The expansion of AI infrastructure is driving demand for platinum

A unique feature of platinum is that it is exceptionally resistant to heat and wear. In fibreglass production, platinum-rhodium bushings are used to draw molten glass into fine fibres at extremely high temperatures.

Fibreglass produced this way is used to produce electrical-grade glass (E-glass) yarn which can be woven to create different types of E-glass fabric.
Known for its high strength and excellent electrical insulation, E-glass fabric is an important component in a printed circuit board (PCB). 

AI servers and data centre equipment cannot function without PCBs and, as AI workload increases, PCB designs are evolving to support higher speeds and frequencies, especially through the integration of low-Dk (low loss) materials. 
Platinum glass demand is forecast to increase by 83% year-on-year to 377 koz in 2026. Growth will be driven by renewed expansion in fibreglass applications, supported by the return of capacity additions and stronger demand from higher value end-uses, including those linked to AI.
