Graphite specialist NeoGraf Solutions has launched a new range of graphene nanoplatelets (GNP) and graphene precursors (GP) for plastic thermoset and thermoplastic applications.

GNPs are ultra-thin, multilayer graphene nanoplatelets made with graphene, a single layer of carbon atoms arranged in a hexagonal matrix that is high strength, super thin, and offers the highest electrical and thermal conductivity, according to the company. GPs are graphite products designed specifically as a raw material for high-volume production of graphene products through further processing.

NeoGraf says that its Graf-X GNP and GP products can improve the mechanical strength, electrical conductivity, and thermal properties of thermosets and thermoplastics such as polypropylene (PP), polyamide (PA), polystyrene (EPS and XPS), polyethylene (HDPE, LDPE, LLDPE), polyvinylchloride (PVC), and polyethylene terephthalate (PET). They can reportedly increase the toughness of plastics by up to 2.5 times without a significant weight increase. In composite formulations, loadings of <5 wt% of graphene can increase strength by 40%, improve stiffness by 20%, and elevate impact strength by 80%. Graphene can also improve the heat resistance of composites and provide noise reduction of up to 20%, the company said.

The graphene materials can be used in a range of plastic applications such as electrically conductive fillers for electrostatic discharge (ESD) plastics in automotive and aerospace electronics, and heat resistance additives for under-hood plastic components such as HVAC systems, water pump housings, and valve covers.
