Nitto Boseki Co., Ltd Product Lineup

Nittobo’s Glass Fiber Reinforced Transparent Material (developmental product) is a next-generation composite that fuses the structural strength of glass fiber with the superior light transmittance of transparent resin. Conventional FRP (Fiber Reinforced Plastics) faced the challenge of becoming opaque due to light reflecting at the interface where the refractive indices of the resin and glass fiber differ. This product achieves unprecedented levels of transparency by utilizing precision control technology to match the refractive indices of both materials to the limit, thereby suppressing interface reflection. The greatest advantage lies in simultaneously overcoming the lack of strength in transparent plastics and the brittleness/fragility of tempered glass. While being lightweight, it possesses high rigidity and "toughness" that prevents shattering upon impact, making it suitable for structural components where safety is paramount. This high-performance material resolves the design dilemma of requiring light transmission without compromising strength, expanding possibilities as a tough, lightweight alternative to glass and acrylic.

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.

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.
