Introduction to Lossy Rigid Foam
Hexcel's Lossy Rigid Foam, also known as Rigid LS, offers an excellent solution for the suppression of electromagnetic energy. This RF absorber is designed to be easily cut, wrapped, and applied, making it versatile for various applications. The foam consists of a low-density, high-loss, carbon-impregnated open-cell structure, available in different thicknesses and carbon loadings to cater to specific frequency absorption needs. With a halogen-free composition and compliance with RoHS and REACH standards, Hexcel's Lossy Rigid Foam ensures both efficiency and environmental safety.
Product Overview and Features
The LS series of foam is characterized by its open-cell structure with carbon loadings, providing a lightweight and customizable solution for high or low loss requirements. This product is particularly effective for far-field applications and is commonly used in multi-layer configurations to optimize performance. By utilizing various carbon loadings in layered form, the Lossy Rigid Foam offers broadband absorption from 500MHz to 40GHz. Its ability to reduce multiple reflections in cavities enhances overall performance, making it a suitable choice for applications requiring precision.
Effectiveness and Applications
The success of the LS material as an RF absorber stems from its open-cell foam construction, enabling it to absorb electromagnetic interference efficiently. Its cost-effectiveness and ease of handling further add to its appeal. The foam can be machined for outdoor use and exhibits increased loss at higher frequencies due to its foam thickness and shorter wavelength interaction. Common applications of Hexcel's Lossy Rigid Foam include crosstalk reduction, antenna shrouding, RCS measurements, and components for anechoic chambers, with excellent performance in a broad range of scenarios.
Additional Features and Customization Options
Hexcel's Lossy Rigid Foam offers the flexibility to include elastomer coatings for resistance against various substances like jet fuel, hydraulic fuel, gasoline, and water, expanding its usability in different environments. The product can be machined to customer specifications, allowing for precise angles and cuts to meet specific project requirements. Whether used in a standalone capacity or as part of a multilayer system, the Lossy Rigid Foam provides reliable electromagnetic interference control with a focus on performance and user convenience.
