compounds for high voltage applications
flame-retardant PA6 compounds Durethan BKV20FN01, BKV30FN04 and BKV45FN04. A special feature is Durethan BKV45FN04, which is 45% glass fibre-reinforced yet still easy-flowing. It passes the UL94 flammability test with the top classification V-0 with a test specimen thickness of 0.4mm. “Its high stiffness and strength make the material ideal for not only structural components in the battery such as cell frames and end plates, but also large, high-voltage connectors requiring high mechanical stability,” says Haspel. The compound is also characterised by high tracking resistance at high electrical voltages. This also applies to the two other polyamide variants. For example, orange- coloured Durethan BKV30FN04 has a CTI (com- parative tracking index, IEC 60112) value of 600. The company adds that Durethan BG30XH3.0 is a good choice for exceptionally low-warpage structural plastic. It has been reinforced with a mixture of glass fibres and glass microbeads. The H3.0 thermal stabilisation is copper- and halide- free, which prevents electrical corrosion in the vicinity of live metal parts. The hydrolysis-stabilised, glass fibre-reinforced
PBT compound Pocan BF4232HR is also part of the new product series. In the colour orange, it also achieves V-0 classification in the UL94 flammability test with a test specimen thickness of 0.4mm. High hydrolysis resistance is demonstrated in the long-term test SAE/USCAR-2 Rev. 5 of the Ameri- can Society of Automotive Engineers (SAE), which was designed especially for plug connectors. At Lanxess HPM, the new compounds form part of a development focus on new forms of mobility. In ad- dition to halogen-free flame-retardant polyamides, whose additive packages are specially designed for electro-mobility applications, HPM also offers, for example, highly heat-conductive PA6 versions and electromagnetically shielding compounds. For connectors and switches in smart home
systems, Lanxess has also introduced the PA6 compound Durethan BG60XXF. The company says that it is a low warpage plastic, and its uses include switch holders in a product range from a manufac- turer of electronic components. The component meets extremely high standards of planarity, dimensional tolerance and rigidity. Covestro has developed new polycarbonate

materials for electro-mobility applications, includ- ing electric surfboards. With electro-mobility applications rising significantly, the new flame retardant PC/ABS blends make batteries safe, durable and waterproof. In addition to the produc- tion of injection moulded battery casings seen in current electric car projects, leisure products such as Onean electric surfboards from the Bilbao- based Aquilaboards are also benefiting. The exchangeable batteries for this surfboard are equipped with impact-resistant, durable and flame-retardant casings made of Bayblend FR3010. ‘A new sport is coming’ is the slogan used by Aquilaboards, a spin-off of the Spanish company Bizintek specialising in engineering and product design. The manufacturer of electric surfboards currently offers three products in its catalogue, which are expected to develop a new environmen- tally-friendly sport. The Carver is a motorised surfboard with a power of 5 kW, while the Carver X for heavier people or those who want to reach a higher speed has 10 kW of power. The Manta is a model suitable for everybody that comes with a 750 W jet engine that enables longer excursions. Depending on the board, riders can travel at speeds of 10-45 km/h. All three models have a powerful jet drive and the boards come with a plug and play battery, which can be easily replaced from the body of the board after a charging time of just 2.5 hours. The Carver X, with its higher perfor- mance capacity, works with two of them. “The plastic material impresses with its balanced
