FEP is a copolymer of the monomers tetrafluoroethylene and hexafluoropropene with high resistance to heat input and chemical attack. Our FEP films offer high UV transmission, transparency and uniform thickness.

The foils are clamped in the resin tank as a separating element between the display/light source and the liquid resin. After prolonged use or wear of the foils, they should be replaced as clouding of the foils can affect the print result.
