First Graphene Locks in 3-Year UK Deal as Graphene Heat Sensor Hits Market
Key Takeaways
- First Graphene has signed a 36-month Strategic Partner Agreement with UK-based Vector Companies Group Limited, formalising a commercial framework for joint market development across graphene product applications.
- Vector's Peltyr printed heat flux sensor — incorporating First Graphene's PureGRAPH® material — has launched commercially, marking a tangible transition from R&D to live product revenue potential.
- The global heat flux sensor market is projected to reach US$455.8 million by 2034, according to Dataintelo, with Peltyr targeting construction, industrial, aerospace, automotive, HVAC, and research sectors.
- Under the agreement, Vector can introduce prospective end-users to First Graphene and purchase products directly, giving First Graphene an additional commercial channel through Vector's established network.
- No revenue figures or financial projections are disclosed in the announcement — investors should treat this as a commercial milestone, not a near-term earnings catalyst.
PureGRAPH® enters heat sensor market as Vector partnership deepens
First Graphene (ASX: FGR) has signed a 36-month Strategic Partner Agreement with UK-based Vector Companies Group Limited, coinciding with Vector’s commercial launch of its Peltyr printed heat flux sensor range incorporating First Graphene’s PureGRAPH® graphene material. The announcement represents a dual milestone: a formalised commercial framework and a live product now available on the market.
Under the agreement, Vector may introduce prospective end-users to First Graphene for its broad range of graphene products, and may also purchase products directly from First Graphene under separate purchase orders. The partnership broadens an existing relationship between the two companies and gives First Graphene an additional channel to prospective customers through Vector’s network spanning advanced materials, manufacturing, and the built environment.
This is graphene moving from the development stage into commercial reality.

What is a heat flux sensor — and why does graphene matter here?
A heat flux sensor measures the actual rate of heat passing through building materials such as walls, floors, and roofs. Rather than relying on modelled assumptions, it generates real measured data about how a structure actually performs thermally.
Central to this is the U-value, a standard measure of how readily heat passes through a structure. A lower U-value generally indicates better insulation performance. Historically, building owners and retrofit assessors have had to rely on modelled estimates rather than measured figures. Peltyr addresses this directly by enabling in-situ U-value calculation — that is, a real thermal performance reading taken on-site rather than derived from design assumptions.
Graphene’s role in the sensor relates to what CEO Michael Bell describes as its “unique performance characteristics.” The source does not detail specific technical parameters, but the material’s properties are presented as enabling a product that can be manufactured at scale and commercially adopted across industries.
Peltyr sensors are applicable across a wide range of sectors:
- Building physics and retrofit assessment
- Industrial process monitoring
- Aerospace
- Automotive
- HVAC systems
- Meteorology and research applications
Market opportunity and commercial strategy
According to third-party research firm Dataintelo, the global heat flux sensor market is anticipated to reach US$455.8 million by 2034, driven by growing demand across the industries listed above. The Vector partnership positions First Graphene to access this market through an established commercial channel rather than solely through direct sales.
The construction sector provides immediate structural demand. Buildings account for a significant share of global energy use, and the industry’s movement toward a lower carbon future is creating real pressure for performance data rather than design estimates. A scalable, lower-cost sensor that delivers that data has direct relevance to building owners, retrofit assessors, and housing providers.
The CEO also noted that aerospace applications are coming to light, signalling the addressable opportunity extends well beyond construction.
| Sector | Application | Relevance to Heat Flux | Notes |
|---|---|---|---|
| Construction | Building retrofit assessment | In-situ U-value measurement of walls, floors, roofs | Core market for Peltyr launch |
| Industrial | Process monitoring | Understanding heat transfer in manufacturing environments | Cited in announcement as active application area |
| Aerospace | Thermal performance monitoring | Heat flux data in high-performance environments | Described as an emerging opportunity |
| Automotive | Thermal management | Heat transfer measurement in vehicle systems | Listed as addressable sector |
| HVAC | System performance assessment | Monitoring heat exchange in heating and cooling systems | Listed as addressable sector |
| Meteorology and Research | Scientific measurement | Environmental and laboratory heat flux data | Listed as addressable sector |

CEO perspective and investment thesis
Michael Bell, Managing Director and CEO
“Peltyr demonstrates exactly what we want to achieve with our partners. By using the unique performance characteristics of graphene to solve a real industrial problem, we can develop a product that can be manufactured at scale and commercially adopted by industry.”
The broader quote from Bell also framed the strategic context clearly. He described the Strategic Partner Agreement as giving both companies a framework to identify and progress new commercial opportunities, and noted that the Peltyr launch is “an important milestone for both Vector and First Graphene…” representing “another example of our products transitioning from development into a commercial reality.”
From an investment standpoint, this partnership reflects First Graphene’s stated strategy of converting R&D relationships into structured commercial agreements with tangible product outcomes. The Peltyr sensor adds another commercially available application to the growing PureGRAPH® product portfolio, sitting alongside the company’s existing markets in cement, concrete, coatings, adhesives, sealants and elastomers (CASE), and composites.
The announcement does not disclose revenue figures or financial projections tied to this agreement, and none should be inferred. What it does confirm is that PureGRAPH® is now incorporated into a product that has launched commercially, with a formalised three-year framework governing how that relationship scales.
