A-10 NPS Aluminum Foil / Polyester Film EMI-RFI Shielding Laminate
A-10 NPS is an aluminum foil and polyester film laminate engineered for EMI and RFI shielding, providing signal attenuation of 95 dB at 100 MHz. Supplied without adhesive or liner, the 0.001″ laminate delivers a dielectric strength of 3,900 volts, a tensile strength of 12,000 p.s.i., and elongation at break of 70%. Its unsupported construction makes it well suited for applications where a self-contained shielding layer is required rather than a pressure-sensitive tape.

A-10 NPS is an unsupported laminate combining a thin aluminum foil layer with a polyester film carrier, forming a self-contained EMI/RFI shielding material that performs its shielding function without an adhesive system. At a total thickness of 0.001″, it is the lightest-gauge option in the A-Series foil/polyester laminate line, making it a practical fit where a low-profile shielding layer is needed within an enclosure, cable assembly, or laminated composite structure.
The laminate is finished in silver, consistent with its aluminum foil face, and is rated by the manufacturer for a one-year shelf life when stored at 70°F (21°C) and 50% relative humidity. Its 12,000 P.S.I. tensile strength and 70% elongation at break give it enough mechanical integrity to be slit, die-cut, and laminated into finished assemblies without foil cracking or film delamination during normal converting operations.
What differentiates A-10 NPS from other foil laminate grades in the A-Series line?
A-10 NPS is the thinnest grade in the A-Series aluminum foil/polyester film line, at a total thickness of 0.001". Its 95 dB @ 100 MHz signal attenuation matches the standard rating shared across most grades in the family, but its lower dielectric strength (3,900 volts) and lighter overall gauge reflect its role as the lowest-mass option — suited to applications where minimizing thickness takes priority over higher voltage margin.
Why does tensile strength matter for A-10 NPS?
Because A-10 NPS is an unsupported laminate with no adhesive backing or carrier tape, its 12,000 P.S.I. tensile strength is what allows it to be slit, die-cut, and laminated into finished assemblies without tearing the foil or delaminating the film. Combined with its 70% elongation at break, this mechanical strength keeps the shielding layer continuous through converting operations.
What is the storage range for A-10 NPS?
The manufacturer's TDS rates shelf life at 1 year when stored at 70°F (21°C) and 50% relative humidity. No separate operating temperature range is specified on the TDS.
Is A-10 NPS suitable for FCC-regulated EMI/RFI shielding environments?
No — the manufacturer's TDS for A-10 NPS does not state an FCC or any other compliance standard, so suitability for FCC-regulated programs would need to be independently verified.
How should A-10 NPS be specified?
Specify grade (A-10 NPS), thickness, color, compliance requirements, dimensional tolerances, and finished format.
