ESTANE 58280 TPU Technical Data Sheet Type: Estane? 58280 is a polyether-type thermoplastic polyurethane (TPU) compound. Features: High resiliency compound, with unique physical properties such as low tensile and compression set, high rebound resilience, good hysteresis and low specific grity. Uses: General extrusion techniques or by injection molding. Excellent for applications such as cable jackets, hose and tubing, and a variety of injection molding applications such as wheel tires, rebound balls, etc. *These are typical values and should not be used for establishing specifications. Contact your representative for ailability and commercialization status. ** Differential Scanning Calorimeter; melting point was obtained from the second heat on a 20 mg sample with a heating rate of 10°C/min. Handling Considerations Properties of all thermoplastic polyurethane products in the molten state are adversely affected by moisture. Although Estane? TPU compounds are dry when packaged, trace amounts of moisture can be absorbed during storage and handling. For best results, always dry the material 2 hours at 104°C (220°F) in a dehumidifying hopper dryer.
