Both SW1000 & SW2000-series absorbers, using silicone rubber as the substrate and mixed with magnetic filler, are specially designed for the reflection loss of high incident plane waves, and are suitable for the frequency range of 2-40GHz. The substrate material features high temperature resistance, oil resistance and flame retardant. The magnetic filler has excellent wave absorption performance when the incident angle is greater than 65°. The product reflectivity measurement refers to GJB2038A-2011.
The SW-series is used to “eliminate” the electromagnetic noise in the closed cavity structure, reduce the “Standing Wave” generated by the microwave resonance in the casing and the “Q” value in the cavity. It can also effectively isolate the bottom plate and the antenna, improve antenna gain. The SW series offers a solution for electromagnetic shielding in the 2-40GHz range by combining with other EMI materials.
Our RF Absorber Silicone Rubber is a composite material featuring a silicone elastomer matrix loaded with specialized magnetic or conductive particles. This combination allows the material to function as both a high-frequency absorber and an environmental seal, capable of withstanding temperatures ranging from -55°C to +200°C. It is particularly effective at suppressing cavity resonances and surface currents in radar and telecommunications equipment. To ensure long-term reliability in the field, these materials are tested to meet the ASTM D412 standards for vulcanized rubber and thermoplastic elastomers, ensuring consistent tensile strength and elongation. This ensures that every RF Absorber Silicone Rubber part maintains its physical integrity and shielding effectiveness even under extreme thermal and mechanical stress.
