MC-180 is an unsupported electrodeposited (E.D.) copper foil laminated to a polyester film carrier, engineered for electrical and electromagnetic shielding applications. Because it uses no adhesive, it is designed to be compatible with copper braids and copper conductors, allowing it to be integrated directly into cable and wire shielding constructions.
Supplied in a natural copper color with a one-year shelf life at 70°F (21°C)/50% R.H., MC-180 carries a tensile strength of 25,000 P.S.I. and breaking strength of 45 lbs./inch of width, with elongation at break greater than 5% — properties suited to the tension and flexing involved in wire and cable shielding conversion. The manufacturer’s TDS does not report dielectric strength or signal attenuation data for this grade.
What differentiates MC-180 from other foil laminate grades in the line?
MC-180 uses an electrodeposited (E.D.) copper foil rather than the rolled copper foil used in the C-series grades, and it is specifically formulated for compatibility with copper braids and copper conductors — making it the preferred choice for wire and cable shielding that must bond or interface with copper conductor systems.
Why does breaking strength matter for MC-180?
With a breaking strength of 45 lbs./inch of width and tensile strength of 25,000 P.S.I., MC-180 must withstand the mechanical tension of wire and cable shielding processes, including wrapping, braiding, and lamination, without failure; its elongation at break greater than 5% provides added margin during these converting operations.
What is the storage range for MC-180?
The manufacturer's TDS lists a shelf life of 1 year when stored at 70°F (21°C) and 50% relative humidity.
Is MC-180 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 MC-180 be specified?
Specify grade (MC-180), thickness, color, compliance requirements, dimensional tolerances, and finished format.
