Unbreakable, strong, and easy to handle resin-sealed glass cloth.
Suppressing fraying and enhancing rigidity. A special end-stopping treatment dramatically improves workability, tensile strength, and impact resistance, contributing to the high functionality of automotive components.
Nitto Bō's "Resin Sealed Glass Cloth" is a mass-production compatible cloth that fundamentally solves the issues of fraying and lack of rigidity during processing by applying a special resin sealing treatment to glass cloth. Its greatest feature lies in its excellent processability and high ease of handling. It minimizes misalignment during cutting and fraying of the weave to the utmost limit, achieving a texture with moderate stiffness. It also supports the Roll to Roll process that underpins continuous production, thereby enhancing operational efficiency in processing environments. In terms of functionality, the resin sealing provides higher tensile strength, higher elasticity, and impact resistance compared to conventional treated cloths (such as silane-treated cloths). Additionally, it retains the inherent excellent heat resistance and electrical insulation properties of glass fibers. As a thin reinforcement material that demands increased rigidity and strength, it offers optimal solutions for the modern mobility sector, ranging from structural components in automobiles that require stringent safety standards and durability to components around onboard batteries.
