Selection guide

Flame retardant plastics

Flame retardance is achieved either by inherent chemistry (PEI, PPSU, PEEK, PVC, fluoropolymers) or by additive packages (FR grades of ABS, PC, PA, PBT). UL 94 V-0 at 1.5 mm is the most common electrical-enclosure requirement.

What to look for

  • UL 94 V-0 grade documented at your wall thickness
  • No halogenated FR if a low-smoke / low-toxicity spec applies
  • Balanced impact and heat properties after the FR package
