in the UK have worked with graphene producer Versarien to launch a series of Polygrene plastic compounds and masterbatches using Versarien’s Nanene graphene powders and other nanomateri- als. The researchers have looked at HDPE and at pushing the boundaries of engineering thermo- plastics. Versarien reports that mechanical proper- ties could be improved without compromising any other properties. In TPU, for example, Polygrene (at less than 1%) improved abrasion resistance. They also found improved processability, with reduced
cycle times (due to increased cyrstallisation temperature) and higher throughputs, for example. In specialty polymers such as PEEK, Polygrene significantly improves toughness. Applications could include sports equipment, construction products, and aerospace or automotive components. Versarien is developing the Polygrene- E family for electrically conductive compounds with EMI shielding and static dissipative properties. These compounds have higher levels of fillers and combinations of Polygrene with other filler types. Because graphene is not abrasive, higher levels can be used without damaging equipment. Canadian graphene producer Nanoxplore announced in January this year that it had increased production capacity of its plant in Quebec to meet the need for an existing customer’s lightweighting initiative in thermoset sheet moulding compounds (SMC). The company is also seeing steady growth in sales of its graphene-enhanced thermoplastics, including PE, PP, TPO, and nylons, said Nima Moghimian, R&D Director at Nanoxplore. New graphene masterbatches made with 100%
recycled resins are also growing in demand. “These masterbatches are used as additives, particularly
