Graphene delivers step-change in HDPE performance

Posted By Graphene Council, Monday, August 10, 2020
Working closely with Hexcyl Systems Pty Ltd. a leading supplier of systems for oceanic farming, First Graphene Ltd. has demonstrated improvements in the performance of High-Density Polyethylene (HDPE) materials. Hexcyl Systems Pty Ltd. will now progress to advanced trials, making super-strong HDPE oyster baskets for long-line farming systems.

Using First Graphene’s PureGRAPH® products the High-Density Polyethylene (HDPE) showed improvements in strength, wear resistance and longevity. The initial results, confirm the potential of PureGRAPH® graphene as a high performing additive for the global HDPE industry.

HDPE is a thermoplastic polymer widely used in packaging (cosmetics, food and beverages), corrosion-resistant piping, geomembranes and plastic timbers. The global market for HDPE was estimated at USD 59 Billion in 2015, with a CAGR of 4%[i].

Craig McGuckin – Managing Director, First Graphene Ltd. believes this an important first step for PureGRAPH® products into this important global market.

“This trial confirms that PureGRAPH® graphene products successfully enhance the performance of HDPE materials in industrial applications. This is an important milestone in our strategy to develop additives for thermoplastic materials”. said Mr McGuckin.

The capability of First Graphene PureGRAPH® technology enabled significant mechanical improvements.

“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,” said Mr McGuckin.

“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.”

The project will now move to a larger scale trial in real-world, ocean conditions, commencing in August 2020.

First Graphene Ltd and Hexcyl to Collaborate on HDPE Project

Posted By Graphene Council, Thursday, May 7, 2020
First Graphene Limited is pleased to advise that Hexcyl is collaborating with the Company to develop PureGRAPH® enhanced HDPE materials for use in Hexcyl’s range of oyster baskets and long-line farming systems.

High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic timbers.

The incorporation of high-performing PureGRAPH® additives will seek to improve the mechanical properties of the HDPE, while at the same time provide greater longevity of the systems in high energy farming environments.

Hexcyl Systems offer oyster farmers and shellfish farmers a wide range of shellfish aquaculture products designed for Adjustable Longline Shellfish Farming and other tidal systems. The products are manufactured in Australia and sold globally.

PureGRAPH® additives will be supplied to Hexcyl’s masterbatch and injection moulding companies over the next two weeks.

Craig McGuckin, Managing Director for First Graphene Ltd., said, “Working with Hexcyl Systems with their requirement for additional mechanical improvement is yet another industry where PureGRAPH® may provide benefits to material enhancement”.
