First Graphene (FGR) has reported that Foster Plastics Industries, an Australian extrusion company, is collaborating with FGR to develop PureGRAPH-enhanced ethylene-vinyl acetate (EVA) materials for use in Foster’s range of solar tubes and plastic extrusion systems.
The PureGRAPH 10 EVA masterbatch loaded with 30% graphene will be drawn down to the desired ultimate concentration of 0.25% to 1% within Foster’s proprietary black nitrile/PVC compound.
EVA is a versatile master-batching material which is used to incorporate functional additives into various compounds, in this case PVC. FGR mentioned that earlier work in collaboration with the Graphene Engineering Innovation Centre (GEIC) in the UK, demonstrated that PureGRAPH can be effectively loaded into EVA even at these high levels of 30% weight per weight basis. The incorporation of high performing PureGRAPH graphene will seek to improve solar tubes for water heat conductivity, tensile strength, compression strength and longevity in UV exposure.
The successful incorporation of PureGRAPH into Foster’s materials at their Yatala factory in Queensland will enable the Company to evaluate the products within its business lines which will benefit from PureGRAPH. Masterbatches have been dispatched for manufacturing and testing will commence immediately.
