路博潤(rùn)ESTANE T470A TPU

Technical Data Sheet Type: Estane? T470A is a Shore 77A, polyester grade, plasticizer-free, with low hardness thermoplastic polyurethane (TPU). Uses: Injection Molding, Extrusion *Test samples were annealed at 100o C and 24 hours at room temperature before testing. **These are typical values and should not be used for specifications. Injection Molding Guide These settings are to be used only as a guide. This is a typical injection molding temperature profile based on the Test Machine (conditions based on a 75 ton machine with a general purpose screw – L/D 17 – ? 35mm). The optimal run conditions for specific equipment will vary depending on the machine and mold design.
