HydroGraph Clean Power says a peer-reviewed study found its graphene aerosol coating increased copper’s heat transfer coefficient by 152%, a result the company is framing as a scalable route to thermal management for electronics, data centers and other high-power systems.
A March 27 Nature Communications paper is putting a high-profile graphene thermal conductivity claim under the microscope, arguing that the reported performance was likely overstated and that the experimental setup may have distorted the result. The dispute matters because thermal management remains one of graphene’s most commercially important promises.
Graphene Manufacturing Group has received U.S. Environmental Protection Agency approval for the import and sale of its THERMAL-XR graphene coating in the United States, clearing a regulatory hurdle that had blocked commercial sales in the country. The decision gives GMG and distributor Nu-Calgon the right to begin shipments into the HVAC-R market, with applications also cited for data centers, electronics and other industrial uses.
Graphene Manufacturing Group has secured U.S. EPA approval to import and sell its THERMAL-XR graphene-based coating in the United States, a regulatory step that allows commercial sales to begin in the country’s large HVAC-R market and broadens the product’s path into other thermal-management applications.
Graphene Manufacturing Group has won U.S. EPA approval for its THERMAL-XR graphene-based coating, a regulatory step that allows the company to begin selling the product in the United States after years of development and earlier overseas approvals.
Graphene Manufacturing Group has cleared a major U.S. regulatory step for its THERMAL-XR ENHANCE coating, a graphene-based product designed to improve heat transfer on cooling coils and other thermal systems. The company says it accepted the EPA’s consent notice approval conditions on December 22, 2025, giving the product a path toward broader U.S. commercialization after earlier case-study work on HVAC and heat-exchange applications.
