WM-STU50 EMF Protection Fabric

*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.

Properties

WM- STU50 is a semi-transparent strong silvered knit fabric for the protection against high-frequency (HF) and low-frequency radiation (LF). Typical application as net curtain, room divider in laboratories, medical practices, etc. and due to the highest washability it's perfect for bed canopies.

Special features: 1) WM- STU50 is very stable and don't loose its screening attenuation with washing or movement. 2) This fabric is hard to sew accurately, because it‘s stretchy and pulls out of place easily when you try to sew \ it. Please note that customized curtains are difficult to sew dimensionally stable!

• High transparency and very high screening attenuation
• Allows (groundable) to shield LF electric fields
• Textile similar characteristics: Washable, easy to process. Exception: Do not iron.
• Quality grade: Very high

Silver products

• Silver products discolor with time and often already have discolorations right from the start. If you don’t want to accept discolorations, please choose Swiss-Shield® fabrics.
• Silver fabrics have a limited durability, depending on the frequency of movement.
• Our silver fabrics do not contain any nano silver, but a thick metallic silver coating.
