Luxembourg-based OCSiAl, the global leader in industrial synthesis of graphene nanotubes, announces the appointment of Antigone Loudiadis as a director.

An investment entity owned by Ms. Loudiadis made a substantial investment in OCSiAl at the end of 2025. This investment followed an investment earlier that year by a Luxembourg “club” of investors.

Ms. Loudiadis founded and led Rothesay Life, one of the UK’s leading pension insurers. Prior to the establishment of Rothesay Life, Ms. Loudiadis was a partner at Goldman Sachs International and cohead of its European Investment Banking Division. Over the course of her 30-year career as a senior financial executive, she led complex structured and M&A transactions and managed senior relationships with governments and multinational institutions.

“I am very excited to be joining OCSiAl,” said Ms. Loudiadis. “It’s cutting-edge deep tech that takes established industries—like tires and coatings—to a new level. But it also goes hand in hand with the next step in the development of EVs, data centers, AI, robotics and aerospace.”

“I am delighted to have Addy on the board. She brings a rare combination of deep capital markets expertise and firsthand experience in building and governing large, capital-intensive businesses,” said Peter Cuneo, Chairman of the OCSiAl Board. “As OCSiAl accelerates its industrial scale-up and prepares for significantly larger long-term investments, her perspective will be invaluable in shaping our capital strategy, strengthening governance, and engaging with a broader base of global investors.”

As advanced materials increasingly take on strategic importance alongside energy and capital, OCSiAl’s current phase of industrial scale-up places the company at the center of this shift.

About graphene nanotubes for plastics

Graphene nanotubes are a versatile nanomaterial agent for composites and plastics. When incorporated into materials, they form a three-dimensional conductive and reinforcing network that enables stable anti-static performance suitable for ATEX / IECEx zones throughout the service life of the product. Operating at ultra-low loadings, graphene nanotubes allow manufacturers to maintain the original mechanical performance, appearance, and standard processing conditions of the base material, while supporting improved functionality, material efficiency, and sustainability.
