Absorbing Particles-Absorbing material-Nanjing Guanxu New Materials Technology Co., Ltd.

Absorbing Particles

High-Loss, Thermoplastic, Easy to Process
Guanxu® GXS thermoplastic microwave-absorbing plastic pellets are engineered to enable structural components—such as antenna radomes, cable sheaths, and microwave absorber loads—with built-in electromagnetic wave absorption capabilities. By combining Guanxu’s proprietary microwave-absorbing agents with organic polymer matrices, these magnetoplastic granules can be processed via injection molding, extrusion, or compression molding to produce complex, functional parts tailored to customer-specific electromagnetic and structural requirements.

Key Features

High electromagnetic loss (high Power Loss)

Enables one-step molding of complex geometries, reducing assembly steps and part count

Ideal for intermediate structural components, lowering overall system cost

Excellent environmental stability and long service life

Glass-fiber reinforced options available for superior mechanical strength

Market Applications

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

Key Applications

Reduce electromagnetic reflection from device structures and suppress cavity resonances inside electronic enclosures
Typically installed inside electronic devices or near antennas to absorb spurious signals, surface waves, and unwanted harmonics—without affecting other device functionalities
Typical use case: Automotive radar absorbing radomes and brackets, which enhance radar performance and reliability by mitigating electromagnetic interference (EMI)
Serve as microwave terminations/loads in waveguides and microwave components
