Daikin FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). Daikin FEP has a lower melt viscosity than PTFE and can be processed like other thermoplastic resins by the melt flow processes of extrusion, transfer, injection and compression molding. Because the bonding energy between its carbon and fluorine atoms is so high, and the molecule is completely filled with fluorine atoms, Daikin FEP fluorocarbon polymer has excellent thermal, electrical, and chemical stability. Daikin FEP offers superior reliability and retention of its properties in a wide thermal range from cryogenic to high temperature (-200°C to +200°C). Daikin FEP maintains its physical properties in extreme environments. It provides excellent chemical and permeation resistance including exposure to weathering, light, and moisture. A low dielectric constant and dissipation factor exist along with high dielectric strength over a wide range of frequencies and temperatures. Daikin FEP offers the lowest critical surface energy of any plastic material in addition to excellent water and oil repellency for non-stick and mold release applications. High Transparency: Products prepared from Daikin FEP are transparent with good transmittance of both ultraviolet and visible wavelengths; the lowest refractive index of any plastic and characterized by very low light reflection.
