New flame-retardant films from DuPont Teijin Films movie database promise to help design engineers in the electronics, transportation, construction, and label industries deliver high performance at low cost. The halogen-free, white Teijin[R] Tetoron[R] UF Polyethylene terephthalate (PET) films and the Teonex[R] QF polyethylene naphthalate (PEN) films combine chemical resistance, strength, and insulation properties with the films VTM-0 flame rating available from UL 94 flame classification testing.
"We have applied our proprietary science to help our customers deliver high-quality products for these cost-sensitive industries," says Scott Gordon, business development manager, DuPont Teijin Films. "Traditional PET and PEN polyester films are well known for their performance and reliability characteristics, and these two new film types have combined those properties with the highly desired VTM-0 certification."
Other commercial film types offer inherent flame retardance, but often at a high price. Most commercial polyester films are inherently resistant to heat, chemicals, and water absorption; however, the typical flame classification rating is at the VTM-2 level or higher. Consequently, PET polyester films have been used only in a limited range of electronics applications, or in some cases the PET's flame retardance was achieved through the use of additives or coatings containing halogens, which are no longer permitted in many industries.
