ECCOSORB® QR-13AF or (Antimony Free) is an environmentally friendly UL-94-HF-1 rated fire retardant version of the popular ECCOSORB® LS foam. Similar in design yet stiffer in nature due to the flame-retardants used, ECCOSORB® QR-13AF will generally not dust or flake off. It is not weatherproof, but can be supplied with a special coating called CERSEAL for outdoor use or where the absorber may come in contact with fuel, lubricants, or hydraulic fluids. It can be easily cut with a knife and held in place with either a Pressure Sensitive Adhesive (PSA) or attached with a liquid based contact cement ECCOSTOCK® 13-111-NF.
ECCOSORB® QR-13AF is designed for the suppression of cavity resonances in shielded high-frequency modules and the absorption of parasitic radiation emanating from high speed electronic circuits. It can be used to line the interior of a cavity to lower its Q in RF amplifiers, cabinets containing microwave devices or computer housings requiring a high UL rated absorber. It can also be used for the isolation of antennas by insertion loss.
