PureGRAPH® significantly improves rubber polymers used in the mining sector

Posted By Graphene Council, Wednesday, September 2, 2020
First Graphene Limited (“ASX: FGR” or “the Company”), is pleased to provide an update on the incorporation of PureGRAPH® into rubber compounds for applications in the mining sector.

As reported in March this year, FGR commenced work on the manufacturing of PureGRAPH® powders into long-chain rubber polymers.

To leverage customer interest, FGR concentrated on the compound most commonly used in the mining screen media market, with potential to adapt the findings into other sacrificial wear-liner rubber materials across the industry. The work has been conducted in conjunction with an experienced rubber consultant in Perth and an established rubber processor in Ipoh, Malaysia.

First Graphene Managing Director, Craig McGuckin says the results from the extensive test work undertaken are encouraging.

“The initial work demonstrates a low dosage of PureGRAPH® provides improvements over the base material most commonly used for the mining screen media market,” McGuckin said.

“Further tests will be undertaken with the PureGRAPH® compounded rubber for both mining screen and sacrificial wear media, as this is a large market and one in which we are actively engaged with both suppliers and end users.

“The results so far provide the platform to introduce PureGRAPH® into other compounded rubber materials both in industrial and domestic use.”

Initial Science

FGR engaged an experienced rubber consultant to understand the science associated with the compounds used in the mining screen and wear media markets.

Rubber compounds vary considerably depending on their use. Screening tests were completed on 35 compounds using formulation variations and compounded on a laboratory scale two-roll mill, similar to that in Figure 1.

The two-roll mill allowed for multiple small batches of rubber to be produced with adjusted PureGRAPH® concentration and rubber chemistry. A range of mechanical testing could then be carried out on each batch to evaluate performance and produce the following data displayed in Figure 2.


Figure 2 demonstrates that multiple mechanical improvements can be achieved through low addition rates of graphene using a two-roll mill. This resulted in a better understanding of how certain mechanical properties can be tailored for specific applications through adjustments to the graphene concentration and rubber chemistry.

Upscaling of Test Work using PureGRAPH®

Laboratory testing demonstrated the benefits for numerous graphene enhanced rubber compounds using a two-roll mill.

Laboratory scale equipment does not fully resemble the processing conditions present in full scale commercial rubber compounding, typically carried out in large internal mixers followed by industrial two-roll mills, and so it was important to upscale the laboratory testing to better simulate commercial rubber compounding and demonstrate the benefits of graphene under this environment.

For the commercial scale tests, a control rubber was selected based on industry compounding experience, demonstrating the desired mechanical properties of a typical hard rock screen or wear liner application.

A production scale run of this material was then compounded using the Malaysian partner’s commercial production process line, both with and without the addition of PureGRAPH®. The compounded rubber was then moulded into large prototype parts and test sheets for mechanical testing.

Results from PureGRAPH® enhanced rubber

The following table outlines the improvements achieved from the incorporation of PureGRAPH®20 in the base material used for mining screen or wear media compounds.
 
The improvement in abrasion resistance (i.e. decrease in abrasion wear over the base material) and tear strength is of particular importance for improved performance and longevity of screen media.

As detailed in Table 1, both abrasion resistance and tear strength can be significantly improved through a low addition rate of PureGRAPH® into the rubber compound.

Client compounded PureGRAPH® enhanced rubber screens are currently in field trials in the mining industry in Western Australia.

Further laboratory test work is underway on additional rubber compounds and processing techniques focussing on improved compound dispersion and fire-retardant applications. Updates will be provided as this work is completed.

First Graphene Announces Study Shows Concrete is Enhanced with Graphene

Posted By Graphene Council, Thursday, August 20, 2020
First Graphene today released a technical update on the application of its proprietary PureGRAPH® graphene as an additive in cement grouts and concrete.

The study shows that graphene admixtures increase strength, reduce materials usage (reducing carbon footprint) and potentially increase longevity of products. This analysis is noteworthy since cement is estimated to amount to 6% of all CO2 emissions from human activity.

Cement is the most manufactured and traded product globally after water, which is causing enormous climate change challenges to reduce its carbon footprint. In 2015, the total mass of cement produced was 4.6 billion tonnes. This is equivalent to about 626 kg per capita, a value higher than the amount of human food consumption.

With population growth, increased urbanisation and improved living standards of the global population, the demand for concrete products continues to grow at an accelerating rate.

First Graphene Managing Director, Craig McGuckin says:
“The initial work demonstrates a low dosage of PureGRAPH® generates an increase in compressive and tensile strengths, when compared to the base product,”. Mr. McGuckin further stated “While there is a considerable amount of further work to be done, this is very encouraging for enhancing the performance of concrete both new and recycled, but equally the sustainability benefits for the environment.”

Research Partnership with University of Warwick

Posted By Graphene Council, Wednesday, July 29, 2020
First Graphene today announced a research collaboration with world-leading experts at the University of Warwick to enhance the understanding of graphene in a range of polymer systems such as plastic and rubber.

The PhD Project will be conducted under the Warwick Collaborative Post Graduate Research Scholarship Scheme, in conjunction with the Warwick Manufacturing Group (WMG) that has established a world- recognised model for successful collaboration between academia and the private and public sectors. WMG has strong links with world-leading industrial partners such as Jaguar Land Rover, who announced in late 2019 they were relocating their advanced research group to the facility.

First Graphene will collaborate with the University’s Professor Tony McNally, who have established capability in incorporating nanomaterials, including carbon nanotubes and graphene into bulk polymer systems.

Using graphene as an additive in thermoplastic materials gives an improvement in properties such as mechanical, electrical, thermal, fire retardancy, chemical resistance and gas barrier. This provides the potential to move lower cost polymers such as polyolefins and polyamides up the “plastics performance pyramid,” creating new value for plastic manufacturers. Potential uses for these enhanced engineering plastics are light-weighting in automotive and aerospace as well as the delivery of a new generation of high-performing fire-retardant plastics in mass transport, construction, mining and oil & gas.

The project will combine WMG’s capability and First Graphene’s operational experience of graphene production and processing to investigate and optimise the impact of surface chemistry, the use of additives and optimising the mixing process technology to deliver further improvements in the properties of graphene-enhanced polymers. Existing First Graphene customers will benefit from this research, which will also enable a new range of PureGRAPH® enhanced polymer and rubber systems.

First Graphene Managing Director Craig McGuckin says this new collaboration is significant and necessary. “It reaffirms our position as the leading graphene producer and innovator. We recognise Warwick University and Warwick Manufacturing Group’s world leading expertise and our need to keep investing in collaborative projects to keep delivering improvements,” Mr McGuckin said.

“This research, which will comprise a PhD project over a three-and-a-half year period, will unlock graphene’s potential to improve strength, durability and the lifespan of a range of polymer systems.” Professor McNally, who is Professor in Nanocomposites and Director of the International Institute for Nanocomposites Manufacturing (IINM) at WMG, says he is delighted to be collaborating with First Graphene on this fundamental research.

“I look forward to working with their research team on this project which will drive real benefits in the industrial use of thermoplastic materials in a range of real-world applications,” Professor McNally said.

Mr McGuckin says using graphene as an additive in thermoplastic materials improves mechanical, electrical, and thermal properties particularly in the areas of fire retardancy, chemical resistance and gas barriers. “This provides the potential to move lower cost polymers such as polyolefins and polyamides up the so-called `plastics performance pyramid’ creating new value for plastic manufacturers.”

The Warwick Manufacturing Group (WMG) has a world-recognised model for successful collaboration between academia and the private and public sectors.
