Evonik has launched a new PIN FR polyamide 12 for e-vehicle busbars with electrical and fire safety, fast extrusion, adhesion. Busbars are metallic strips (e.g. copper or aluminium) which locally transmit high current power and are needed in electric vehicle batteries. The new Evonik compound ensures electrical insulation up to 1000 V and UL 94 V-0 (0.4 mm) fire safety. A 0.5 – 0.7 mm coating meets e-mobility insulation requirements. The compound can be used at operating temperatures up to 125°C and is available in RAL 2003 signal orange. High extrusion speeds, adhesion to metal (without adhesion promoters) facilitate processing, and high elasticity means that the busbars can be bent to small radii after extrusion without losing insulation protection.
