The PC + ABS blend Bayblend FR3010 from Covestro combines excellent mechanical parameters with good flame-retardant properties and
outstanding chemical resistance
property profile, which is a perfect fit for this application,” says Miguel Angel Montero Diaz, Director of Polycarbonates at Covestro Iberia. “Among other things, it combines high heat resistance with excellent mechanical parameters, good flame retardant properties and outstanding chemical resistance.” At first glance, the battery requirements for
Onean jet boards hardly differ from those for e-bikes or electric off-road motorbikes. When in use, they are exposed to the wind and weather, heat up during charging and discharging and can sustain impacts. The Bayblend FR3010 protects the battery and the unreinforced injection moulded casing has improved heat resistance (Vicat/B 120 of 110°C), with good impact resistance and stress cracking behaviour. Covestro adds that the dimensional stability of the surfboards has also proven to be excellent, since the batteries must always fit perfectly into the sockets: gaps can never open up that will allow moisture into the battery, particularly for applica- tions in water. Bayblend FR3010 also achieves UL94 V-0 at a wall thickness of 1.5mm and Class V-1 at 1.2mm. The blend’s high resistance to chemicals is another advantage, for example, in contact with sunscreen and insect repellents. The material is also suitable for recycling. A recent Life Cycle Assessment (LCA) has found a laptop cover made of Maezio continuous fibre-

reinforced thermoplastic com- pounds from Covestro can signifi- cantly reduce its carbon footprint
by more than 70% compared to one made from a conventional aluminium- magnesium alloy. The LCA study, conducted in line with ISO 14040/14044 standards and reviewed by an independent panel of LCA experts
chaired by Dekra Assurance Service, compared a comprehensive range of parameters to assess the environmental performance of a laptop A-cover made from the two materials which are typically used for premium laptops. In all impact categories and scenarios, the composite laptop A cover shows better environmental performance than the aluminium-magnesium alloy cover from the extraction of raw materials until the end of life. Maezio composites are based on continuous carbon or glass fibres impregnated with polycar- bonate, thermoplastic polyurethane (TPU) or other thermoplastic resins. “Thermoplastic composites are ideally suited for
producing thinner, lighter and more robust parts for IT devices that meet the needs of tomorrow,” says Lisa Ketelsen, head of the thermoplastic composites business at Covestro. “The fact that Maezio thermoplastics are not only mechanically competitive but also environmentally advanta- geous will provide the electronics industry and many other industries with a powerful solution for reducing carbon footprint and reaching their sustainability targets.” Compared to aluminium-magnesium alloys,
Covestro adds that Maezio composites can also achieve weight reductions of approximately 15%, and the composite A cover exhibits a similar good bending and torsional rigidity compared to the metallic material. The composite A cover meets the V-0 classification of the UL94 standard. The technology also enables fast and efficient produc-
