EVOLUTION™ from Swiss-Shield® is a semi-transparent Trevira® fabric for the shielding of high-frequency electromagnetic fields (HF). Typical application as curtain. Not electrically conductive. Crease resistant Trevira®-polyester Textile characteristics: Washable, easy to iron and process Quality grade: Very high *Note: To purchase a custom length of fabric, place an order for multiple quantities of the 1ft option. The amount ordered will be cut as a single piece unless specified otherwise. Order quantity: This product is cut off according to your specifications, a return or revocation are not possible. Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation". Grounding: Not electrically conductive. No shielding of electric fields (LF), these must be reduced by additional procedures. We recommend the shielding with NSF34, NCV95 or the decoupling with a demand switch. Fabric care: Washing at gentle cycle 30°C | Ironing without steam at degree 1 | Drying at low temperature | No bleaching | No chemical dry-cleaning | For allergy sufferers: Every new fabric smells, wash before its first usage! Application: Curtain, Window, Canopy Field type: HF (High frequency electromagnetic fields) Ecology: Very high Color: White Technical data Width: 8.2 ft Length: Available by the foot Attenuation: 30 dB, two-layer 43 dB Color: White Raw materials: 91 % polyester (Trevira), 8.5 % copper, 0.5 % silver Weight: 80 g/m² Dimension stability: +/- 1 % Report screening attenuation
