Surface resistance: less than 0.05 ohmMaterial: copper polyester nickelType: diamond patternRF electromagnetic fields Resistance to mold-Anti-radiation (blocking and grounding RF/EMI/EMF/LF)-Anti-electrostatic/ESD-Use in wall rendering or concrete-Replaces standard reinforcement fabric,to save costs-Very easy to cut and sew-It creates a conductive mesh,which corresponds to the idea of the Faraday cage. Brand Amradield Application for bags, curtains, tents, etc. Effective shields for basement towers, microwave signals, phones, smart meters, security systems, radars, military transmission, etc. and more. Execution of antistatic fabric, shielding of wireless meters, e-textiles, shielding curtain, radiation reduction EMI and EMI. Highly shielded conductive fabric to block RF signals such as cell phone, Bluetooth, WiFi, GPS. Jako insert in wallet or purse to protect credit cards from data theft. Nickel can cause skin allergies, this material is not intended to come into direct contact with the skin for a long time. Test : 1. Wrap the phone on four sides and wait a minute. The single will become very weak or not single. 2. Check both readings on the V/m and uW/cm2 detector to meet the low or high frequency model, sometimes the fabric needs grounding for testing. size is 1,1m*2m
