Conductive metalized fabrics






            Conductive metalized fabrics are structures made from polyamide synthetic fibers coated in metal conductive
            materials (copper, nickel, silver).These metalized fabrics secured to silicone bases or various foams allow to
            produce shielding seals for such applications as information technology, mobile radio, cellular telephony and
            other electronic instruments.                                                                          4
