CharmGraphene's R2R production system can produce 2 meters of CVD graphene per minute (maximum width 300 mm). According to CharmGraphene, its current CVD graphene capacity is about 8,000 sqm per month. The company says it uses use 6 um thick copper foil which reduces copper foil etching time dramatically compare to 35 um thickness copper foil used by other companies.

CharmGraphene is also developing CVD graphene-based heating elements. The materials are close to commercialization and are flexible, transparent, and thin (<100 um total thickness). The company targets automotive applications and consumer applications. The company is collaborating with several global companies for potential applications.
