Pocan® BFN4232ZHR S1 by Envalior is a halogen-free, flame-retardant PBT that combines the strengths of PBT and polyamide 6/66. It offers dimensional stability, low electro-corrosion and strong electrical insulation at high temperatures, along with hydrolysis resistance, creep resistance and at break comparable to polyamide.
- It exhibits high elongation at break and good tracking resistance.
- It is ideal for use in connectors for ultrafast high-voltage charging, secondary 48-volt board supply and AI data center applications.
- It is free from halogenated ingredients and also contains no polyfluorinated alkyl substances (PFAS).
- It also has applications in housings and electrical components in the rapidly growing market for smart grid devices.
- Pocan® BFN4232ZHR S1 achieves a CTI A rating of 600 (IEC 60112), meeting the highest insulation class (IEC 60664-1) even in orange and black-unique for 25% glass fiber-reinforced PBT.
