280 Formex


FORMEX and FORMEX GK (or GK-BK) are flame retardant grades of polypropylene, extruded into sheet and primarily used for their electrical insulation properties. These materials meet the insulation requirements from most application due to their high dielectric strength (1460 V/mil @ 17 mil thick), low moisture absorption (<0.1%) and UL 94-V-0 flame class rating. Polypropylene provides exceptional scoring and bending characteristics resulting in superior folded parts.

Formex, the high performance insulating barrier, absorbs less moisture than other barrier materials resulting in superior performance.

  • Moisture Absorption of <0.02% Dielectric strength of > 1700V/mil at (18 mil).
  • V-0 Rated
  • Excellent scoring and die-cutting characteristics
  • 0.45 mm thick
  • Available in either White or Black
  • Maximum continuous temperature use 110°C
