Absorbent sponge
HR-HPM Absorber is a series of high performance broadbanded RF absorbers made
from specially treated low density polyurethane foam. The product is flexible and tolerant
of physicalabuse. Using a steep pyramid design which provides an impedance gradient,
HR-HPM Absorber provides premium performance in anechoic chambers at both normal
and off-normal incidence angles. These products meet of the fire retardancy requirements
of UL 94 horizontal burning foamed material test.

Introduction :
HRRF Series absorbing material is HANRUIN Technology Co., Ltd. R & D flat absorbing
foam, flame proof , soft texture of ultra-wideband electromagnetic absorber.
TYPICAL PROPERTIES
Typical weights, dimensions, and reflectivities of the various grades of HR-HPM Absorber are given in the tables on the reverse side.
Typically, HR-HPM Absorbers can handle up to 1.0 W/in2 (2 kW/m2) of RF energy in a temperature controlled room,
but this is dependent upon frequency and application.
The product is black throughout, and generally is sprayed with a light blue surface coating, both for cleanliness and to provide better
light reflection inside a chamber. The absorber can be left unpainted if requested.
