Product Family: Aliphatic Polyether

The premium choice for optical interlayer films

Extremely clear aliphatic polyether film is used as an optical interlayer film for glass lamination and as an adhesive interlayer for textile lamination and armoring. With unmatched optical clarity, lay-flat and overall high quality, Argotec is the leading global supplier of thermoplastic polyurethane interlayer. Argotec’s optical interlayer films are used extensively in commercial and military aircraft canopies and windows, they can also be found in construction, security and automotive applications requiring extremely high strength and impact resistance. Offering design flexibility aliphatic polyether films are compatible with glass, polycarbonate, acrylic and CAB. They also have excellent temperature resistance, and superior electrical insulation properties that make them ideally suited for use as an adhesive layer between glass and the electronic components in touchscreen monitors.
