Absorber Sheets

High-Loss, Broadband, Customizable, Soft & Ultra-Thin
Guanxu® GXR-series absorber sheets are thin, flexible, magnetic silicone rubber-based microwave absorbing materials, engineered using proprietary microwave-absorbing fillers and silicone resin. They effectively absorb electromagnetic waves across a broad frequency range of 300 MHz to 100 GHz, making them suitable for demanding applications such as aerospace—thanks to their low outgassing properties, high-altitude compatibility, and excellent high-temperature resistance.

Key Features

Ultra-broadband performance: 300 MHz – 100 GHz

High-loss, non-conductive silicone rubber sheet

Flame retardant with excellent thermal stability

Flexible, lightweight, ultra-thin, easy to cut, process, and install

Market Applications

Commercial Communications: Antennas, optical modules, routers
Millimeter-Wave Applications: 5G communications, millimeter-wave radar
Industrial Electronics: Automotive electronics, drones, etc.
Instrumentation & Measurement: Power amplifiers, filters, test systems
Security & Defense: Radar systems, etc.

Key Applications

Reduce Free-Space Wave Reflection: When applied to metal surfaces, absorbing materials significantly minimize electromagnetic wave reflections caused by metallic objects or structures.
Suppress Cavity Resonance: When adhered inside conductive enclosures, absorbers effectively dampen higher-order harmonic resonances, ensuring stable circuit operation.
Attenuate Surface Traveling Waves: Absorbers efficiently absorb creeping waves propagating along transmission lines (or equivalent structures) and conductive surfaces.
Electromagnetic Field Isolation: Leveraging their high permeability and permittivity, absorbers draw electromagnetic energy into the material, thereby enhancing electromagnetic isolation for sensitive components.
