Grolltex, a U.S-based graphene materials and products developer, recently closed an Internal Seed B round of financing, amounting to $600,000. The round was entirely filled by existing shareholders at a valuation of $10 Million.

The company stated that it will use the funds to improve productivity as well as for general corporate purposes. Grolltex uses patented research and technologies developed at the University of California, San Diego, to produce CVD graphene as well as develop products made of graphene.

In August 2017, Grolltex announced a large-capacity commercial lab for production of high quality CVD graphene.
