Composition: SiO₂ 81/ B₂O₃ 13/Na₂O 4
Form: Rod
Material: Borosilicate Glass
Commodity: Glasses
Type:
As-cut
Borosilicate Glass Rod offers superior thermal shock resistance and chemical durability, thanks to its low thermal expansion coefficient and high silica-boron oxide content. These rods maintain structural integrity under rapid temperature fluctuations and in corrosive environments, making them a preferred choice in both laboratory and industrial settings. Industries such as optics, analytical instrumentation, chemical processing, and precision engineering rely on these rods for their stability and machinability. Specific applications include use as stirring implements in molten glass handling, precision optical components, and high-strength feedstock for fiber drawing. Their mechanical resilience and optical clarity also support advanced research in impact resistance and failure kinetics, especially for defense and aerospace testing. The combination of precision formability, thermal stability, and chemical resistance ensures that borosilicate glass rods remain a key material in scientific innovation and specialized manufacturing.
