According to GlobalData’s company profile on Nippon Sheet Glass, Vacuum insulated glazing was a key innovation area identified from patents. Nippon Sheet Glass‘s grant share as of June 2024 was 38%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent US12043566B2 outlines a novel glass fiber characterized by a ß-OH value ranging from 0.02 mm-1 to less than 0.55 mm-1. The claims detail specific compositional ranges for various oxides, including SiO2, Al2O3, B2O3, MgO, CaO, Na2O, and K2O, with SiO2 content specified between 45% to 73% by mass. Additional claims refine these ranges further, indicating optimal compositions for enhanced properties, such as a SiO2 content of 55% to 60% and a maximum diameter of 15 µm. The glass fiber is also noted to be substantially free of arsenic (As) and antimony (Sb), with a controlled sulfur trioxide (SO3) content between 0 to 75 ppm.
The patent further describes applications of the glass fiber, including its use in rubber-reinforcing cords and non-woven glass fiber fabrics. The production method involves creating a glass melt from raw materials that include a sulfuric acid salt, which can be derived from alkali or alkaline-earth metals. The claims emphasize the potential for both long and short glass fibers, with specific attributes aimed at improving performance in rubber products. Overall, the patent presents a comprehensive approach to developing glass fibers with tailored properties for industrial applications.
