BLACKLEAF is a France-based company that aims to make graphene affordable and enable the industry to reshape products with a greener and more efficient approach.
The company produces Few Layer Graphene (FLG) based on a proprietary method. BLACKLEAF says its process results in high quality materials that is dispersed in a 98% water-based solution.
Brazil-based Boomatech produces graphene, graphene oxide and r-GO materials. The company developed its own production (a mix of Hummers + Tours + proprietary knowledge). The company's GO production capacity is around 100 Kg per month.
Boomatech also develops graphene-based applications, currently focused on graphene batteries.
Founded in Sweden in 2017, Bright Day Graphene (BDG) strives to offer high performing materials without harmful environmental impacts.
Carbon Gates Technologies (CGT) is an early-stage company that was spun-out of Texas A&M University in 2018.
CGT produces high quality graphene flakes (GNPs). The company says that its proprietary graphite exfoliation production process results in large graphene nanoplatelets, with very low D/G peak.
Carbon Nano-Material Technology is a South Korean refined graphite and graphene carbon materials manufacturer. It holds several patents and further patents pending relating to processes for the manufacture of these materials at significantly lower costs than other manufacturers.
The company is already said to be selling value added graphite products in the market using its proprietary portfolio of technologies. Carbon Nano-Material Technology has developed mass-production technology at a cost of 20 to 30% of existing technology in-house for the first time in the world by enhancing catalyst production and synthesis in the existing production process of carbon nano-material
US-based 
Carbon Research and Development Company (CRDC) produces graphene materials, derived from bio-mass. CRDC's materials are branded as Xphene.
France-based Carbon Waters produces graphene materials using a unique patented process that produce high-quality graphene in water dispersion.
Sri Lanka based Ceylon Graphene Technologies was established in June 2018 as a joint venture of the LOLC Group and the Sri Lanka Institute of Nanotechnology (SLINTEC). CGT produces high-quality graphene and other carbon materials using Sri Lanka graphite.
Charmgraphene, based in Korea, is producing graphene materials - both CVD graphene (using a roll-to-roll facility) and graphene flakes. The company's R2R production system can produce 2 meters of CVD graphene per minute (maximum width 300 mm).
The company also offers custom-built materials production equipment, such as ALD, Evaporators, and more.
Carbonext is based in Oklahoma, specializing in commercial graphene technology applications.
