Covestro DUREFLEX® PT1710S TPU
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Characterization: Dureflex PT1710S is a specially formulated aromatic polyether based film. Properties / Applications: Dureflex PT1710S is for applications requiring high moisture vapor transmission. Dureflex PT1710S maintains mechanical properties essentially equivalent to a conventional polyether TPU, yet this material allows water vapor to pass through it at a rate of 3 to 5 times greater. This material is intended for thin gauge film. Dureflex PT1710S is supplied on a polyethylene carrier. As with any product, use of Dureflex PT1710 in a given application must be tested (including but not limited to field testing) in advance by the user todetermine suitability.
