The application of Directa Plus's technology to rubber-based shoe soles allows manufacturers to balance the conflicting properties of durability and grip in both wet and dry conditions, a characteristic already demonstrated by the company in its formulations of G+® for the tyre and retread markets.
The company said the grant is a further strengthening of its intellectual property portfolio which now comprises 56 patents in total: 33 granted and 23 pending, covering Directa Plus's production process and developed products and applications.
In a statement, Giulio Cesareo, founder and CEO of Directa Plus commented: "The ability of our G+® graphene to balance the opposing characteristics of wear and grip for rubber based products such as tyres and shoe outsoles is proving to be of great interest to manufacturers.
"We aim to build a strong intellectual property portfolio and we will continue to seek patent protection for our processes, products and product applications."
