Its corrosion-resistant, flexible yet sturdy design ensures long-lasting protection in professional settings, with easy customization and installation options for walls, ceilings, and floors. ## Description Description WMF200 is a specialized magnetic shielding film made from an amorphous cobalt alloy, designed to shield against Low-Frequency (LF) and High-Frequency (HF) radiation. It is easily cut, allowing you to create customized shapes and sizes to fit any area, and is also highly resistant to corrosion, even when exposed to humid temperatures. The attenuation of the material remains constant at 40 dB at 1 GHz, even when under high stress. The cobalt strips makes the WMF200 very flexible, while still remaining solid so that it can keep its shape. Since these strips are so thin and thus quite sharp, the film is laminated to provide protection; it is this lamination that also prevents corrosion. Processing It can be difficult to glue the material without causing creases, and so it may be best to cover the area with solid wall coverings. When using the film on walls, ceilings and floors, we suggest that you use a highly viscous adhesive which adheres to non-absorbent substrates. First, smoothen the glue, then lay up the film, and finally apply it with a pressure roller or similar tool. The sheets should overlap, and then can be painted over if you so chose. Grounding WMF200 is electrically isolated. In order to ground the film, the strips must be screwed with a chopper disk which penetrates the plolyester. ## Features - Width: 4 inches, Length 24 inches - Attenuation HF: 40 dB at 1 GHz Weight: 265 g/m²; Material thickness: 0.1 mm; Color: Silver - Permeability: µ 4 = 25,000; µ max. = 100,000; Saturation polarization: 0.55 T - Materials: Polyester, Co69, Fe4, Mo4, Nb1, Si16, B7 - Weight: 265 g/m² ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HDL0M8S | | ASIN | B01HDL0M8S | | Best Sellers Rank | #141,338 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #29 in Radiology Aprons & Shields | | Brand | WOREMOR | | Color | Silver | | Customer Reviews | 3.9 3.9 out of 5 stars (33) | | Date First Available | June 21, 2016 | | Enclosure Material | Polyester | | Item Dimensions W x H | 4"W x 24"H | | Item Weight | 0.2 kg | | Manufacturer | Woremor | | Manufacturer | Woremor | | Mfr Part Number | WMF200 | | Mounting Type | Ceiling Mount, Wall Mount | | Number of Items | 1 | | Screen Dimensions | 4 x 24 inches | | UPC | 611138305358 611138305402 | | Unit Count | 1 Count | ## Product Details - **Brand:** WOREMOR - **Display Dimensions:** 4 x 24 inches - **Material:** Polyester - **Mounting Type:** Ceiling Mount, Wall Mount - **Product Dimensions:** 4"W x 24"H ## Images ![WMF200: Magnetic Attenuation Film (Width 4", Length 24") | For High Frequency Signal Isolation - Image 1](https://m.media-amazon.com/images/I/41YUrB0qOsL.jpg) ## Questions & Answers **Q: Will this block neodymium magnetic fields?** A: Hello, yes it will help to shield from it. I hope that this helps. **Q: I’m looking to block a magnet. Is this material attracted to magnets, and will it block the affects from a magnet?** A: The WMF200 will not help to block magnetic fields coming from a magnet as these are DC Magnetic Fields. This material only blocks magnetic fields coming from Alternating Current sources. I hope that this helps. **Q: Where can the recommended fastener "copper disk" be purchased?** A: Hello, Please note that the chopper disk is only needed when grounding the film to reduce low-frequency electrical fields. It is not needed to shield against low-frequency magnetic fields. However, it should be available at your local hardware store. Regards, EMR Shielding Solutions Inc. **Q: Does this lay perfectly flat?** A: Hello, yes this product does lay perfectly flat when laid out. I hope that this helps. ## Frequently Bought Together - Woremor WMF200: Magnetic Shielding Film for LF and HF Radiation (Width 4", Length 24") - Golden Kocoon®- E-M-F Organic Cotton Beanie with EcoShield™ Tech Bamboo Lyocell Faraday Fabric Silver Liner- Adult Size Hat in Black -5 g, BT, Smart Meters & WiFi- Cocoon Cap --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/54818546-wmf200-magnetic-attenuation-film-width-4-length-24-for-high](https://www.desertcart.jp/products/54818546-wmf200-magnetic-attenuation-film-width-4-length-24-for-high) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-26*
