Flexbase™ Flame-Retardant Copper/Polyester Film Laminates

 

FEATURES

  • Dielectric: Stabilized PET film.
  • Adhesive: Modified polyester epoxy.
  • Available Coppers: Rolled-Annealed (RA), Electro-Deposited High-Ductility (EDHD) or As-Rolled Untreated (ARNT). EDHD foils are suited for general use and flex to install applications. RA foils are suitable for dynamic flexing applications. ARNT foils are valuable for high frequency applications that require a smooth copper surface on both sides.
  • Constructions: Contact Sheldahl Customer Support for available constructions. Custom constructions may be ordered for high volume opportunities.
  • Processing: High quality flexible circuits can be produced using standard circuit manufacturing procedures.
  • Preferred Storage: Material should be stored in dry, ambient temperature. Excessive exposure to heat and moisture may cause copper oxidation.
  • Shelf Life: Typical expected shelf life is 12 months when stored as recommended.
  • G1802 laminates have been developed specifically for flexible printed circuitry and automotive applications that require the safety of a flame-retardant system.
  • U.L. certified to 94-VTM-O for select constructions.
