Stillpoints ERS Fabric (EMR / RFI Supression Material)
6" x 17" sheet
The ERS (EMI/RFI Suppression) material redirects, absorbs, and diffuses EMI/RFI frequencies.
The benefits of ERS for audio/video are best heard with digital circuits due to the RFI creating aspect of the circuitry itself. Benefits of ERS can also be heard with AC power lines, signal cables, loudspeakers and electronics of all types.
EMI/RFI materials have been around for a long time. Most of them are heavy and hard to apply. Many need to be grounded to be effective. None of them are as light weight or easy to deploy as ERS, where grounding is not necessary.
WHAT IS IT MADE OF?
The core of ERS is made of a blend of carbon fibres of various lengths and sizes. Using a proprietary method, these fibres are coated with metals, such as nickel. The exterior is laminated with a polyester textile on both sides to make the material easier to handle and use.
ERS may be purchased with a Pressure Sensitive Adhesive (PSA) already applied for easy and quick installation. THis PSA is repositionable within a few hours and then becomes permanent. However, saturation of the material with GOOGONE will allow for easy scraping and removal.
The edges of ERS does have exposed conductive fibres and should be handled and installed with care. The electrical resistance of ERS is .026 ohms per square yard.
The polyester fabric will insulate the core of ERS, to some degree, but can easily be penetrated with sharp edges. Caution should be exercised when used in close proximity to circuitry.
ERS is treated to accept many laminating resins such as epoxy and polyester resins.
