路博润ESTANE T470A TPU

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