Signal-shielding mesh fabric made of polyester with copper and nickel plating. Transparent, flexible material that blocks or attenuates radio and electronic signals with a measured shielding performance of 70–90 dB. Key benefits Protects data privacy and reduces unauthorized wireless access by attenuating RF signals. Versatile and easy to work with: sew, fold, or integrate into garments and accessories. Lightweight, semi-transparent mesh preserves breathability and flexibility while providing shielding. Main specifications Material: Polyester + copper + nickel (conductive plated mesh) Shielding performance: 70 to 90 dB Size: 39" x 43" (100 x 108 cm). Each piece is 43" wide and 39" long. Appearance: transparent mesh suitable for lining or visible applications How it solves problems Prevents RFID skimming and unauthorized scanning when used to fully enclose wallets, passport sleeves, or card holders. Reduces exposure to ambient radio frequency or electromagnetic signals when used in curtains, blankets, or room dividers. Offers an added layer of signal protection for devices when incorporated into phone cases, laptop covers, or equipment enclosures. Compatible uses and common applications Personal security accessories: RFID wallets, passport covers, card sleeves, travel pouches. Apparel and wearables: lining for jackets, maternity wear, protective suit layers where signal blocking is required. Home and gear: curtains, blankets, bags, laptop or mainframe covers, and phone cases. Outdoor and travel items: fanny packs, gear pouches, and protective sleeves for electronics. Practical use scenarios Travel: Sew a passport sleeve from the mesh to block RFID and wireless tracking while moving through crowded transit hubs. Everyday carry: Line a wallet or card holder to prevent contactless card skimming; shielding is most effective when the item is fully enclosed. Home privacy: Install as a curtain or blanket layer to reduce RF levels in a bedroom or home office area for privacy or sensitive equipment. Installation note For maximum shielding performance, items should be completely enclosed by the fabric or combined with grounding where appropriate. Shielding effectiveness can vary with construction and coverage. This conductive polyester mesh provides a straightforward, fabric-based solution to reduce signal transmission and improve privacy in a wide range of sewn or fitted products.
