GEM Graphene Masterbatch and GraphCore Graphene

Black Swan Graphene is a graphene producer headquartered in Toronto, Canada and listed on the TSX Venture Exchange, with a commercial production facility for graphene nanoplatelets in Consett, United Kingdom. Its production technology was acquired from Thomas Swan, a UK specialty chemical manufacturer, and the company aims to make graphene a practical, low-cost additive for plastics and concrete.

Its GraphCore powders and dispersions supply graphene to compounders, while GEM masterbatches let moulders add graphene to standard compounds at loadings typically below 1% in injection moulding or extrusion. A graphene concrete and cement admixture targets stronger, lower-material construction. The company works with masterbatch makers, compounders and distributors in Europe, the Americas and Brazil, and in 2026 acquired injection moulder Falpaco to build a vertically integrated platform.

• GraphCore: graphene nanoplatelet powders and dispersions for compounders and manufacturers.
• GEM masterbatch: ready-to-use graphene masterbatch at loadings typically below 1%.
• Fast customisation: tailored loading and resin mixes with typical two-week turnaround.
• Concrete admixture: graphene additive for stronger, lower-carbon concrete and cement.
• UK production: expanded graphene nanoplatelet facility in Consett, United Kingdom.
• Patented process: bulk production technology for 2D materials covered by 16+ patents.

Plastic packaging and injection moulding companies in Vietnam can trial GEM masterbatch to reduce wall thickness while keeping strength. Masterbatch and compound producers can add graphene grades to their portfolio. Ready-mix concrete suppliers can test the graphene admixture for infrastructure projects that require higher strength.

GEM masterbatches can be let down directly into existing compounds, giving tensile strength gains that allow lightweighting, plus better barrier properties and thermal conductivity, with custom formulations typically turned around in about two weeks. The company states that graphene can improve tensile performance by up to 30%. Its concrete admixture is described as delivering 25-30% higher compressive strength and up to 30% less material use.

Brand owners and automakers want lighter, stronger plastic parts and packaging with less material, while the construction industry seeks lower-carbon concrete. Graphene masterbatches let processors adopt nanomaterials without new equipment. Vietnam's large plastics, packaging and construction materials industries are potential adopters as export customers raise sustainability requirements.
