Australian oceanic farming supply company Hexcyl Systems has partnered with First Graphene Ltd. on the production of graphene-filled high-density polyethylene (HDPE) materials to improve the strength of long-line farming systems, such as baskets for catching oysters.
The addition of First Graphene’s PureGRAPH product saw an immediate uptick in the baskets’ resistance, longevity, and strength, confirming graphene’s potential for the application.
According to Craig McGuckin, First Graphene Managing Director, “A low dosage of less than one per cent of PureGRAPH has generated an increase in yield strength of more than 60 per cent, when compared to the base HDPE product.”
“Samples showed a more than 10 per cent increase in ultimate tensile strength and at the same concentration, abrasion loss was reduced by more than 50 per cent.”
Graphene has been used as an additive in plastic before to bolster their strength and resistance to electricity, heat, chemicals, gas, and more. The hope is that by adding graphene, cheaper, less durable plastics can take on the higher-strength capabilities of more expensive plastics.
Such enhanced plastics could have implications in the automotive and aerospace industries, as well as mass transport, construction, and oil & gas.
