Nitto Boseki Co., Ltd Product Lineup

Nittobo’s "High-Strength Thin GFRP" is a next-generation functional material utilizing our independently developed high-strength glass fiber (GF) as a reinforcement. This high-strength GF is characterized by its superior strength and high elongation compared to conventional glass fibers. By applying this fiber, the mechanical properties of the GFRP are dramatically improved, achieving levels of strength previously unreachable with standard GF products. Developed with the core keywords of "Metal Replacement," "Weight Reduction," "High Strength," "Thin-walling," and "Insulation," this product supports the extreme thinning of components while maintaining high tensile and flexural strength. For designers seeking strength comparable to or exceeding metal in a lightweight form, this is a breakthrough solution that dramatically expands the freedom of structural design, from aerospace to everyday electronic devices.

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.

Nittobo’s "Glass Cloth Dot" is an innovative new material featuring a uniform dot-pattern coating of hot-melt resin on the surface of glass cloth. It significantly suppresses "fraying," "weave misalignment," and the generation of "glass fuzz (dust)" during cutting and processing—common challenges with conventional glass cloth. This reduces the burden on operators and contributes to maintaining a clean working environment. The most significant feature is its self-adhesive function via heating. This prevents shifting during the layering process and makes shaping to the mold easier, strongly supporting shorter working times and labor savings. The amount and spacing of the hot-melt material can be optimally adjusted according to the application. This ensures product quality stability and improved impact resistance without compromising resin impregnation. It provides the ideal solution for modern composite molding sites where productivity improvements and advanced quality are required.

Nittobo’s "Commingled Glass Cloth" is an innovative composite material created by twisting and weaving high-strength "glass fibers" with thermoplastic "organic fibers (plastic fibers)" using proprietary technology. Its greatest feature lies in "one-shot molding," which allows products to be manufactured using only heat and pressure. Since the resin is already uniformly mixed with the fibers, the material exhibits exceptional mold-following capability and impregnation. This allows for the precise molding of deep-drawn shapes and complex contours—previously difficult to achieve—in a single process. Consequently, it strongly supports a dramatic shortening of manufacturing steps, cost reduction, and labor savings. Furthermore, by leveraging the properties of thermoplastic resin, post-molding reprocessing and recycling are made easy, contributing to a reduced environmental footprint. While lightweight, it possesses high reaction force and superior impact resistance that surpass aluminum, providing a new standard for manufacturing sites where both strength and productivity are required.

Nittobo’s "GFRP with Visible Weave" is an entirely new decorative composite material developed by precisely adjusting the refractive indices of glass fibers (GF) and the matrix resin. Its greatest feature lies in achieving a sense of transparency and the natural luster of the fibers themselves—a combination previously difficult to balance in conventional FRP. The fiber bundles encapsulated within the resin strongly scatter and reflect light, causing them to appear brilliant. After molding, the glass cloth's weave pattern emerges as a three-dimensional texture, creating a deep 3D effect as if the pattern is floating deep within the resin. While enabling new design expressions that highlight the original beauty of the weave, this next-generation material also firmly maintains the electrical insulation and radio wave permeability inherent to GFRP. It adds transparency and a high-end aesthetic to products without compromising functionality.
