Applications of Formex | ESPE Manufacturing
Uses of Formex Insulating Material
Formex material is composed of flame-retardant polypropylene that prevents electrically charged components from arcing, protecting the users, equipment, and maintenance personnel. In the event of electrical fire, these flame retardant properties assure that the Formex material will not melt or combust up to 115°C / 239°F. It appears in a variety of applications as an electrical insulator and barrier.
