HOLTON, United Kingdom, March 17, 2026 (GLOBE NEWSWIRE) -- HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) (“HydroGraph” or the “Company”) today announced that Broadway Colours Ltd. has earned certification as a qualified HydroGraph Compounding Partner following completion of HydroGraph’s rigorous technical and commercial qualification process, further strengthening HydroGraph’s commercial presence across the UK and European plastics markets and expanding the Company’s ability to support large-scale commercial adoption of graphene-enhanced polymer materials.

Broadway has earned certification as a qualified HydroGraph Compounding Partner, having successfully completed HydroGraph’s rigorous qualification testing with strong results. The certification process evaluates dispersion capability, processing performance, quality control standards, and commercial readiness to support graphene-enhanced formulations at scale. Broadway has already demonstrated its commercial readiness in the graphene market by launching GrapheneXcel^TM, its proprietary range of graphene masterbatches designed to improve mechanical performance, conductivity, and barrier properties in polymer systems.

HydroGraph’s Fractal Graphene™ materials, including its flagship FGA-1 product, are engineered to deliver performance improvements at significantly lower loading levels compared to conventional nanoplatelet graphene materials. The partnership supports HydroGraph’s strategy of enabling commercial adoption of graphene through a qualified network of compounders capable of integrating Fractal Graphene™ into scalable thermoplastic formulations. Global demand for advanced composite materials continues to grow across automotive, packaging, electronics, and infrastructure markets, where manufacturers seek lighter, stronger, and more sustainable material solutions.

“Broadway has demonstrated both technical capability and commercial readiness for graphene-enhanced materials,” said Kjirstin Breure, President and Chief Executive Officer of HydroGraph. “Certified compounding partners play a critical role in accelerating graphene commercialization by translating advanced materials into scalable industrial formulations. Their ability to move quickly from formulation to production supports faster customer adoption of Fractal Graphene™ in high-value applications across polymer applications such as packaging, construction materials, and industrial components where performance, durability, and material efficiency are critical.”

“We are proud to have achieved certification as a HydroGraph Compounding Partner,” said Stephen Rayner, Technical Director of Broadway. “Our experience in advanced masterbatch formulation and underwater pelletising technology enables consistent dispersion of graphene at low addition rates. We look forward to supporting customers seeking enhanced mechanical and functional performance in polymer applications through the integration of Fractal Graphene™.”

Founded in 1997 and located in Holton, Suffolk, Broadway is a leading UK manufacturer of masterbatches, compounds, and rotational moulding powders, operating from a 90,000-square-foot facility. Broadway supports plastic manufacturers throughout the UK and Europe.
