According to GlobalData’s company profile on Nitto Boseki, Interlaced yarn fabrics was a key innovation area identified from patents. Nitto Boseki's grant share as of July 2024 was 47%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent US12041727B2 introduces a novel surface-treated glass cloth characterized by a specific surface-treated layer. This layer incorporates a silane coupling agent and features a precise composition of carbon, which is maintained between 0.030% to 0.060% by mass. Additionally, the surface of the adhering component within this layer has an arithmetic average height ranging from 1.0 to 3.0 nanometers. Notably, the patent specifies that the product of the carbon amount and the average height of the surface must fall between 0.060 and 0.100, with a more refined range of 0.086 to 0.093 outlined in a dependent claim.
Further applications of this surface-treated glass cloth are also covered in the patent. It includes the formulation of a prepreg that utilizes the glass cloth, as well as its integration into printed wiring boards. The inclusion of silane coupling agents, particularly those with methacryloyl or acryloyl groups, enhances the material properties of the glass cloth, making it suitable for various industrial applications. This innovation aims to improve the performance and durability of products that incorporate the treated glass cloth, thereby addressing specific needs in the manufacturing and electronics sectors.
