Scientists at the University of Manchester first isolated flakes of graphene in 2004, winning them a Nobel prize in physics 6 years later. The many superlative properties of the material have led to thousands of scientific publications and patents every year in this new and exciting area of research.

Graphene is a one-atom-thick honeycomb of carbon atoms with world-beating mechanical, thermal, optical and electrical properties. It has already been used for flexible electronics, energy storage, nanocomposites, sensors, liquid filtration and thermal management.

GPS has a polymer matrix that contains graphite. The high-purity graphite particles are introduced into the raw material, polystyrene beads, which are heated at high temperatures and then treated with steam to create the cellularly dense structure in a similar way to standard polystyrene. The inclusion of graphite particles helps to increase the foam's resistanceto the flow of heat by reflecting heat energy to a greater extent than standard polystyrene.

In terms of fire, there is some evidence that graphite can improve resistance to the spread of fire, while other studies have also looked at Expanded Graphite Coating on Polystyrene Bead for Improving Flame Retardancy. The indication is that most graphite polystyrenes are also treated with a fire retardant, although this is unclear and may vary from product to product.
