Technical Information 

Graphene consists of a single layer of carbon atoms arranged in a hexagonal structure. However, single-layer graphene is rarely used in thermoplastics due to the high cost of manufacture. Instead, commercially available graphene typically comprises 5, 10, 20, 30, or even up to 50 layers, although Hubron generally uses graphene with fewer than 10 layers. When stacked, these layers form what is known as few-layer graphene, which is typically less than 2 nm thick.

The unique two-dimensional morphology of graphene can significantly improve the mechanical properties of thermoplastics. The degree of enhancement depends on factors such as lateral size, number of layers and dispersion quality. These improvements are particularly valuable in applications requiring lightweighting, improved flexibility and better processability.

Graphene also exhibits excellent barrier properties, improving the permeation resistance of thermoplastics. Its 2D structure and high aspect ratio reduce the transmission of gases such as nitrogen, carbon dioxide, oxygen and even hydrogen. This makes it especially relevant for applications such as pipes, packaging, membranes and hydrogen fuel systems.

In addition, graphene can act synergistically with phosphorus-based flame retardants to promote char formation, reducing the fuel available to a fire. The inclusion of graphene can allow for lower flame-retardant loading, which in turn helps maintain or improve the mechanical properties of the thermoplastic.

Another promising area of development is the use of graphene in electromagnetic shielding. Traditionally, metals have been used for this purpose, but graphene’s unique morphology, when combined with traditional carbon black, can significantly enhance shielding effectiveness in thermoplastics. This innovation is gaining traction with the rise of the EV market and the miniaturisation and expansion of electronics.
