Nanoxplore launches graphene powder xGnP D500-HP

NANOXPLORE LAUNCHES XGNP D500-HP, HIGH-PURITY GRAPHENE TO REPLACE CONVENTIONAL CONDUCTIVE ADDITIVES

Nanoxplore Inc. has launched xGnP D500-HP, a high-purity graphene powder engineered for highly conductive applications, including, but not limited to, energy storage, conductive composites and advanced electronics. The D500-HP is the latest demonstration of the company's ability to develop graphene materials to meet the needs of specific end-uses.

D500-HP is produced through Nanoxplore's proprietary dry-process manufacturing platform, with verified purity of 99.8 per cent at full commercial volumes. With a surface area of 500 square metres per gram, at the high end of commercial-scale graphene powders, D500-HP delivers electrical conductivity and static-dissipation performance comparable with leading conductive carbon blacks while providing more than twice the flexural (bending) strength and stiffness. The result: Customers no longer need to trade strength for conductivity.

D500-HP will be priced competitively with conductive carbon blacks, giving customers graphene-level performance without a graphene-level premium.

Initial customers have validated the performance data of the D500-HP, and broader qualification programs with target customers are under way. The company expects initial commercial shipments to commence in fiscal 2027.

"For years, conductive additives have forced customers to choose between strength and conductivity, and graphene alternatives have been priced out of mainstream use. The D500-HP breaks both constraints," said Rocco Marinaccio, president and chief executive officer of Nanoxplore.

Dry-process production line update

Nanoxplore also reported continued progress on the scale-up of its dry-process production line. Installation of the first production module, including mechanical and electrical work, has been completed on schedule and within budget. Depending on product grade, the line is designed to deliver annual production capacity of 500 to 1,000 tonnes, supporting industrial-scale supply of D500-HP and future grades in the xGnP D-series.

The dry-process platform enables a broader range of application-specific graphene grades engineered to match the performance requirements of specific end-uses. This materially expands the company's opportunity to capture market share from specialty and conductive carbon blacks -- a multibillion-dollar, fast-growing segment of the carbon black industry -- and from incumbent additives in adjacent performance markets.
