MIL-STD-461G and IATF 16949 certified foam metal shielding materials — qualified for U.S. defense procurement supply chains and Tier 1 consumer electronics OEM programs. U.S. stock, 2-hour quote, $79 sample kit.
PrometheanFoam materials are engineered to meet the qualification requirements of two demanding supply chain ecosystems — U.S. defense procurement and high-volume consumer electronics OEM manufacturing.
Our multi-layer laminate and copper foam EMI materials satisfy MIL-STD-461G requirements for electromagnetic interference control in defense subsystems. ITAR registration and DFARS compliance enable direct contracting with DoD agencies and prime defense contractors — no foreign sourcing risk.
PrometheanFoam's precision-cut conductive foam and copper foam are engineered to meet the dimensional, outgassing, and electromagnetic performance standards required by Tier 1 consumer electronics OEM supply chains — including mobile devices, laptops, wearables, and wireless accessories. ±0.2 mm die-cut tolerance. ISO 9001:2015 certified. PPAP documentation available for Tier 1 qualification programs.
Four material grades covering 10 MHz to 40 GHz — from consumer electronics to classified defense programs. All tested per ASTM D4935 and MIL-STD-461.
