Lubrizol Estane® AG 4350 Thermoplastic Polyurethane
Categories:	Polymer; Thermoplastic; Polyurethane, TP; Thermoplastic Polyurethane (TPUR), Polyether Grade
Material Notes:	Type: Estane® AG 4350 is a polyether based aliphatic polyurethane specifically formulated to be used as an adhesive interlayer without the need for a glass surface primer. This polymer is designed for flat die extrusion into sheet and film. Features: Designed for the lamination of optical transparencies using dissimilar products such as glass, polycarbonate, acrylic and cellulose acetate butyrate (CAB). Uses: Mid to low modulus, excellent low temperature impact resistance and tensile strength this is ideal for large span curved transparencies.
