ETFE Film – High Transparency, UV & Weather Resistant, Thickness Range 12.5–500 μm, Durable Fluoropolymer Membrane for Solar Panels, Greenhouse Covering, Roofing, Facades and Electronics Insulation
Product Overview
ETFE film is produced by melt extrusion of ETFE resin, featuring a smooth surface and excellent overall performance. The film supports heat sealing, welding, metallization, lamination, and thermoforming processes.
All films are manufactured in cleanroom facilities, available in thicknesses from 12.5 μm to 500 μm, and widths up to 1600 mm. Surface treatment (single or double-sided corona, chemical, or matte treatment) is available to enhance adhesion with other materials.
