C-13 PS Copper Foil / Polyester Film EMI-RFI Shielding Tape
C-13 PS is a copper foil and polyester film laminate pressure-sensitive tape built from a 0.0007″ copper foil, 0.0005″ polyester film, and 0.001″ acrylic adhesive for a slim total construction of 0.0023″. It delivers signal attenuation of 105 dB @ 100 MHz, peel strength of 40 oz./inch of width, and dielectric strength of 3,900 volts. A high 30,000 P.S.I. tensile strength supports precision die-cutting into compact shielding components.

C-13 PS is a thin-gauge laminate combining a 0.0007″ copper foil with a 0.0005″ polyester film carrier and a 0.001″ acrylic pressure-sensitive adhesive, purpose-built for EMI and RFI shielding of electronic enclosures and assemblies. The copper foil supplies the conductive shielding layer while the polyester film reinforces the laminate for handling and converting, and the acrylic adhesive provides a strong, reliable bond to substrate surfaces.
The material is supplied with a 90 lb. release liner for clean die-cutting and application, in a copper finish. It carries a shelf life of one year when stored at 70°F (21°C) and 50% relative humidity. Its low 5% elongation at break and high 30,000 P.S.I. tensile strength make it well suited to tight-tolerance die-cut parts on flat or gently contoured surfaces.
What differentiates C-13 PS from other tape grades in the line?
C-13 PS is the thinnest copper-foil grade in the line at just 0.0023" total thickness, combined with an exceptionally high 30,000 P.S.I. tensile strength — well above heavier grades like C-45 PS or C-58 PS — making it the preferred choice where a low-profile, precisely die-cut shielding component is required over a highly conformable one.
Why is peel adhesion important for C-13 PS?
C-13 PS carries a 40 oz./inch of width peel rating (ASTM-D-1000), which keeps the thin foil laminate securely bonded to the mounting surface despite its low 5% elongation. Reliable adhesion is essential to prevent lifting at cut edges, which would otherwise break shielding continuity.
What is the storage range for C-13 PS?
The TDS specifies a shelf life of 1 year when stored at 70°F (21°C) and 50% relative humidity.
Is C-13 PS suitable for FCC-regulated EMI/RFI shielding environments?
No compliance standard is specified on the manufacturer's TDS for C-13 PS. Measured attenuation performance (105 dB @ 100 MHz per ASTM D4935-99) is provided, but suitability for a specific FCC-regulated application should be confirmed against the relevant project requirements.
How should C-13 PS be specified?
Specify grade (C-13 PS), thickness, color, adhesive type, liner type, compliance requirements, dimensional tolerances, and finished format.
