DuPont® Teflon™ FEP (Type A) & PFA (Type LP) are optically clear Teflon™ films that benefit from the ability to be thermoformed, heat-sealed, plastic-welded or bonded. PFA film is very similar to FEP Film, except it has a higher melting point of (302C to 310C vs. FEP’s melt range of 260C to 280C). PFA Film is recommended over FEP Film for applications that require superior creep resistance at high temperatures, low-temperature toughness, and a higher flame resistance.  Teflon™ PTFE fluoropolymers are the most inert of all plastics and complie with USFDA regulations for food contact applications. FEP and PFA films possess superior anti-stick, low friction properties, strength and puncture resistance, chemical & solvent resistance, as well as high dielectric strength (over 7000 volts per mil for 1 mil). No electrical tracking, non-wettable (hydrophobic), non-flammable, non-charring and long term weatherabilliy.  CS Hyde FEP & PFA films offer superior reliability & retention of properties over large areas. FEP film meets the requirements of ASTM D-3368.

 FEP & PFA Applications:

-          Chemical resistant liners (tanks & diaphragms)

-          Optics lenses  

-          Release liners (DLP & SLA 3D Printer VAT Systems)

-          Solar Receptors

FEP Film & PFA Film is available in rolls, sheets, or custom width rolls. CS Hyde also has in house capabilities to laminate adhesive to FEP & PFA Film.
