P1 Graphene targets areas like lowering vehicle weight to reduce emissions and improve fuel efficiency. Its solutions are focused on manufacturing graphene-enhanced composites in the application of carbon fiber, polymer matrix composites and rubber tires.

GraphenTech

GraphenTech logoNetherland-based GraphenTech was established in 2016 with an aim to become a graphene producer, using technologies developed at several Universities in Europe, Russia and Latin America.

GraphenTech aimed to establish a blockchain-based security system that was supposed to allow it to raise capital and initiate trading in graphene based on its tokens. The company's was planning to do an ICO in October 2018.

Hengli Shengtai (Xiamen) Graphene Technology

Hengli Shengtai (Xiamen) Graphene Technology (associated with Angstron Materials' Dr. Bor Jang) was established in 2016 in Xiamen, China, to produce graphene raw materials and graphene applications.

The Company reportedly had a production capacity of 100 tons of graphene, with plans to increase the production capacity to 300 tons and eventually 5,000 tons in 2020.

CellsX
