FEP & PFA Optically Clear Film made with Teflon™ fluoropolymers
(34)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.

PTFE Film made with made with Teflon™ fluoropolymers
(39) CS Hyde Company stocks skived PTFE (Polytetrafluoroethylene) film in a huge range of thicknesses, starting at .5 mil (.0005") and going up to 125mil (.125”). We sell this high performance PTFE film by the sheet, lineal foot, continuous footage, slit width (rolls), die cut (custom AND standard shapes), and/or laminated with a variety of adhesive options. PTFE is inherently super slippery and extremely temperature/chemical resistant, making it a highly suitable material to be used as a release sheet. For product information, samples, pricing, etc. please email- sales@cshyde.comExamples of electrical applications: capacitor films, harnesses for electrical wiring in automotive and aerospace applications, spacers for transformers and other electrical insulation applications where high dielectric strength and high temperature resistance are requisite. Virgin Grade, General Purpose - No Adhesive / White Color. Also available as PTFE Tape in multiple thicknesses, grades, and adhesives

Tefzel® (ETFE) Optically Clear Film (General Purpose Grade)
(8) Tefzel® Optically Clear Film is an extremely durable, thin polymeric film closely related to PTFE fluorocarbon resin. Of all the PTFE fluoropolymer family, Tefzel® (ETFE) is the most tough/ durable. Flexible and nearly 100 percent transparent, Tefzel® Optically Clear Film has excellent mechanical strength and reliability against cracking and abrasion. In outdoor applications, Tefzel® shows very little degradation over a long period of time despite constant UV radiation exposure, making it a suitable long term substitute for glass. Tefzel® Optically Clear Film features easy processibility and high-energy radiation resistance.Film types are:Type LZ--General-purpose film, Type CLZ--Treated one-side for improved cementability, and Type CLZ-20--Treated both sides for improved cementability. Tefzel® films can be thermoformed, laminated, heat-sealed, die-stamped, and oriented for use in many applications including high flex lightweight wiring insulation, composite part mold release, anti-corrosive valve linings, non-stick roll covers, rupture disks, high frequency microwave circuitry, pharmaceutical cap liners, sterile packaging, cable insulation, microphone electret membranes, photovoltaic cell glazing, anti-graffiti coverings, erasable surface coverings, automotive airbag systems, fuel hose permeation barrier, hot melt adhesive and thousands more possible applications.
