them ideal for compact, lightweight designs in EV applications. “The Amodel PPA portfolio offers high CTI,
excellent thermal and mechanical properties, and inherent sustainability,” said Nicolas Batailley, Marketing Manager Automotive. “These materials give engineers the flexibility to design lighter, more compact, and environmentally friendly power modules that meet the current and future needs of the automotive industry.”

Towards sustainability It is estimated that over 80% of the plastic parts used in automotive applications end up in landfills or incinerators. To address this issue, part of a planned revision to the EU’s End-of-Life Vehicles (ELV) Directive stipulates that a minimum of 25% of the plastics used in vehicles sold in 2030 must be sourced from post-consumer recycled (PCR) materials. Of that, 25% must be from circular or closed-loop streams within the automotive indus- try. Historically, PCR plastics have been of low and inconsistent quality making them unsuitable for demanding automotive applications, but recent advancements seek to challenge the status quo. Earlier this year, Polyplastics launched a new
PPS grade that boasts significantly improved thermal shock resistance. Durafide PPS 1140HS6, a 40% glass-filled grade, meets the requirements for metal insert moulding, particularly busbars for EVs, and can be easily collected without being sepa- rated from other PPS components during recycling. Busbars conduct high-voltage currents in various electrical parts like motors, power control units, and lithium-ion batteries. Polyplastics says the material design ensures thermal shock resistance by minimising residual strain during moulding and homogenising linear expansion to mitigate internal

stress. The new grade eliminates moulding imperfections, enhances performance without the need for impact modifiers, and offers better flowability than standard materials. Borealis has introduced Borcycle GD3600SY, a
glass-fibre reinforced PP compound with 65% PCR polymer content. It will first be used in automotive interiors in a landmark project with thermoplastic injection specialist and Tier 1 supplier Plastivaloire and Stellantis. The new compound will initially be used in centre console carriers in the new Peugeot 3008, marking the first instance of a compound such as this being used in series production for large interior automotive applications and proac- tively addressing the requirements of the ELV regulation. “Developed and manufactured in France, the centre console structure of the new Peugeot 3008 is a major step towards a more sustainable automotive industry,” commented Dominique Manceau, Innovation Director at Plastivaloire.
