PIN FR performance solution for PBT

Envalior (pinfa member) has launched a non-halogenated PBT with high electrical resistance and physical performance. The non-halogenated PIN FR polybutylene terephthalate (PBT) achieves CTI A 600V (IEC 606112), meeting the highest insulation class (IEC 60664-1, including when coloured EV orange) and UL 94 V-0 @ 0.75 mm fire performance. Properties include dimensional stability, low electro-corrosion, electrical insulation at high temperatures, hydrolysis resistance, creep resistance and elongation at break comparable to polyamides. Compounds are available with and without glass fibre reinforcement. Applications include e-vehicles for high-voltage charging (800V), secondary supply for hybrid vehicles, electrical components and housings and data centres.
