Syensqo part bio-based long glass fibre PIN FR polyphthalamide for structural, heat, fire and electrical protection of EV batteries. The long fibres create a complex 3D network during injection molding (using standard equipment) ensuring retention of mechanical properties at high temperatures and during demanding operational conditions. Non-halogenated flame retardants ensure UL 94 V-0 (0.8 mm for certain grades). The compound can resist direct flame at 1000°C for more than ten minutes and also high electrical resistance (tracking index > 600V). The compound can replace metal in battery endplates, structures and holders, enabling lightweighting and improving electrical safety, whilst protecting against thermal runaway, fires and mechanical damage. Production of the resin is partly bio-based and uses 100% renewable electricity.
