Significant Improvement in Radio Wave Permeability for Communication Components: Low Dielectric Constant (Low-Dk) Glass Cloth
Making radio wave pathways smoother. Nittobo’s low-Dk glass cloth revolutionizes the permeability of increasingly sophisticated communication and radar equipment.
Nittobo's "Low-Dk Glass Cloth" is a product made from specialized glass fibers with a lower dielectric constant (Dk) and dissipation factor (Df) compared to conventional E-glass. In modern communication and radar technologies, the radio wave permeability of components is crucial. By using this product as a reinforcing material for FRP (Fiber Reinforced Plastics), it is possible to significantly enhance the radio wave permeability of communication-related components, such as radomes.A key feature of this material is its ability to maintain processability and mechanical properties nearly identical to those of standard E-glass cloth, while providing superior electrical characteristics. It also shows excellent compatibility with various resins, including epoxy and cyanate ester resins, allowing for integration using existing molding processes. This high-performance material offers a new solution for demanding environments—such as next-generation high-speed communications and the aerospace industry—where both precise signal transmission and high structural strength are required.
