The difference between graphite EPS and graphene EPS!

Graphite is formed by a layer of planar carbon atoms stacked in a honeycomb-like orderly arrangement. The interlayer force of graphite is weak and it is easy to peel off each other to form a thin graphite sheet. When the graphite sheet is peeled into a single layer, this single layer, which is only one carbon atom thick, is graphene.

In 2004, two scientists at the University of Manchester, Andre Geim (Andre Geim) and Konstantin Novoselov (Konstantin Novoselov) used special tape to prepare graphene from graphite. In 2009, Andre Gaim and Konstantin Novoselov discovered the integer quantum Hall effect and the quantum Hall effect at room temperature in the single-layer and double-layer graphene systems, respectively. They also won the 2010 Nobel Prize in Physics.

Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery, and is considered to be a revolutionary material in the future.

In terms of tensile strength, graphene EPS is 2-3 times that of graphite EPS, and the use of graphene EPS can reduce the bulk density of at least 5kg in construction projects. The use of graphene EPS in the packaging field can improve the turnover rate of its packaging products and reduce the loss of goods caused by packaging damage during transportation.

The thermal conductivity of graphene EPS is less than or equal to 0.030W/(m · k), while the thermal conductivity of graphite EPS reaches 0.032W/(m · k). This means that the same thermal insulation effect, graphene polystyrene board than graphite polystyrene board thickness reduction, while saving a lot of transportation costs.

In terms of fire resistance, both of them do not have fire resistance, and both need to add flame retardants to achieve fire resistance. Whether graphite EPS or graphene EPS can achieve fire rating B1.
