What is Cascell® HF
Cascell® HF is a low dielectric foam core material specifically designed for antenna applications. It offers extremely low dielectric constants and favorable transmission properties, making it suitable for use in antennas. Additionally, Cascell® HF can be utilized as a structural core material for radomes and mammography plates.
Key points regarding Cascell® HF
Antenna applications: Cascell® HF is primarily developed for use in antennas. Its extremely low dielectric constants contribute to reduced signal loss and improved transmission properties. These characteristics are crucial in antenna design, where minimizing signal attenuation is essential for efficient signal reception and transmission.
Low dielectric constants: Dielectric constant, also known as relative permittivity, is a measure of a material's ability to store electrical energy in an electric field. Cascell® HF exhibits exceptionally low dielectric constants, which means it has a minimal impact on electromagnetic waves passing through it. This low dielectric property is desirable in antenna applications to ensure accurate signal propagation.
Transmission properties: Cascell® HF is engineered to have favorable transmission properties, meaning it allows for efficient transmission of electromagnetic waves. This property is important in antenna design, as it helps maintain the integrity of the transmitted signal and ensures optimal antenna performance.
Structural core for radomes: In addition to antenna applications, Cascell® HF can be utilized as a structural core material for radomes. Radomes are protective coverings for antennas that need to maintain their performance while providing protection from external environmental factors. Cascell® HF's low dielectric properties and structural strength make it suitable for use in radomes, enabling both protection and signal transparency.
Mammography plates: Cascell® HF can also be used as a structural core material for mammography plates. Mammography plates are imaging devices used for breast examinations. Cascell® HF's properties, such as low dielectric constants and structural stability, make it suitable for use in mammography plates, potentially contributing to improved imaging quality and accuracy.
Features of Cascell® HF
Fine closed-cell structure: Cascell® HF foam
possesses an extremely fine closed-cell structure. This characteristic indicates that the individual cells within the foam are tightly sealed, preventing the absorption of resin. As a result, the foam has minimal resin uptake during manufacturing processes.
Compatibility with metallic facing materials: The absence of corrosive effects in Cascell® HF foam ensures compatibility with metallic facing materials. This means that when using metallic facings in conjunction with Cascell® HF foam, there are no adverse chemical reactions or degradation of the metal, promoting problem-free integration and compatibility.
Processing capabilities: Cascell® HF foam is suitable for various processing methods, including hand lay-up, prepreg processing, and vacuum infusion. Hand lay-up involves manually placing layers of composite materials in a mold, while prepreg processing utilizes pre-impregnated composite materials. Vacuum infusion is a technique where resin is drawn into a mold using vacuum pressure. Cascell® HF foam can withstand temperatures up to 130°C and pressures up to 0.3 MPa during these processing methods.
