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.
  • Features:
    • Excellent Broadband Performance
    • -10° ~70° C Service Temperature • Fire Retardant (ISO 11925-2、UL 94 HBF、NRL8093 Test1、2、3)

    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 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.

    Standard sizes of HR-HPM are listed in Table 1, ranging from a 1 inch to 72 inch height. In addition to simply supplying a bill of materials,
    Microwave designs and installs complete anechoic chambers. Chambers can be designed to meet your specifications, and an entire kit
    of materials is supplied, including factory pre-cuts of special fitting parts. We can install all materials or supply technical support
    to help you complete your own installation.
