Graphene Fire Retardant Demonstration

Posted By Terrance Barkan, Friday, December 15, 2017

Advanced materials company, First Graphene Limited (FGR), has provided an update on its development of the graphene based FireStop™ fire retardant material.

Development of the FireStop™ material is being conducted in conjunction with the University of Adelaide as part of the Company’s participation as a Tier 1 participant in the ARC Research Hub for Graphene Enabled Industry Transformation.

The video below shows the dramatic effectiveness of FireStop™when applied to simple wooden structures. Whereas the untreated structure on the left is totally consumed by fire, the structure treated with the FireStop™ retardant doesn’t even catch fire even after five minutes of trying to light it with a blow torch.

Given that fires generally start at specific ignition points, the ability of a graphene-based retardant to stop the ignition is a key feature of the product. The FireStop™ was applied in three coats, was applied by brush and was less than 500 μm thickness.

 

 Note: There is no sound for this video.


The relevant characteristic of graphene that this demonstration highlights is the very high thermal conductivity i.e. the ability to disburse heat away from the source. FGR is highly encouraged by the results of this simple demonstration, which augers well for subsequent, more advanced and scientifically controlled demonstrations that are being undertaken.

The University of Adelaide has now received a UL-941 system for use in its workshop. It is also installing an LOI instrument for the generation of scientific data. These instruments will enable an acceleration of the test work being conducted to optimise the FireStop™ product and application methodology.

[ UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. The standard determines the material’s tendency to either extinguish or spread the flame once the specimen has been ignited. UL-94 is now harmonized with IEC 60707, 60695-11-10 and 60695-11-20 and ISO 9772 and 9773. ]

Further tests will be conducted to increase the viscosity of the product while maintaining the fire-retardant performance. This work will be the precursor to submitting FireStop™ to FGR’s own testing to the relevant fire standards and to CSIRO for independent testing in Q1 2018. In the meantime, the Company is entering negotiations with potential industry partners for the commercialisation of FireStop™.

FGR is a Corporate Member of The Graphene Council, we congratulate them on their continued commercial development!

This would go really well with our flame proof graphene insulation.
