Pyramidal foam absorber Single /multi-layer flat foam absorber Weatherproof,multi-layer foam absorber


FTF(single layer) and FTM(multi-layer) are a series of solid, flat type foam absorbing materials made from bulk resistive polyurethane foam. It is well suited for use in shielding box, or inside of equipment that has EMI problem. The different thickness product of single and multi-layer flat absorber can be provided per customer requirement. The normal front surface color can be with/ or without blue-gray painting.

The FTF/FTM product should be installed on the metal surface to ensure the absorbing function. If necessary, the Aluminum foil can be added per customer requirement.

Maximum service temperature is -30° C ~ 90 ° C.
