Ltd, Panthera combines excellence in the manufacture of expandable graphite with distribution to global tier-1 players in the global graphite industry.

Metachem Manufacturing
Metachem are the first “Flame Retardant Specialists”, since 1964, producing Expandable Graphite! We export to Europe, UK, USA, Australia, Southeast Asia and more! We believe in strong customer support, a dedicated R&D team, and customised solutions!

Evion Group
Evion Group (ASX:EVG) is a vertically integrated graphite developer with projects being developed in both Madagascar and India.
The Company holds the flagship Maniry Graphite Project, which is located in Southern Madagascar, with the Bankable Feasibility Study (BFS) recently completed and has been identified as one of the key regional mining projects to be fast tracked into development over the next year.
Operating under Australian environmental and general governance standards, the company will benefit from the close, long standing, multi-faceted relationship in the resources sector between Australia and India.
Panthera Graphite finalised construction of its development in April 2024. Since then, Panthera Graphite has begun producing expandable graphite from India, a country with a number of decades of experience, with the first order to be shipped to Europe over the forthcoming months.
The JV has already commenced planning for an upgrade to production that has the potential to more than double sales volumes and revenue. This is in response to very strong demand which could see the JV become one of the world’s largest producers of Expandable Graphite outside of China, supplying markets in Europe, the USA and southeast Asia.
