Cécile Corriol and Xavier Couillens, Solvay, presented developments in performance PIN-FR polyamide (Solvay Technyl) materials responding to new requirements for electric vehicles. Emobility combines performance challenges including electrical characteristics (both power and data management), colour, fire safety specifications, laser markable, thermal resistance and mechanical properties. Plastics offer advantages to automotive design in replacing metals with lower weight and electrical insulation benefits. New application areas include high voltage connectors (orange colour requirement), power electronics (AC/DC), and battery systems (batteries, casing, cooling systems). Challenges for Solvay include finding HFFR (halogen free flame retardant) solutions with higher processing temperatures and with better mechanical performance, whilst continuing to meet UL94 V0 and Glow Wire fire resistance specifications.
