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.
