- Advanced materials group Haydale Graphene Industries said the results of a trial in March with Amiblu Technology did not show hoped-for improvements.

Haydale said it was continuing discussions with the Ambilu R&D team and planned to hold a meeting in the fourth quarter to discuss next steps.

Saudi Arabia's Amiblu had partnered with Haydale in 2016 to develop reinforced plastic products.

Haydale also announced that it had extended a supply contract with a 'global industrial manufacturer' amounting to over $3.3m.

The five-year extension would involve supplying silicon carbide micro-fibre to a group selling tooling and wear-resistant solutions.
