A single kilogramme of its product might not sound significant - but the order from a major aerospace firm could spell take off in the US for its product.

The Cheltenham firm at the forefront - worldwide - of the fast-growing market for graphene has revealed its nano-platelet product has unlocked the door into one of the world-s biggest markets.

AIM-listed Versarien plc has announced it has won an order for its graphene nano platelets from a design and manufacturing company for use in fire retardant aircraft interior parts for an unnamed "major global airline".

The order is for an initial one kg of its product.

"It is anticipated that further orders will be received to fulfil the end-customers contract," said a statement from the company.

The specific aircraft interior parts have gained the necessary certification from a USA-based, Federal Aviation Administration (FAA) certified, fire testing laboratory.

Neill Ricketts, CEO of Versarien, said: "We are very pleased to have received this order for our graphene nano platelets for an application that is in a new area for Versarien.

"This order demonstrates further industrial traction for using graphene in various applications. We look forward to working with this customer and with others to develop commercial products in the aircraft interior sector that could be enhanced by the use of graphene."

Graphene is described as single layer of carbon atoms arranged in a hexagonal lattice which forms a super strong, super conductive, flexible, flame retardant material.
