I purchased this film for some product development work that did not pan out. 500A= 500 Gauge (0.005"), General Purpose Virgin FEP film. This is for a 600' roll of the material. I currently have two unused rolls. American Durafilm is currently charging $6.65 for a linear foot of this material which would put the value of one of these rolls at $4000. I will sell for 1/4 of that price. Description DuPont™ Teflon® FEP film is a transparent, thermoplastic film that can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metalized, laminated—combined with dozens of other materials, and can also be used as an excellent hot-melt adhesive. This wide variety of fabrication possibilities combines with the following important properties to offer a unique balance of capabilities not available in any other plastic film. Chemical Compatibility • DuPont™ Teflon® FEP film is chemically inert and resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds such as chlorine trifluoride at elevated temperatures and pressures. • Low permeability to liquids, gases, moisture, and organic vapors Electrical Reliability • Superior reliability and retention of properties over large areas of film • High dielectric strength, over 6500 V/mil for 1 mil film (260 kV/mm for 0.025 mm film) • No electrical tracking, non-wetting, and non-charring • Very low power factor and dielectric constant, only slight change over wide ranges of temperature and frequency Wide Thermal Range • Continuous service temperature –240 to 205°C (–400 to 400°F) • Melting range 250 to 280°C (500 to 540°F) • Heat sealable Mechanical Toughness • Superior anti-stick and low frictional properties • High resistance to impact and tearing • Useful physical properties at cryogenic temperatures Long Time Weatherability* • Inert to outdoor exposure; no measurable change after 20 years in Florida • High transmittance of ultraviolet and all but far infrared radiation Reliability • DuPont™ Teflon® FEP film contains no plasticizers or other foreign materials • Conventional equipment and techniques can be used for processing: basic composition and properties will not be influenced • Rigid quality control by DuPont ensures uniform gauge, void-free film The convenience of FEP fluoroplastic in easy-to-use film facilitates the design and fabrication of this low-friction thermoplastic for all sorts of high-performance jobs. It is transparent and can be heat sealed, thermoformed, welded, and heat bonded. Superior anti-stick properties make it an ideal release film for many applications.
