Estane® AG 4350 TPU
TPU(热塑性聚氨酯)
路博润 (Lubrizol)
产品描述
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.
