A-15 NPS Aluminum Foil / Polyester Film EMI-RFI Shielding Laminate
A-15 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 0.0015″ laminate delivers a dielectric strength of 5,000 volts, a tensile strength of 12,000 P.S.I., and elongation at break of 75%. Its unsupported construction makes it well suited for applications where a self-contained shielding layer is required rather than a pressure-sensitive tape.

A-15 NPS pairs an aluminum foil layer with a polyester film carrier in an unsupported laminate construction, giving it a self-contained EMI/RFI shielding function that does not depend on an adhesive system. Compared with the thinner A-10 NPS, A-15 NPS carries a heavier polyester film layer (0.00092″) that raises its total thickness to 0.0015″ and lifts its dielectric strength to 5,000 volts, giving it a higher voltage margin for shielding applications where slightly more insulation is required.
The laminate is supplied in silver and carries a manufacturer-rated shelf life of one year when stored at 70°F (21°C) and 50% relative humidity. A tensile strength of 12,000 P.S.I. and elongation at break of 75% allow the material to be slit, die-cut, and laminated into finished shielding assemblies without foil cracking or film delamination.
What differentiates A-15 NPS from other foil laminate grades in the A-Series line?
A-15 NPS shares the 95 dB @ 100 MHz signal attenuation common to most grades in the A-Series line but steps up to a 5,000-volt dielectric strength and 0.0015" total thickness by using a heavier polyester film layer than A-10 NPS. This gives it a higher voltage margin while remaining one of the thinner grades in the family.
Why does tensile strength matter for A-15 NPS?
As an unsupported foil/film laminate with no adhesive backing, A-15 NPS relies on its 12,000 P.S.I. tensile strength and 75% elongation at break to withstand slitting, die-cutting, and lamination without tearing the foil or delaminating the film, preserving a continuous shielding layer through converting.
What is the storage range for A-15 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-15 NPS suitable for FCC-regulated EMI/RFI shielding environments?
No — the manufacturer's TDS for A-15 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-15 NPS be specified?
Specify grade (A-15 NPS), thickness, color, compliance requirements, dimensional tolerances, and finished format.
