DyFilm® Polyester films

DyFilm® is a polyester film obtained by the condensation between ethylene-glycol and terephtalic acid. Thanks to its excellent physical, chemical and electrical properties, DyFilm® is universally accepted and requested in all markets, industries and applications where a polyester film is required.

Its excellent dielectric properties make it particularly suitable for applications in the field of electric insulation in machines up to class B (130°C), as internal protection for cables, substrate for adhesive tapes and release film in glass-resin compounds.
