C-13 NPS?
Because C-13 NPS is supplied without adhesive or liner, its tensile strength (30,000 P.S.I.) is what allows it to withstand the tension of slitting, die-cutting, and laminating operations during conversion; at only 5% elongation at break, the material must be handled with appropriate web tension to avoid tearing during processing.
What is the storage range for C-13 NPS?
The manufacturer's TDS lists a shelf life of 1 year when stored at 70°F (21°C) and 50% relative humidity.
Is C-13 NPS suitable for FCC-regulated EMI/RFI shielding environments?
No compliance standard is specified on the manufacturer's TDS for this material; specifiers requiring FCC or other regulatory certification should confirm suitability independently.
How should C-13 NPS be specified?
Specify grade (C-13 NPS), thickness, color, compliance requirements, dimensional tolerances, and finished format.
