FORMEX (GK-17)

FORMEX and FORMEX GK (or GK-BK) are flame retardant grades of polypropylene, extruded into sheets and primarily used for their electrical insulation properties. These materials meet the insulation requirements for 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.
