TPU films and sheets

Estane thermoplastic polyurethanes (TPUs) include adhesive and breathable grades as well as high-melt-point version for laminating higher heat polymers. The TPUs handle high-abuse applications such as conveyor belts and cable jacketing. They remain flexible down to –45°C (–50°F), reportedly well below the point other elastomers and many rubbers turn rigid and brittle. Many of the TPUs offer excellent flex fatigue not found in other elastomers.
