FAQs

GNPs are ultra-thin, multi-layered graphene flakes that enhance mechanical, thermal, and barrier properties in materials like polymers, coatings, composites and concrete.

GNPs offer a balance of performance, dispersibility and affordability, making them ideal for industrial-scale applications.

Blacks Swan Graphene use a process of High Shear Liquid Phase Exfoliation (HSLPE) using a number of patented processes. The core process uses a patent licensed from Trinity College Dublin, where BSG is the sole licensee, supported by a number of process patents granted across the globe utilising our internal intellectual property.

Typical benefits seen in multiple applications areas are:

• Barrier enhancement: Reduces gas, moisture and hydrocarbon permeability (ideal for packaging).
• Mechanical strength: Improves tensile strength and durability in polymers.
• Lightweighting (often referred to as downgauging): Increase in strength with minimal addition allows reduction in use of core polymer.
• Abrasion resistance: Improves the abrasion resistance of moving parts
• Chemical and U.V resistance: Improves Chemical and U.V resistance of plastics

• Packaging: Improved barrier properties (oxygen/moisture resistance) such as PET bottles
• Automotive: Lightweight, durable components.
• White goods: Lighter and long-lasting parts with improved wear and tear resistance.
• Gasoline and chemical containers: With improved chemical resistance and permeability especially against gases and hydrocarbons
• Textiles: Enhanced PET and PA fibres (e.g., sportswear).
• Footwear:  lighter footwear parts with improved wear resistance
• Industrial parts and conveyer belts:
• Compostable and bio polymers: To enhance the barrier properties of compostable polymer compounds such as PLA, PBAT, PHA
• Coatings and Paint industry: To produce long lasting paints and for corrosion resistance applications

• Cement & Concrete: Reduced cracking, higher tensile strength. Lower CO₂ emissions via reduced cement use.

BSG’s GNPs are optimized for mechanical, barrier properties and thermal conductivity. Higher loading/ let down ratios of GNP is required for electrical conductivity.

Yes. Our GNPs comply with REACH, OSHA, and industry safety standards.

Through melt compounding, or by adding readily available of masterbatches (GEM).

GEM™ is a pre-dispersed graphene masterbatch that simplifies graphene integration into polymers. It ensures uniform dispersion without pre-processing.

Until recently, using graphene had been difficult, since it was expensive and difficult to disperse. Using GEM™ from our approved masterbatch partners reduces that barrier to entry with low-cost masterbatches that can be let down to typical loading levels of 0.1~1.0% GNP in final compound.

Experienced OEMs may well be comfortable with handling powder, but generally GEM™ eliminates complex dispersion steps, saving time and ensuring consistent performance making a graphene trials quicker and easier, reducing barrier to entry.

• Ease of use: Ready-to-process pellets.
• Consistency: Uniform graphene distribution.
• Performance: Enhances strength, thermal stability, and barrier properties.

Please see the Products page each dispersed in a typical resin (e.g., TPU, PET. HDPE, PP, PA). The “standard” GEM™ allows let-down into a specific polymer to investigate the performance. Often this will suffice in noncritical applications, but where specific features are required a customer GEM™ can be prepared typically in a couple of weeks with specific polymer resin.

Yes. We work with clients to tailor graphene loadings and polymer bases.

GEM™ solutions are compatible with standard methods like injection moulding, extrusion, rotation and blow moulding.
