Brisbane, Queensland, Australia--(ACN Newswire - December 11, 2024) - Graphene manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to provide a business update on the commercialisation progress of THERMAL-XR® Powered by GMG Graphene.
CUSTOMER ENGAGEMENT UPDATE
GMG continues to make progress in testing with companies in multiple industries for the use of THERMAL-XR® in their products, including on heat sinks for electronics. Figure 1 shows an aluminium heat sink that is commonly used in electronics for removing heat from printed circuit boards, electrical circuits and processing silicon chips, and that has been coated with THERMAL-XR® .

HEAT SINK MINIATURISATION:
Third-party verified modelling demonstrates that applying THERMAL-XR® to a heat sink could reduce its size by up to 39%, while maintaining equivalent thermal performance, offering the potential for weight and material cost savings. Figure 2 shows that the maximum temperature reached by a heat sink coated with THERMAL-XR® is 62 degrees centigrade, 23% lower than the maximum temperature of 80 degrees Celsius reached by a heat sink of equal size that has not been coated with THERMAL-XR®. Figure 3 shows that a heat sink coated with THERMAL-XR® that is 39% smaller in terms of width achieves the same performance as a heat sink that has not been coated with THERMAL-XR®.

Global Printed Circuit Board (PCB) production is projected[1] to reach 530 million square meters annually by the year 2030, or about 5.3 trillion printed circuit boards. As PCB density increases, higher current loads lead to more heat, with 5.2 billion units expected to require heat sinks for cooling. THERMAL-XR® coated on the heat sinks, enhances the heat sink efficiency, enabling smaller heat sinks and more compact PCB assemblies. The total amount of THERMAL-XR® that could be used for this application to improve performance is 26.5 million litres per annum by 2030, assuming 0.1% will use the coating.
GMG's Managing Director and CEO, Craig Nicol, commented: "Heat sinks are a critical component of modern electronics, but they come with various challenges, especially as devices become smaller, faster, and more powerful. GMG's THERMAL-XR® offers a potential solution in heat sink miniaturization, enabling up to 39% size reduction while maintaining thermal performance. This has the potential to not only cut material costs but also unlock new opportunities for compact and efficient electronics designs, addressing the rising thermal management demands of the global printed circuit board market."
About THERMAL-XR® powered by GMG Graphene:
THERMAL-XR® COATING SYSTEM is a unique method of improving the thermal heat transfer of heat exchange surfaces. The process coats and protects heat exchange surfaces while increasing the heat transfer rate by leveraging the physics of GMG Graphene, resulting in an efficiency improvement and a potential power reduction.
THERMAL-XR® is powered by GMG Graphene. PATENT PENDING
About GMG
GMG is a clean-technology company which seeks to offer energy saving and energy storage solutions, enabled by graphene, including that manufactured in-house via a proprietary production process. GMG has developed a proprietary production process to decompose natural gas (i.e. methane) into its elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications.
The Company's present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications. In the energy savings segment, GMG has focused on graphene enhanced heating, ventilation and air conditioning ("HVAC-R") coating (or energy-saving coating), lubricants and fluids.
In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries ("G+AI Batteries").
GMG's 4 critical business objectives are:
Produce Graphene and improve/scale cell production processes
Build Revenue from Energy Savings Products
Develop Next-Generation Battery
Develop Supply Chain, Partners & Project Execution Capability
