Absorbing Foam
High-Loss, Broadband, Customizable, Soft & Lightweight
Guanxu® GXM-series absorbing foam is a flexible polyurethane-based microwave absorber engineered to deliver tailored electromagnetic absorption performance across a broad frequency range of 1–100 GHz. The material can be customized in shape and size according to customer requirements.
GXM features wideband high absorption, ultra-lightweight and soft texture, excellent thermal stability (operating reliably across wide temperature ranges), flame retardancy, and high cost-effectiveness. It is primarily used for EMC solutions in antennas, radars, and other electronic systems, especially ideal for weight-sensitive applications such as aerospace, drones, and portable devices.
Key Features

Carbon-based absorbing agents, extremely lightweight

Available as single-layer or multi-layer flat absorber panels

Easily fabricated into complex or custom-shaped parts

Market Applications
Commercial Communications
Industrial Electronics
Test & Measurement Equipment / Anechoic Environments
Security & Defense
Key Applications
When applied to metal surfaces, significantly reduces electromagnetic wave reflections caused by metallic objects or structures.
Provides isolation between components or antennas via insertion loss, without requiring a metal backing or support.
Used in test enclosures or small shielded chambers to minimize background reflections.
Deployed in anechoic chambers to cover columns, brackets, and fixtures, thereby reducing measurement interference and mitigating potential radar exposure risks to personnel.
